LaxNumbers – About Us
Larry Feldman, founder of Laxpower, and Ranking Technologies, founder of MYHockey Rankings, joined forces to create Laxnumbers in February of 2019. With over 40 years of experience in the rankings industry combined, Laxnumbers’ mission is to create a centralized database of lax related information while providing high school, college and pro lacrosse rankings to the lacrosse community across North America.
Larry Feldman, a former Air Force Reserves Lt. Colonel and aerospace engineer, founded Laxpower in 1997. Larry attended undergrad at University of Pennsylvania and played on their varsity, JV and freshman lacrosse teams. His time at Penn instilled love and passion for the game of lacrosse that he still carries with him today. He looks back fondly on those years of watching and occasionally playing against the likes of Maryland, Syracuse, Princeton, Harvard, Yale, Cornell, Lehigh, Lafayette, Swarthmore, Villanova, and others. After his time at Penn, he worked as a 3-D software architect for Intel Corporation, developed a “3-D Engine” for a British gaming company, and served as a senior staff member at Los Alamos National Laboratory. Larry possesses post-graduate or doctorate degrees from the University of Oklahoma, University of Southern California, University of California, Berkeley, Auburn University and Stanford University. In addition, he has received five awards for his work, including first prize in an IBM supercomputing contest, two Cray Research Supercomputer “Gigaflop” awards, an Autodesk First Prize in Scientific Graphics, and first prize in MicroCad Magazine’s Engineering Graphics Contest.
Ranking Technologies provides rankings, statistical analysis and consulting to organizing bodies across a wide array of youth sports: Hockey (USA Hockey), Lacrosse (Ontario’s OLA, Alberta’s ALA), Racing (USAC) and Basketball (CYO). Ranking Technologies began working with the Ontario Lacrosse Association in 2012 and Alberta Lacrosse Association in 2018. Ranking Technologies is also the group behind MYHockey Rankings. MYHockey Rankings was found in 2003 as a way for fans of youth hockey to spread the love of the game and to help team’s schedule appropriate competition. It quickly grew into something much larger. Containing 240 ranking categories, 2,600 associations, 4,000 rinks, 22,000 teams and 300,000 game scores annually, MYHockey Rankings has become the go-to website for the youth hockey community.
Laxnumbers’ ratings are computed mathematically, with no subjective weighting. Laxnumber computes an average performance rating for each team based upon how well they play against other teams and how good those teams are. There are two real inputs to this rating, they are “AGD” or average goal differential and “SCHED” or strength of schedule. AGD is currently calculated by accumulating the goal differential of each game, to a maximum of 10, and then dividing it by the number of games played. Using a max game goal differential of 10 can “penalize” teams that blow out opponents, but this is common in rating systems as it takes away the incentive for teams to run up scores and allows them to have a bad game by capping the mathematical damage. The strength of schedule is computed by averaging the rating of each game opponent. AGD and SCHED are then added together to compute a team’s official rating. A team’s rating typically is not reflective of the team’s best or worst games, but a mathematically computed average performance rating that translates game scores into a numeric representation of team performance.
The Laxnumbers’ team looks forward to supporting the lacrosse community for 2019 and beyond. We appreciate your patience and support!

Power restored at Los Angeles International Airport
LAX is the latest airport to roll out automated security lanes
Los Angeles Airport’s Tom Bradley International Terminal has opened its first automated screening lanes, which could mean passengers will be spending less time in security lines this holiday season.
Power has been restored at Los Angeles International Airport after a widespread outage.
Airport officials alerted travelers on Twitter Tuesday that a “power interruption” was affecting their systems and operations around 12:30 p. m. PT.
“A power interruption is currently impacting operations at terminals 1, 2 and 3. Tom Bradley and terminals 4, 5, 6, 7 and 8 have full power,” tweeted LAX’s official Twitter account. “Crews are responding to effected areas. Thank you for your patience.”
Twenty minutes later, officials noted that the “power is being restored now to all terminals. Thanks for your patience.”
The brief outage didn’t appear to have a lasting affect on flights – there have been a total of 44 delays and 14 cancellations at LAX on Tuesday, according to Flight Aware.

Power is being restored now to all terminals. Thanks for your patience.
— LAX Airport (@flyLAXairport) March 3, 2020
LAX wasn’t the only area to experience an outage in Los Angeles.
The Los Angeles Department of Water and Power, which provides electricity to LAX, said “a large portion of West L. A.” was hit by the power outage, LADWP spokesperson Mia Rose Wong confirmed to USA TODAY.
The temporary outages affected about 26,000 customers of the 1.5 million homes served by LADWP, Rose Wong added.
“For those of you inconvenienced earlier today by the brief power outage in the #WestLA area, we appreciate your patience and understanding,” tweeted the LADWP’s official Twitter page. “Again, the outage was fully restored after 20 minutes. Thank you!”
The cause is still under investigation.

The vacuum cleaner does not suck up garbage well: what is the reason? ─ Blog
Everything was fine, but at some point you found that your vacuum cleaner began to suck up debris poorly. The power has dropped several times, and your general cleaning has turned into a major torment. What is the reason and is there anything you can do about it?
In 9 cases out of 10, it is certainly possible. And at home, without the help of outside help and replacement of spare parts. So why isn’t your vacuum cleaner pulling?
Power regulator set to minimum
This is trivial, but, nevertheless, look at what mark the power regulator is installed (if any).You could have set the regulator to a minimum, for example, for delicate cleaning of a product made from any sensitive fabrics, and then forget to rearrange it. Therefore, now there are difficulties.
Waste container (bag) overfilled
An overfilled garbage bag or container is the most common reason a vacuum cleaner does not pick up garbage well. It seems like everything is simple, but many people simply forget to clean the container in a timely manner and shake out the bag. Yes, and it is advisable not only to shake out the reusable fabric bag, but also to wash it sometimes.
Clogged filters is an equally common reason for a drop in the power of the vacuum cleaner. Clogged filters interfere with the free flow of air, so the pressure drops and the suction force, accordingly, also. Filters need to be cleaned regularly or washed (depending on the type). By the way, many models of vacuum cleaners have several filters, including directly on the engine. All filters must be clean.
Clogged hose, nozzle or telescopic tube
Look if a foreign object is stuck somewhere on the way to the garbage bag: a sock, a bag, a small toy, a piece of paper, etc.When cleaning in the far corners of the room, you don’t always see what the vacuum cleaner is pulling in. Therefore, you wonder why the vacuum cleaner does not suck. Of course, a foreign object is interfering with the air flow and the operation of the vacuum cleaner.
An unauthorized hole in the hose can also interfere with normal air flow. Simply put, if the hose breaks, then the air flow will go out under pressure, and not go in. And, accordingly, it will not be able to draw in the garbage inside either.The hose should be repaired or replaced.
The engine power has dropped
Over the years, even the highest-quality engine loses power over the years. The brushes in the motor can wear out, the motor can overheat due to clogged filters. All this has a detrimental effect on the power of the device. At home, you can easily clean the filters, remove the cover of the vacuum cleaner and remove dust deposits from the engine. If you have special skills, you can check and change the brushes of the electric motor.Experts do not advise to delve into the algorithm of how to disassemble the motor of the vacuum cleaner. Simply because almost any motor repair is not economically feasible – it is easier to add a little more money, buy a new engine in the assembly and replace the old one. Especially if you buy a motor or any other part from us at ALM-zapchasti. You get not only colossal savings by buying at almost wholesale price. You also get a manufacturer’s warranty, as well as the confidence that you bought an original spare part, and not a fake.
So, today you learned about all the main reasons why the vacuum cleaner pulls poorly. Most of them, as you have seen, are easily removable at home. And you can always find the components you need for repair on our ALM spare parts online service!

What to do if Samsung vacuum cleaner sucks poorly
A vacuum cleaner may not pick up debris well for a number of reasons, which are listed below.Check each one in turn.
Dust container full
Check the dust container: bag or container. If there is debris, remove it.
Photo 1. For example, it looks like a container-dust collector on a vacuum cleaner with an aquafilter Samsung SD9480
Clogged hose, tube or brush
Check the corrugated hose, telescopic tube or brush for clogging. If debris is stuck in them, remove it.The brush and hose can be rinsed under high pressure running water and dried thoroughly.
If, after cleaning, the suction power of increased , then everything is fine with the vacuum cleaner, continue to use it.
If there was no debris in the hose, tube or brush, or the suction power of did not increase , check the following recommendation.
There are two filters in the vacuum cleaner: pre-motor (installed in front of the electric motor) and exhaust (installed after the electric motor).If any of them is clogged, the suction power drops.
Filters look different on different models and are located in different places. Detailed information about them is given in the user manual.
Photo 3. For example, this is how the pre-motor filter of the vacuum cleaner Samsung SD9480
Photo 4. For example, this is how the exhaust filter of the vacuum cleaner Samsung SD9480
To check the status of the filters:
Remove the pre-motor filter from the vacuum cleaner and switch it on.Check the suction force by hand. Never vacuum without a filter.
If the suction power without pre-motor filter increases , clean the filter and reinstall it. Check the suction power again.
If the suction power does not change after installing the filter, then everything is in order with the vacuum cleaner, continue using it.
If the suction power decreases after installing the filter, then the filter is unusable. Purchase a new filter.
If the suction power does not change without the pre-motor filter , remove the exhaust filter from the vacuum cleaner. Check the suction force by hand without two filters. Never vacuum without filters.
If the suction power increases without filters, clean both filters and reinstall them. Check the suction power again.
If the suction power does not change after installing the filters, then everything is in order with the vacuum cleaner, continue using it.
If the suction power decreases after installing the filters, then the filters have become unusable.Purchase new filters.
Vacuum cleaner malfunction
If, without both filters, the suction power does not increase , then the vacuum cleaner is defective. It is impossible to determine the malfunction at home and without special knowledge, therefore, the intervention of the service center master is required.
Where to buy new filters
New filters are sold in official Samsung service centers and home appliances stores.
I cannot find or understand the manual for the vacuum cleaner

Opel engine power limitation
The on-board computer of the Opel model range, which includes such cars of the same type as Astra J, Insignia, Zafira, Mokka, quickly responds to serious malfunctions.One of the most unpleasant notifications on the central display of the onboard computer for car owners is the message “Engine power is limited”. Since an ordinary driver is not able to remember and analyze all alphanumeric error codes (displayed on the small display), this notification should be given special attention.
The on-board computer of the Opel model range, which includes such cars of the same type as Astra J, Insignia, Zafira, Mokka, quickly responds to serious malfunctions.One of the most unpleasant notifications on the central display of the onboard computer for car owners is the message “Engine power is limited”. Since an ordinary driver is not able to remember and analyze all alphanumeric error codes (displayed on the small display), this notification should be given special attention.
Causes and consequences of a drop in ICE power
Periodic or constant power drops can be caused by dozens of reasons.For the Opel lineup, which includes the latest generations of the Astra J sedan, Insignia station wagon, Zafira minivan, Mokka crossover, throttle valve faults (error code P2135) and fuel pump control failures (error code P0627) are considered typical breakdowns.
In addition, a drop in the power of a diesel or gasoline engine may be associated with:
- Clogged filters. A simple malfunction requires checking, replacing the air, fuel, oil filters.
- Wear, carbon deposits of spark plugs. When replacing, we use candles recommended by the manufacturer.
- Signals from the crankshaft position sensor.
- Breaks, short circuits of electrical wiring. Complex diagnostics requires instrumental testing of all circuits of the electrical equipment of the engine.
- Depressurization of the exhaust system. Most often, it is necessary to replace the exhaust manifold gasket.
- Failure of the knock sensor.The contact group is checked, the sensor is replaced.
- ECU malfunctioning. Eliminated by reprogramming or replacing the electronic unit.
The consequences of a periodic drop in power are well understood by experienced drivers. In difficult road situations (for example, when overtaking a convoy of trucks for a long time in the oncoming lane), the loss of dynamics can lead to consequences. For a driver who does not have the knowledge of a programmer, there is no point in memorizing and analyzing hundreds of error codes.This is the business of professionals who know the models of the German brand well.
If the message “Engine power is limited” is constantly on, the machine cannot be operated. You need to immediately contact a qualified car service. If, after starting the engine, the car drives normally, but after 300-500 meters it loses power, it is better to call a tow truck.
For 8 years of work with all models of the popular German brand, our craftsmen have perfectly studied the design flaws and “weak points” of Opel cars.If you order diagnostics and engine repairs in our car service, you are guaranteed the speed of work, the correct technologies for disassembly, replacement of damaged units, and motor assembly.
When repairing engines, MaDCaT Customs uses proprietary tools and Opel dealer equipment. According to the reviews of regular customers, the real advantages of cooperation with a car service will be:
- qualification of auto mechanics;
- work on the technological maps of the automaker;
- accurate analysis of the archive of error codes;
- Possibility of flashing the engine ECU, carrying out chip tuning;
- Convenient location of a car service in the North-West of Moscow.
How to improve computer power and PC gaming performance?
How to replace a spare part and increase the power
It should be understood that not always replacing one component can save the situation, sometimes the “bottleneck” of the computer is not at all in the place where you are looking for it. To prevent this from happening, you need to evaluate the performance in the complex. If among the list above there is no bright problem in your PC, then it is quite possible that it is simply outdated. For all of these situations, look for a solution – below.
The heart of a gaming computer. She is responsible for the performance when playing graphics. The better the graphics in the game and the higher the resolution you set, the more power will be required. Modern cards are made for a specific screen resolution. For example, the RTX 3060 Ti is made for 2K monitors or for widescreen monitors with vertical scanning at 1080P. Game developers usually adjust performance to these standards. That is, if you buy yourself an RTX 3060 Ti, then all modern games are guaranteed to work on 2K and with any 1080P monitor.
What do you need to know when installing a graphics card?
Replacing a video card is very simple from a technical point of view – just unscrew one fastening screw and take it out of the case. The mounts may differ depending on the case and motherboard model, but in general it’s very easy. The cards are universal, that is, any card fits any motherboard, the connector is standardized. Monitor outputs are also universal and in extreme cases the adapter costs a penny.
The good news ends there.The problem is in choosing a video card. You can put an infinitely powerful video card in almost any PC stool, but in this case you will not be able to use it 100%, the weak processor power will not be able to reveal its potential in games.
If you are going to completely update your computer in the near future, then you can take a more powerful card and drive it for a couple of months with the potential that will be available to your hardware at that time. But if you do not want to completely throw out your old computer, then choose a simpler card.It all depends on your processor. Here is an approximate table of correspondence between the current models of video cards and processors.
|FPS||2 cores 2 Ghz +||2 cores 3 Ghz +||4 cores 2 Ghz +||4 cores 3 Ghz +||6 cores|
|RTX 3060 Ti|
|RTX 2080 Ti|
|RTX 2080 SUPER|
|RTX 2070 SUPER|
|RTX 2060 SUPER|
|GTX 1660 Ti|
|GTX 1660 SUPER|
|GTX 1060 6GB|
|GTX 1060 3GB|
|GTX 1050 Ti|
Take a look at the specs of your CPU and you will see the approximate card models that suit you.Not all of them pull modern games at maximum speed, for example, the GTX 1050 Ti is not capable of this. You can be sure that even if you have old processors with such characteristics, the cards will work to their fullest. There is no graph with eight-core pebbles, you can put any card on such things, except for the most top-end type RTX 3090.
Power, Cooling & Form Factor
Pay attention – any video card has such a characteristic as “minimum power supply”, the top-end cards write power consumption in watts, this is convenient if you assemble a system of several cards.Your power supply is most likely not designed for the gluttony of modern components, it will have to be updated. If, when assembling a computer, you were supplied with a power supply unit with a margin, then you can use it, just compare the required indicators with the capabilities of your power supply.
The second most important factor is cooling. The more productive a piece of iron is in your PC, the more heat it generates. It is advisable to update the case or at least add fans, in the most extreme case – open the lid. Cooling is a separate topic, in this article we will only write that it should be enough.
Modern cards are quite large, and old cases are not always designed for such a length of the board. It is also possible that you have an old type of case with a top-mounted power supply, in which case the hard disk mounts are located at the bottom, closer to the front wall, which may interfere with the installation of the card. Compare its physical dimensions and measure the body so that you do not have to saw it.
If you decide that the processor is weak, then everything is a little more complicated. It will not work just like that to change the pebble to the first one that comes across, they have different connectors.
The type of processor socket is called a socket, and many companies are constantly releasing new types. AMD in this regard is a little more modest and already several generations of processors are included in AM4, Intel, on the contrary, is trying to make each new generation of CPUs on new sockets.
If you are lucky, then you have a popular socket and you can easily find the required processor at the flea market, if not, a replacement motherboard.
So, if you need to update the processor, then look at what socket you have on the motherboard.The easiest way to do it this way: take a look at what processor model you have, and the socket should be indicated in its technical characteristics on the manufacturer’s website.
There is a small caveat – if your motherboard has an FM2 connector, there is also an improved FM2 + version of it. FM2 processors will work on a motherboard with FM2 +, but vice versa – no, FM2 + processor will not start on a motherboard with FM2 socket.
What performance is needed?
If you are limited by the scope of your socket and do not want to update the motherboard, then just take the best possible, usually this gives a small, but still performance gain.
If you are ready to buy a new set of motherboard + processor, then choose from the modern models that are presented on HYPERPC.RU, our computers are assembled from the latest components that are optimal in terms of price and performance.
It is best to have at least 6 cores in stock, you only need Hyperthreading if you plan to do photo and video processing, as well as to work in 3D environments. For games, 6 cores are enough, no additional threads are needed.It is better to build a more powerful computer based on 8 cores.
Memory is as simple as possible – at least 8 GB of RAM, better than 16 GB. This should be enough for most games. Today, two versions of DDR3 and DDR4 memory are relevant, determine which dies you have now and buy exactly the same ones. Here are some rules:
- The higher the frequency, the better. But it is limited by the capabilities of the processor. In order not to overpay, see the characteristics of the pebble – they indicate the maximum possible memory frequency.There may also be a limitation on the motherboard: if the computer is assembled correctly, then they will be at the same level, if the assembler is mistaken, the memory will work at the lowest available frequency value.
- It is best to put identical dies on one channel, it is best to buy a pair of identical dies in one place at once. If this is not possible, then take at least one manufacturer with identical characteristics.
- Occupy both memory channels with dies, this will increase the speed.
- Radiators for RAM slats are often just a decoration. Cooling the RAM is needed only in very specific situations, when the memory is constantly loaded with new data. In games, it is impossible to achieve such a load, it can only be provided by engineering programs or something similar.
Even if you are not experiencing boot issues, buy an SSD. This is a modern solution that allows you to generally speed up your computer several times.Install the system, programs and games on it. In the games themselves, it will not affect the FPS, but it will allow you to load faster.
And if you do not want to delve into all these technical details, you can simply order a computer upgrade from HYPERPC.
90,000 Between “atmosphere” and “turbo”. Which engine to choose?
As it was said in the Soviet comedy Beware of the Car: “Everyone who does not have a car dreams of buying it. And everyone who has a car wants to sell it. ”
Since the release of the film, more than fifty years have passed, the cars have become many times more complicated in technical terms, the model range has expanded by several orders of magnitude.But a private car is still a serious purchase for a family, and no one wants to make a mistake with the choice.
So, you have a treasured amount in your hands, you have already decided on the brand and model of the future car. And here an important question arises: with which engine to take the car? If the question of choosing a diesel or gasoline engine for your car is decided in favor of the latter, another dilemma arises: naturally aspirated or turbocharged.
In our country, most of the popular models, whether budget sedans or super popular crossovers, are offered with both turbocharged and naturally aspirated engines.Moreover, the higher the class of the car and its price, the wider the range of turbocharged units. This is a worldwide trend: turbo engines are gradually replacing naturally aspirated engines.
Before making a choice, it is worth understanding the main differences between atmospheric and turbocharged power units, as well as identifying their strengths and weaknesses.
How it works
The main difference between the two motors is the way air is supplied to the cylinders. In the naturally aspirated engine , the air is drawn by the vacuum inlet, which is created on the stroke – the piston simply lowers and draws in air.In the turbocharged engine , forced charging works – more air is injected into the cylinders using a turbocharger.
In fact, the turbocharged engine is an upgrade of its predecessor – the classic naturally aspirated engine. The main purpose of this invention is to increase power without increasing the volume of the cylinders. The turbocharged gasoline engine allows for a higher compression ratio in the combustion chambers. Due to the fact that air is supplied to the combustion chambers under pressure, a more complete combustion of the fuel-air mixture is achieved.
The turbine consists of two parts: a rotor and a compressor. The engine produces exhaust gases during operation. These hot gases, entering the rotor under pressure, spin up the turbocharger, acting on the turbine blades. Only then do they enter the muffler. The rotor shaft, rotating, drives the compressor, which pumps air into the combustion chambers, forming an additional compression ratio.
Let’s use a simple example to illustrate: if the volume of the engine is 1.6 liters, then the power of the classic aspirated engine will not exceed 100-110 liters.with. In turn, a turbocharged engine with the same volume will be able to produce up to 180 hp.
By the way, turbocharged engines have their own small classification.
- Mechanical blower . At the inlet there is an air pump – a compressor, which is driven from the engine crankshaft.
- Turbocharger quarrels , which uses the energy of the exhaust gases. We discussed the principles of its operation above.
A bit of history
Gottlieb Daimler, one of the creators of the first internal combustion engine, experimented with a crankshaft-driven supercharger as early as 1885.A few years later, Louis Renault, the father of the car brand of the same name, received a patent for a similar design for an internal combustion engine in 1902. Moreover, the Roots brothers invented the device for industrial use back in 1859.
Around the same time, the experiments with a turbine powered by exhaust gases were staged by the Swiss Alfred Buchi. It is he who is credited with creating a turbocharging that functions on this principle in 1905. True, it is now difficult to establish the true first inventor, because Buchi only received a patent.
The world fame of mechanical superchargers was brought by Mercedes-Benz, which began to install supercharged compressors at the end of the 20s, first on racing cars, and starting from the 30s on production cars.
From Germany, the fashion for supercharged cars spread to Hollywood, and from there to the whole world. The golden age of German “compressors” ended at the same time as the outbreak of World War II. The main use of compressors in wartime was in aviation: pressurization was used to compensate for the lack of oxygen at high altitudes.
Immediately after World War II, the use of compressors continued mainly on Formula 1 engines. Car manufacturers were afraid of turbocharging on civilian cars because of the detonation of increased pressure and temperature. Bearing manufacturing technology left much to be desired, cooling and lubrication was also ineffective, which quickly caused turbines to deteriorate.
Finally and irrevocably on the path of “turbinification” world manufacturers have embarked on the fuel crisis of the late 70s.
Without going into technical details, let’s say that mechanical superchargers can be considered part of the evolutionary path, and as a result, turbochargers became widespread. To spin up the supercharger, power from the engine shaft is required, while the turbine spins up simply due to the exhaust gases. The first way is technically more difficult and more expensive in mass production.
Nevertheless, mechanical compressors are still being installed! On the one hand, these are premium models of British Jaguar and Land Rover, some engines from Mercedes, and on the other, traditional muscle cars in the spirit of the Dodge Challenger Hellcat, which continue to specifically “squeal” precisely because of their mechanical supercharger.
The main advantage of this design is that the drive compressor of any design, being tied to the crankshaft, has no inertia. The pedal connection is direct with it, and the acceleration remains even in almost the entire range.
As they say, to each his own. But back to mass-produced cars.
If both types of engines are sold on the market, then each has a number of undeniable advantages. Let’s consider them.
- easier to maintain;
- has a higher resource;
- less oil consumption;
- low requirements for the quality of fuel and oil.
- high power and increased torque with equal engine displacement;
- lower fuel consumption.
As well as the pros, each of the two types of engines has its drawbacks.
- is heavy;
- with the same volume with a turbo engine, the power is lower;
- reduced dynamics – in comparison with a turbo engine of the same volume;
- difficulties when driving in the mountains.
Most of the disadvantages of a naturally aspirated engine surface when compared to turbocharged units. Separately, it is worth mentioning the last point: the air in the mountains is too rarefied, its quantity is not enough for the stable operation of the engine, therefore the engine simply “suffocates”.
- high requirements for the quality of lubricants and fuel;
- expensive repairs;
- long warm-up in winter;
- shorter oil change interval.
Difficulties of choice
Motorists who doubt which engine is better and more profitable cannot be given a definite answer. For example, for connoisseurs of power and dynamics, it makes sense to take a closer look at a turbocharged engine. However, it also entails significant spending on the purchase of high quality gasoline and oil.
The atmospheric engine is notable for its simplicity and unpretentiousness, it can perfectly serve for more than one decade, in addition, even a person with low income can support its performance.
What kind of oil do turbo engines need and what kind of oil is atmospheric?
The turbo engine has the greatest efficiency, that is, the maximum heat production falls on the speed range in the region of 3000-4000 rpm, when the turbine supplies an increased amount of air to the cylinders. After the exhaust gas flow becomes sufficient for the full operation of the turbine, a jump in the generated energy occurs, accompanied by a jump in temperature.
Under such conditions, engine oil must retain its properties at both low and high temperatures.In the case of a turbocharged engine, this is especially important, since the axle on which the turbine and pump wheels of the turbocharger are mounted runs in sleeve bearings. If the lubricant does not provide the necessary protection for this unit, the turbine can prematurely fail without depleting its resource, which is usually 30–70% of the engine’s resource.
For machines with turbochargers, synthetic oils are best suited, as they resist oxidation better than mineral and semi-synthetic oils.In addition, their viscosity is less dependent on temperature changes, which is necessary to ensure the protection of the turbine bearings at all engine operating modes.
As for the characteristics of the viscosity of the engine oil, turbocharged engines “prefer” all-season oils with a low-temperature viscosity index SAE 0W and high-temperature SAE from 20 to 40. Engine oils with a low high-temperature viscosity should be chosen to improve fuel efficiency, high performance viscosity – for better engine and turbine protection.In any case, the selection of lubricant should be carried out in full accordance with the operating manual for a particular vehicle.
In addition, there are a couple of important nuances regarding the use of cars with turbocharged engines:
it is important to constantly monitor the condition of the oil, changing it at the frequency recommended by the manufacturer;
it is necessary to regularly check the air filter – if it is clogged, this will disrupt the operation of the compressor;
the turbine wears out faster if the engine is turned off immediately after stopping the car.To extend the life of the turbo engine, it needs to be allowed to idle a bit to cool the turbine.
Atmospheric engines , in contrast to turbocharged ones, are less demanding on the specific characteristics of the oil. In this case, the general recommendations that we gave in one of the previous articles are suitable.
Just a reminder that we offer an easy way to find the right oil – use our convenient online picker. Just set the parameters “type of equipment – make – model” or use the search bar, and you will be offered all suitable types of oil in accordance with international standards and automakers’ approvals.
The choice, as always, is yours!
Why is your internet connection so slow?
Regardless of the speed of your Internet connection, sometimes some of the bypassing processes will slow down. This article describes possible issues, how to troubleshoot them, and how to get the most out of your Internet connection.
has a built-in troubleshooter that can automatically find and fix some common connection problems.
Open it by clicking the Start button and pressing the Control Panel button. In the search box, type troubleshoot and select Troubleshoot . Under Network and Internet , click Connect to the Internet .
Connection type is set to
The type of Internet connection is the most important factor in determining the speed of your connection.The three most common ways to connect to the Internet at home are dial-up, DSL, and cable. If you have a choice, keep in mind that cable is the fastest and that dial-up speeds are inferior to both DSL and cable.
Many ISPs also offer Optical Optical Optical Service (FiOS), which connects to the Internet via an optical network. In the home, computers are still connected using copper wires.FiOS has the advantage of being faster than traditional copper (DSL or cable) connections. Some ISPs offer several options depending on what area you are in. More populated areas are more likely to be available in FiOS. For more information, contact your telephone company or Internet service provider.
There are several ways to optimize your Internet connection speed.First, you should choose the fastest possible modem. The fastest modem can send and receive data at 56 kbps (kilobits per second). This speed will not be constant, but with a good telephone line, you can count on 45-50 kbps.
Second, make sure the telephone line is in good condition. If the telephone wires in your home or office are old and worn out, interference may occur or conversations on other telephone lines may overlap.This slows down the speed of your Internet connection because the modem is forced to send the same data over and over again until it can be transmitted smoothly. Make sure the telephone wires are not damaged, frayed, or tangled with power cables or other telephone wires. If you hear a crackling sound while talking on the phone, you may need to contact your service provider to check the lines inside and outside your home to make sure they are not damaged.
Tips for users of wireless networks
When connected to a wireless (Wi-Fi) network, the speed of your Internet connection depends on both the location of your computer and whether other wireless devices are in the same area.Wireless networks operate at frequencies similar to those used by other devices, such as microwave ovens and cordless phones. Using a 2.4 GHz cordless phone near a laptop that is also receiving a 2.4 GHz signal may cause interference and even block the wireless network connection completely. To make phone calls while browsing the Internet, use a wired phone or a cordless phone that operates on a different frequency from your wireless network.
The location of the wireless access point or router, or physical access, can affect the quality of your Internet connection. To improve the speed of your connection, move it closer to the access point and make sure there is no physical interference between the access point and the computer.
Computer problems: spyware, viruses and other programs
The state of your computer can affect your Internet connection.Spyware and viruses are undoubtedly causing problems, but add-ons, the amount of memory on your computer, disk space and health, and programs that are running can also affect your Internet connection speed.
Spyware and viruses are one of the most common causes of poor Internet performance. Spyware can slow down your system by interfering with your browser and taking away all your Internet connection resources.Spyware monitors Internet usage and keystrokes, further slowing down performance. The problem is compounded if multiple spyware is running at the same time. If the problem is serious enough, the connection may be lost completely. To maintain optimal performance, you should run your anti-spyware program regularly to remove any spyware.
Computer viruses can also cause poor Internet performance.When it infects a computer, a virus installs computer code that tries to spread, usually by sending copies of itself by e-mail. Some viruses are capable of replicating at a rate of several hundred messages per minute, leaving little to no computing power or Internet bandwidth for other processes. It is quite difficult to detect running viruses, so it is best to keep your antivirus program running all the time.
Browser add-ons also cause performance issues.Browser add-ons are media add-ons, search bars, and other programs commonly displayed in the browser toolbar. Many add-ons enhance your web browsing experience by allowing you to view multimedia content or special document formats. However, some add-ons can slow down your Internet connection. If you think add-ons are causing performance degradation, start Internet Explorer in Add-ons Disabled mode. Add-ins will only be disabled for the current session; however, if this improves performance, you can permanently disable them using the Add-on Manager.To open Add-on Manager from Internet Explorer, click Tools , and then click Configure Add-Ins .
As with all computer programs, Internet Explorer requires a certain amount of processing power, memory, and disk space. Each web page you view is first loaded into memory and then saved to disk in the temporary files folder. Running another program that uses a significant amount of RAM and processing power can consume resources from the browser and lead to delays in its operation.If your Internet connection is slow, close other running programs. If you need to work with several programs at the same time, we recommend increasing the amount of computer memory. Slow performance can also be caused by insufficient disk space. To enlarge it, delete the temporary Internet Explorer files.
Sometimes settings in Internet Explorer change, which can affect Internet Explorer. You can reset Internet Explorer settings to their default values.Resetting Internet Explorer settings is irreversible, so first read the list of settings that will change.
External factors affecting the connection speed
Sorry, there are events and conditions that are out of your control. Even with a high-speed connection, external factors such as busy websites or the spread of computer viruses can slow down the entire network.Popular websites may not be able to keep up with the influx of users. For example, if a site is mentioned in a TV ad, many people might try to access it at the same time. If the website is not ready for this amount of traffic, delays can occur.
During periods of computer virus outbreaks, the Internet may slow down. Many viruses spread, causing computers to send out hundreds or even thousands of copies of the virus. At the same time, the speed of the Internet can slow down due to the huge volume of transmitted data.You can find out what major outbreaks are currently occurring on the antivirus vendor’s website or the security website on home websites.
In addition, congestion on the local Internet can result in slower connection speeds. This happens when many people try to connect to the Internet at the same time, most often during peak hours, such as in the afternoons when students are returning from school and surfing the Internet.
If you are using a corporate network, using a shared network and proxy server may affect Internet performance. Many network administrators monitor Internet usage statistics and try to prevent some user activity, such as downloading large files, during peak hours. If you notice that your Internet connection slows down at times, contact your network administrator.
Loss of engine power and throttle response, causes associated with the ignition system
The car does not run, pulls poorly.
It seems that someone is holding it from behind, you press on the “gas” all the way to the floor, and the engine response is sluggish, or the engine generally stalls after pressing the gas pedal. Similar statements are inherent in many motorists who are faced with a drop in the power and throttle response of a car engine. There can be many reasons for this malfunction (carburetor, power system, engine itself, etc.). In this article, we will consider the reasons for the drop in power and throttle response of a carburetor car engine associated with the ignition system.
Almost always, most auto repair shops recommend first eliminating problems with the ignition system, and then getting into the carburetor and other systems. As an example for troubleshooting, let’s take the carburetor engines of front-wheel drive cars VAZ 2108, 2109, 21099 with a contactless ignition system.
The main reasons for the drop in power and throttle response of the carburetor engine of cars VAZ 2108, 2109, 21099 associated with the ignition system
– The ignition timing is set incorrectly
If the ignition is too early, the engine will pick up well on the “low”, but as the acceleration proceeds, the dynamics of the car will deteriorate sharply.Detonation (“fingers knocking”) will be heard when pressing the gas pedal.
Too late ignition, on the contrary, reduces throttle response at low revs and during acceleration, and at medium and heavy loads, the car can drive more or less acceptable. Here, the problem is smoothed out by a rich fuel mixture and the entry into operation of the vacuum and centrifugal ignition timing regulators making the moment earlier.
The ignition timing must be checked and correctly set first (See.”Setting the ignition timing on the engines of cars VAZ 2108, 2109, 21099″). Initially, it can be corrected by rotating the distributor relative to the scale: to the left – the ignition is earlier, to the right – later.
Adjusting the ignition timing by rotating the distributor on the VAZ 21083, 21093, 21099
– Sticking weights or loosening the springs of the centrifugal timing controller in the distributor
The centrifugal regulator makes the ignition earlier when the engine speed increases due to the divergence of the weights held by the springs.In case of sticking of the weights or breakage of the springs, the lead angle will remain the same, and the car engine needs earlier angles to gain power and throttle response. Accordingly, there is no need to expect any improvement in dynamics from the car.
To eliminate the problem, you will have to remove the distributor, remove the centrifugal regulator and replace the weights and springs with new ones. In some cases, simple cleaning of the parts can be dispensed with. See “Centrifugal ignition timing controller for VAZ 2108, 2109, 21099”.

– The tube for supplying vacuum to the vacuum ignition timing controller in the distributor
has flown off or is not sealed
The vacuum ignition timing regulator also makes the ignition a little earlier at power modes in order to increase the greater efficiency of the engine. For example, if the car does not pull well uphill, then one of the most likely causes will be a failure of the vacuum regulator.
The design of the vacuum regulator must be completely sealed (body, tube). Therefore, first of all, we check the vacuum supply tube, the tightness of its fit on the carburetor fitting and on the vacuum regulator body fitting on the distributor. If the diaphragm is punctured in the regulator body, then it must be replaced with a new one. We also remove the distributor cover and the protective screen and check the fastening and clarity of movement of the regulator thrust. For more details see “Vacuum ignition timing controller for VAZ 2108, 2109, 21099”.

– Faulty spark plugs
Most often, faulty spark plugs give themselves out with pops in the muffler and unstable idling of the car engine. We check the spark plugs by the carbon deposits on the electrodes, the condition of the electrodes themselves, the gap between us. A serviceable candle has brown carbon deposits (different shades are possible). A faulty one will most often be with black carbon deposits or oily.
In addition, by a test with starting the engine in the dark and detecting a glow on the spark plug body, you can check the presence of a “breakdown” of the spark plug insulator.You should also pay attention to the compliance of the spark plugs with this engine (see “Applicability of spark plugs on VAZ engines”). If during the inspection it is not possible to identify a malfunction, then instead of the old candles we install a set of new ones.
Black carbon deposits on spark plugs
– High-voltage wires
The influence of high-voltage wires on the operation of the engine at power modes is enormous, since the failure of at least one of them turns off one cylinder.And what kind of power and throttle response can then be discussed at all. Defective high-voltage wires (armored wires) most often give themselves away by unstable engine idling and misfiring (pops in the muffler). It’s not always true. Therefore, it is best to check them with a tester (see “Checking high-voltage wires”). But first of all, of course, it is necessary to visually inspect them (contamination, cracks, the condition of the contacts and protective tips) and a “breakdown” test with starting the engine in the dark and checking the glow on the wires.
Checking the central core of the high-voltage wire
– Defective switch
Complete failure of the switch will make it impossible to start the engine. In the event of a loss of power and throttle response of the engine of VAZ 2108, 2109, 21099, we are talking about its incorrect operation. In such a situation, only replacing the switch with a known good one can clarify the situation. It is possible to estimate approximately whether the switch is working or not according to the readings of the voltmeter (“Checking the switch of VAZ 2108, 2109, 21099 cars”).

Notes and additions
– The drop in power and throttle response of the car’s engine is also affected by: “punctured” ignition coil cover, slider, distributor cover, Hall sensor. But these malfunctions are manifested, in addition to everything, by the unstable operation of the engine until it stops, a problem with starting, which is not always the case for the main reasons listed above.
– In addition to everything, it is worth checking the base plate in the distributor: its condition (integrity), fastening, the presence of contamination.For more details, see “Malfunctions of the distributor of VAZ 2108, 2109, 21099 cars”.
