At what speed to operate the diesel engine. Rules for operating a turbo diesel engine

In the century technological progress and rapid development automotive industry machines are getting more powerful and faster than before, while manufacturers are also focusing on safety and economy. World auto industry for last ten years has stepped far ahead, today offering the consumer a car in various body designs, equipped with innovative systems and units. In the car market, more and more often you can find cars equipped with gasoline and diesel turbocharged engines, which until recently were not so popular and were installed only on sports cars... The slow pace of introduction of motors with turbines into the masses is due to the high price for such models, in addition, many motorists remain faithful to the classic version due to the high degree of reliability.

Now consumers are willingly "trying on" improved technologies, demand is growing, which means that production volumes are also increasing. Motors equipped with turbines are no longer a rarity, they fill the market at a breakneck speed, displacing. At the same time, in pursuit of trends, when purchasing a car with a turbo engine, it is important to understand that in view of design features such a unit needs proper operation and proper care, otherwise it will not please the car owner with durability, without even stretching out the prescribed period.

All engines internal combustion function thanks to the energy generated by combustion air-fuel mixture in the cell. The more air masses are supplied to the cylinders, the more combustible mixture is burned in one cycle, which directly affects the amount of energy released that affects the pistons. The difference between atmospheric and turbocharged types of internal combustion engines is in the method of air supply, and the power units, despite the design differences, can be both gasoline and diesel.

Continuous work has shown that volume is no longer a determining factor in the power, dynamics and torque of the unit. Equipped with artificial air blowers, there is no need to increase the size of the engine. Since atmospheric internal combustion engines, to create a mixture and ensure its ignition in the chamber, take air from the outside in a natural way due to vacuum in the intake manifold, in order to improve performance, it was necessary to significantly increase the volume of power units. By using exhaust gas turbocharging, high performance can be achieved with compact dimensions... Let's take a closer look at what a turbocharged engine means.

The device of such a motor assumes the presence of a turbine or mechanical compressor... The task of the supercharger is to supply the air masses to form the mixture under pressure in the cylinders, which speeds up the combustion processes, contributing to increased torque and power. Initially in the automotive industry, turbines were installed on diesel engines, and it is because of this that diesel engines have ceased to be associated with tractors. Today, diesel turbo engines are included in the most modern models cars from world auto giants. On gasoline internal combustion engines, the use of systems for forced air injection was impractical due to the high cost and reduction. But now, when turbocharged units have moved on to a new round of evolution, the problem has been solved, now supercharged engines are actively used in gasoline versions of units.

Structurally, a motor with an air blower differs from the usual atmospheric internal combustion engine, which provides it with both advantages in the form of increased characteristics with compactness and low weight, and disadvantages. Due to the complexity of the design, the reliability indicators are greatly reduced, therefore, in the wrong operating conditions, the risks of breakdown increase significantly. Unlike unpretentious atmospheric engines, supercharged units require increased attention from the car owner. If the use of or oils does not particularly affect the aspirated, then motors with an air blower are very finicky in this regard. You should not neglect the rules of operation and maintenance, as this can lead to sad consequences.

Advantages and disadvantages of a turbocharged engine

Recently, sales of cars equipped with turbocharged engines have grown significantly. Car enthusiasts were divided into two camps: those who do not recognize the need to install a compressor, in particular in gasoline engines, preferring the classics, and those who love the wind of innovation, believing that it is time for aspirated people to retire. Both are right in their own way, therefore, when deciding on the purchase of a car, you need to carefully weigh all the pros and cons of a turbocharged gasoline engine or diesel, as well as take into account other factors that determine the feasibility of purchasing.

The advantages of turbo engines are obvious:

increased power characteristics with the same volume;
compactness and low weight of the unit;
high torque starting from the lowest rpm, demonstrating stability;
low fuel consumption in relation to power characteristics;
less exhaust volume.

The cons of turbocharged engines are as follows:

when driving at high speed, fuel consumption is increased;
the need to warm up the engine in cold weather;
the presence of "turbo" (the phenomenon of power failure at hard pressing on the gas pedal is typical for old unit designs);
strong heating;
high cost of repair;
sensitivity to fuels and lubricants low quality, as a consequence, the dependence of the resource on the funds used;
frequency of oil change, as well as oil and air filters more often than aspirated;
high maintenance costs due to the need to use only high quality working fluids.

For many drivers, the disadvantages of turbocharged engines far outweigh the advantages. Especially frightening are the costs and the need for constant monitoring of the condition, as well as scrupulousness in care, which is associated with the complexity of the unit design. The reliability of aspirated air is no longer questioned, whereas in the case of supercharged engines, the resource entirely depends on the owner.

Resource of turbocharged engines

The features of care and finickyness of motors with artificial air blowers are directly related to the complexity of the design. The basics of turbocharging, one of the exhaust gas charging methods, reveal how the engine works:

air enters the turbocharger inlet through the air filter;
air masses are compressed, while the level of oxygen saturation increases, the process also involves heating the air, and its density decreases;
from the compressor, the air flows pass into the intercooler, where they are cooled, acquiring the same temperature, the intercooler also provides a decrease in the predisposition to detonation of the air-fuel mixture;
air masses pass through the throttle, passing to intake manifold, and at the exhaust stroke they fall into the cylinders of the turbo engine;
after ignition of the mixture, combustion residues fall into the exhaust manifold. Passing through the turbine, the hot gas flow drives the shaft, on back side which the compressor is located. Thus, the next batch of air is compressed.

The amount of oxygen with which the chamber is filled is significantly greater than with natural air intake, therefore, a larger amount of the mixture is burned per cycle, which entails an increase in power characteristics.

The service life of the turbine is slightly less than the wear resistance of the motor itself, while proper care of the unit and its components is assumed. The main enemies turbocharged enginesignificantly reducing the resource:

low quality engine oil;
low grade fuel;
oil starvation;
increased loads "on the cold";
untimely replacement of oil, oil and air filters.

Frequent scheduled maintenance and constant monitoring of the oil level and the quality of the materials used can significantly extend the resource. This is not to say that anything can be poured into the aspirated engines, but still they are less susceptible to the influence of these factors, and if oil or low quality fuel gets into the engine, then there will be no disastrous consequences, as in the case of a turbocharged unit. Unlike atmospheric motors, the turbo engine makes the most of its potential, therefore it is more prone to wear and tear. The resource of a turbocharged engine can reach 150-200 thousand km. run, but subject to proper care, while atmospheric-type engines, characterized by their simplicity of design, cover all 300,000 km. Failure to comply with the manufacturer's recommendations can reduce the resource by at least half.

There are many nuances in servicing turbocharged engines that must be taken into account during operation if there is a desire to extend the life of the engine and turbine:

An engine that is constantly pushing its limits will wear out quickly, so you shouldn't constantly flush the gas pedal unless you are a racing driver. In addition, aggressive driving increases fuel consumption. To extend the life of the engine, drive a turbocharged car in a moderate mode.
It is important to observe the engine oil change intervals and in no case should oil starvation... The intervals can be significantly reduced due to difficult operating conditions. When changing the oil, the filters must also be changed.
In the case of turbocharging, savings on lubricants inappropriate, because it can subsequently lead to more significant waste on repairs. It is necessary to use oils recommended by the manufacturer of the unit, not using analogues and not mixing different grades.
It is also necessary to use high-quality fuel, since low-grade fuel contains various impurities and clogs the fuel system, reducing the resource.
During operation in cold weather, it is recommended to first let the unit run for idleto circulate the lubricant. In particular, this rule should not be neglected in the case of a diesel engine.
When starting the engine, do not hold the gas pedal for a long time, as this will force the turbine to idle, which reduces its resource. This is due to the fact that in supercharged units high pressure provided already at low revs.
Do not suddenly turn off the diesel and gas engine supercharged. The engine needs some time (even a couple of minutes is enough) to hold idling, this will ensure a uniform decrease in temperature, since on high revs it rises to the maximum. A sudden shutdown provokes a temperature drop, which entails heavy wear turbines, why it is impossible to immediately turn off the turbocharged engine. For this reason, some models have a turbo timer that controls the process; it turns off the engine after a time after the ignition is turned off.

Having figured out how to properly operate a car with a motor equipped with a turbine, and take care of it, you also need to get used to the control features, then there will be no difficulties in maintenance, and the risks of breakdown will be minimized. Proper care and adherence to the rules of operation will significantly extend the life of the heart of the car.

Mas Motors

Diesel power units represent a fundamentally different design than their gasoline counterparts. The key difference lies in the technology of preparation and ignition of the fuel. The formation of the mixture is carried out in the combustion chamber, and the cycle of work consists in injecting a metered portion under enormous pressure, after which it ignites upon contact with heated air. This technology allows you to get rid of the gas pump, spark plugs, high-voltage wires and other elements necessary for gasoline engines.

Benefits

Diesel powertrains share a number of common advantages.

Profitability. The efficiency of such motors is 40% and can reach 50% with a pressurization system.
Power. During operation diesel engines with the turbine, the classic pronounced turbo lag is not observed, and all the torque becomes available from almost the lowest rpm.
Reliability. The diesel power units have a mileage of up to 700,000 km.
Environmental friendliness. The use of EGR technology and a significantly lower amount of CO in the exhaust gases can significantly reduce the negative impact on the environment.

Refueling

One of the features of the operation of diesel engines of any type is meticulous attention to fuel quality. Experts advise you to check on your own even fuel from branded gas stations.

The main enemy diesel installation - this is the presence of water in the mixture, which is capable of provoking corrosion in the fuel equipment. To avoid this, it is recommended not to refuel the fuel directly into the tank, but to fill it in canisters and let it settle so that possible sediment and impurities have time to sink to the bottom.

A simple way to test the mixture for water is to add potassium permanganate crystals to a test portion collected in a transparent bowl. If water is present, colored streaks will immediately form around them.

Another important criterion is the absolute transparency of the mixture. Any turbidity, especially in winter period, can mean the initial stage of paraffin crystallization, which easily clogs fuel filters.

Service

The specifics of the operation of diesel engines implies scrupulous fulfillment of all manufacturer's requirements, any violation of which may ultimately lead to the need for expensive repairs. Recommendations common to all power plants of this type, relate:

Timely oil change and quality control. Experts advise to carry out this procedure even more often than the service interval prescribed in the manual. This recommendation is related to the unstable characteristics of the sulfur content of Russian diesel fuel. As a conditional interval, you can focus on a mileage of 7000 km? 7500 km.
Timely replacement of the timing belt. In this case, it is recommended to follow the same principle as when changing the oil. For many motors, the permissible belt mileage reaches 100,000 km, however, it must be borne in mind that we are talking about practically sterile conditions that are fundamentally unattainable on domestic roads... The breakage of a belt worn out prematurely always means the destruction of the block head, the repair or replacement of which is costly.
Fuel system cleanliness control. It is recommended to replace the filter at least every 10,000 km, and from the filter itself - regularly drain the sediment accumulating in the sump. It is advisable to flush the fuel tank twice a year by removing it from the vehicle. Failure to comply with these requirements can lead to damage to the injectors and the fuel pump.

Ride features

Warming up and stopping the engine. The issue of driving "cold" is debatable. The operation of diesel engines allows this possibility, but it should be borne in mind that thermal clearances at this moment they are increased, and the cooled oil, on the contrary, partially loses its lubricating properties, which in combination leads to increased wear of parts. The best solution would be to drive at speeds up to 40 km / h with the 3rd or 2nd gear engaged. It is possible to turn off a non-turbocharged engine immediately, but a motor equipped with a pressurization system must be given the opportunity to run without load so that the bearings have time to cool down and are not covered with a varnish film.

Optimal RPM. Power units of this type are low-speed. The habit of "turning" the engine above 3,500 rpm - 4,000 rpm leads to accelerated wear of the cylinder-piston group and the crank mechanism. The optimum range for these motors is, depending on the model, between 1600 rpm and 3200 rpm.

Specificity air filter. Diesel units are not provided with throttling at the inlet, which, in combination with the small volume of the combustion chamber and high suction properties, provokes a water hammer when even a minimum amount of water enters the filter.

Refusal to start "with thrust". A properly working power unit starts up normally at a temperature environment up to? 20 ° C. If it is difficult to start, it is strictly forbidden to try to "jerk" the car, as this may damage the timing drive. In addition, a mismatch between the temperature tolerance of the fuel and the temperature overboard leads to crystallization of wax and the loss of the required fluidity by the fuel. In such a case, attempting to start the engine in tow will result in dry friction and damage to parts. power unit.

Operation in winter

Operation of diesel engines in cold weather is complicated by the need to use the appropriate fuel when the temperature drops to 20 ° C or more ("winter" and "arctic", respectively). The condition of the injectors and the high-pressure fuel pump requires special attention. At this time, experts advise leaving the car overnight in a warm garage to avoid the crystallization of paraffins in the combustible mixture. In the case of a diesel engine equipped with a turbine, it is very useful to have a turbo timer, which will allow it to withstand the intervals necessary for heating and cooling.

Attempting to save on parts or maintenance while operating a diesel engine can result in costly repairs. Due to significant loads, strict requirements are imposed on the quality of components of this type of power plants.

Using cheap candles, chains and other accessories can turn into a waste of money, as parts will fail in no time.

A similar principle is relevant for the service itself, in which renovation work... Hiring unskilled mechanics can result in loss of time, money and even new engine damage.

Diesel repair requires strict adherence to the work schedule and the availability of professional knowledge and equipment from the performers.

Diesel center "Diesel-PRO" is a representative of the largest brands of auto components, and also offers services for the adjustment and repair of fuel equipment of domestic and foreign production. You can find the required diesel engine, as well as familiarize yourself with the characteristics and photos of the goods in the catalog on the company's website.

Each driver has their own considerations as to which powertrain is actually better. Some believe that the small volume brings a big advantage and provides fuel economy. Others believe that it is worth buying only a gasoline engine because of its unpretentiousness and versatile operation. Still others choose only voluminous diesels with a turbine for immense pleasure from excellent traction. Let's figure out how to operate a diesel power unit, which has a number of features of use. Correct use can significantly extend the life of the unit and provide many important benefits. If you switch from a gasoline SUV to a diesel one without changing your habits, then your power unit will have a difficult time.

Engine use is a topic that can be discussed endlessly. Based on what features of the trip are violated by the owners of the equipment in comparison with the factory recommendations, it is very easy to find a number of important recommendations. This question concerns the filling of certain fuel and oil filling, serviceas well as renovation. There are certain practical tips for reducing consumption and wear on a diesel engine. You can also remember winter use diesel engine that should be very tidy. Considering all the categories presented, we can form several important tips for owners of diesel power units. One has only to say that everything said below refers to modern turbocharged diesel engines that are installed on mass passenger cars.

Refueling and maintenance are the two most important points of use

First of all, when buying a diesel power unit, you need to choose a normal refueling place. We are talking not only about the quality brand of the filling station, but also about the quality of diesel fuel, which does not always coincide. Use the recommendations of experts and check the quality of diesel fuel using simple tests. Fuel must not freeze, cloudy and must be clean in all conditions. It is also worth following the recommendations for maintenance:

for a diesel power unit, many manufacturers set a slightly shorter service interval than for gasoline engines, but this is not always the case;
you need to fully comply with all the conditions of service that are set by the car manufacturer, use only original materials at the service;
when buying an unknown oil, you can say goodbye to the engine after 10-20 thousand kilometers, filters are also worth buying original and very high quality;
special attention should be paid to equipment diagnostics during the service - this will help to avoid the most unpleasant problems associated with the high-pressure fuel pump and the block head;
it is necessary to repair the diesel engine immediately after the car has shown a problem, this will help to maintain a certain quality and desired properties of the installation.

If a gasoline engine is sometimes operated successfully and with malfunctions, then this idea will not work in diesel power units. You need to use the services of a professional service for maintenance Common rail, turbine, injection pump and cylinder head. It is these parts that most often fail and cause certain troubles during operation. A breakdown can completely destroy the unit.

How to drive a modern turbine diesel engine?

Current heavy fuel powertrains do not differ too much from gasoline engines. The issue of the quality of the trip can be very serious because correct operation leads to a number of problems. You need to remember the basic recommendations, as well as read the features and individual tips in the operating instructions for your car. The basic recommendations for such engines are as follows:

use high torque at low rpm - do not spin the diesel engine to high rpm of the power unit;
take advantage of the convenient early gear changes and the excellent traction characteristics of the diesel vehicle, this will help to get comfort;
do not overheat the unit, long work at high revs or off-road operation in the middle mode disables the injection pump and other important modules;
don't drive a diesel car - you buy a car for comfort and low flow, so use all the important advantages of transport with such traits;
in the city, it is quite possible to drive at a speed of 60-70 kilometers per hour using the last gear - this is one of the favorite modes of operation of a diesel unit.

You need to understand that diesel has a completely different structure than the usual gasoline engine. There are a number of advantages, but there are also disadvantages. Therefore, you should always study the manufacturer's recommendations for using the car, otherwise you can get into an unpleasant situation. Use the highest quality travel solutions and always strive to comply with factory recommendations. This will help keep your machine running.

What are the important advantages of a diesel engine?

The diesel-type power unit is known for eating less fuelthan a petrol counterpart with similar power characteristics. This is true, but the diesel-type power unit is one of the spendthrift budget on the service, it requires more money to complete all the tasks. Therefore, it is worth highlighting such clean and undeniable advantages of a heavy fuel power unit:

the possibility of early gear shifting, very good torque, which picks up the gearbox in any mode and rides perfectly even in an unsuccessfully selected position;
very high traction indicators directly in the acceleration process, that is, at low speeds, the highest indicator of the optimal useful power of the unit appears;
reduced fuel consumption compared to gasoline evens out the cost of operating a power unit on heavy fuel, so that it will not cost you much more;
the service life of the diesel engine, subject to all important recommendations, will be quite high, there are no problems with the device, many drive up to 500,000 km;
the environmental cleanliness of emissions is much better than that of gasoline options, there is no carbon monoxide, but there are solid particles, and they often exceed the norm for a car of this class.

Today's powertrain designs are becoming more sophisticated and demanding. Therefore, you should carefully follow each update and study the engine, information and reviews about it before buying. One and the same unit in different generations cars from the manufacturer can have completely different options for use. And in this case, you can get really disappointed when buying.

How to operate a diesel engine in winter?

The winter operation of a diesel-powered power unit is somewhat more complicated. If gasoline does not freeze at all, in principle, the cloud point of diesel fuel is -25 degrees Celsius. The freezing temperature already at -35 degrees excludes the operation of a car in such conditions. However, today there is diesel fuel with additives, which is used without problems in any conditions. There are a number of cautious points:

in winter, it would be nice to install a turbo timer in a diesel engine, which would continue to slowly reduce the engine temperature after a trip, when you have already left the car;
should also choose winter fuel at a gas station, having chosen initially normal gas station, on which you will not fill the tank with low-quality liquid;
you can also use a number of additives to reduce the crystallization temperature of the fuel when the fuel poured into the tank turns into a gelatinous mass;
after the diesel fuel turns into gel, you will have to take the car to service, and on a tow truck to clean fuel cells and hoses for future use.

For these reasons diesel cars in northern conditions - this is not the best option. In central Russia, such cars are quite acceptable and can perform their functions perfectly. In the south, there are no problems with their operation at all. Nevertheless, you need to take into account a number of features for the use of fuel and the quality of service for your car. We offer you to watch a short video about the features of a diesel car:

Summing up

Does it make sense to buy a diesel car? In economic terms, this makes little sense. But in terms of travel, your conditions will really change dramatically. You will get to know new technologythat completely opens up a new perception road transport... There are a number of positive and a number of negative factors in the use of such transport. But diesel lovers often argue that the pros far outweigh the cons. Of course, all this is very arbitrary. You can buy a diesel engine and be extremely unhappy with the situation during the first breakdown in winter. But remember that the quality of operation directly depends on you.

You should also remember about the dressing, which can be normal and terrible. If a gasoline unit from bad refueling will simply increase the consumption, then diesel fuel can destroy a number of expensive items in the car. Therefore, in Europe, for example, to exploit diesel units unproblematic. On the other hand, there are always a number of difficulties in owning a car with such a unit. So if you are afraid of these difficulties, it is better to choose a gasoline car. If you want to try something new, feel free to buy a turbodiesel. Which engine would you prefer for personal use?

For many car enthusiasts, buying a car with a turbocharged engine is a dream come true. But here we are talking about a special design of the intake and lubrication system, so the lucky owner should pay more attention to his " iron horse»And use it correctly. Otherwise, turbo engine malfunctions will become a very common occurrence and spoil a lot of nerves for a motorist. In this article, we present six useful recommendationsthat will help you make the most of the turbocharged engine's capabilities and avoid breakdowns.

Watch your filters

Always keep the oil and air filter of the vehicle under control. For such an engine, these points are especially important. In addition, when replacing, it is necessary to strictly follow the manufacturer's requirements and install only parts of recommended brands.

Monitoring the lubrication system

When it comes to repairing your car's turbine, the first step is to check the condition of the oil and grease. There should not be any extra impurities in the composition. It is advisable to check the crankshaft with the engine off. If everything is normal here, then you need to start the engine and let it run for a few minutes, listening carefully to the noise. It is important to ensure that the turbine bearings and lubrication system are working properly.

Correct start of the turbocharged engine

Requires special attention turbocharged engine start... Here, the car enthusiast is highly discouraged from getting carried away with gas filling. It is advisable to let the engine run for some time (at least one to two minutes). Of course, a turbo engine to achieve the right pressure just a few seconds is enough, but this time is clearly not enough for all the engine elements to be well lubricated.

If the turbine runs for at least a few seconds without proper lubrication at high speeds (if the gas pedal is pressed immediately after starting), it can easily fail. IN best case its service life will simply decrease.

Stopping a turbocharged engine correctly

It is also necessary to jam it wisely. Before turning off the ignition, it is necessary to let the engine cool down at least a little, which at maximum loads has to work in peak temperatures. If you turn off the ignition immediately, this can lead to a sharp temperature drop, and, therefore, to a reduction in the life of the turbocharger. Very often, the latter fails precisely for the reason misuse... Here why can't you turn off the turbocharged engine immediately after stopping the car

Operation of the turbo engine at low temperatures

The turbocharged engine must be started correctly when low temperatures... If you often have to operate a car in cold weather, then you need to make it a rule to first turn the engine slightly, and then start at idle speed. In this case, the oil will circulate normally and gradually fill the system. Overloads during such a start will be minimized.

Start of movement

Never start driving a car with a turbocharged engine until the latter has been idling for at least a couple of minutes. But here you need to know when to stop. In idle mode, the engine should run no more than half an hour. Otherwise, leaks may occur in the most weak points connections due to so-called low pressure generation. Yes and

Today we will touch on a very relevant topic: proper engine operation.

After all, it's not a secret for anyone that one of the most expensive repairs in a car is engine repair.

And from how much the owner approaches its operation correctly vehicle will depend on how often his wallet gets rid of banknotes.

Comparing an engine in a car with a human heart is not an exaggeration at all. It is the engine that takes over the main functions and creates the tractive effort of the vehicle.

Malfunctions and failures in the operation of the power unit inevitably lead to more serious problems, and sometimes complete immobilization of the car.

So how do you properly operate your engine? What points should you pay attention to?

Let's figure it out.

The reliability and resource of the engine depends on many factors, namely on the operating conditions, quality engine oil and fuel mixture, air purification and so on. At the same time, there is no recipe for the "immortality" of the motor. There are only recommendations to significantly extend its life.

So, follow these tips when operating the engine.

Oils

Pour into the power unit only quality oil, monitor its level and replace it in a timely manner.

When choosing a lubricant, pay attention to its type and viscosity index.

For instance, a good option - synthetic or semi-synthetic oil 10W40.

Do not forget to pay attention to the purpose of the oil. If it can only be poured into a diesel engine, then the word "diesel" will flaunt on the label.

Fuel

Remember about the low quality of gasoline (diesel fuel) at gas stations and promptly change fuel filter, don't forget about.

Drain off accumulated sludge from time to time. If this is not done, then the whole fuel system due to the high hydraulic resistance.

The ideal option is to remove the fuel container at least twice a year and clean it thoroughly.

Timing belt

Inspect the timing belt from time to time and replace it in a timely manner.

Even if the belt works like a clock, change it mercilessly after 60 thousand kilometers.

Otherwise, you risk your engine and even more costs.

Spare parts

Buy only quality parts. Do not save on your car and try to install only original parts.

Firstly, this increases the engine resource, and secondly, it frees you from additional costs in the future, because a poor-quality unit can "pull" other parts along with it or it will fail ahead of time.

Warming up the car

In addition, do not allow the rpm to rise above four thousand. Such a load negatively affects the engine and reduces its resource.

How to ride

Avoid puddles, if possible, or drive through them at minimum speed. If you "fly" into the water, then there is a high risk of water hammer.

And for the chassis, such a driving style will be very harmful, because you do not know how deep this puddle is, so there is a high probability of being left without wheels at all.

be careful

Pay maximum attention to the engine. Always check the oil and coolant levels before starting the engine. When doing this, never add cold coolant to a hot system.

Please note that the temperature difference should be no more than 15 degrees Celsius. Pay particular attention to the tightness of all systems.

When starting a car with an injector, do not press the gas pedal. Fuel is pumped up automatically here.
To dry the candles, just open the throttle and turn the crankshaft.
Do not allow the fuel tank to be completely emptied, otherwise the injector may fail.
Monitor the condition and charge level of the battery. Low voltage can damage an expensive system.

Secrets of operating a diesel engine

The above tips apply equally to both gasoline and diesel engines. But there are still some features.

For instance, diesel cars require more attention from motorists (especially in winter).

When operating a diesel engine in winter, consider a few simple tips.

Danger of starting from a tug

Do not start the vehicle from the tug as this could damage the engine.

For example, if summer diesel fuel is poured into the tank, and the outside temperature is subzero, then starting the engine is unlikely to be successful.

Diesel fuel already at five degrees of frost turns into crystals, and the fuel itself loses its main property - fluidity.

In diesel engines, fuel plays the role of lubricant, and if there is no full lubricant, then the units operate “dry”. The result is serious damage.

Therefore, follow the correct one.

Batteries

Pay attention to the power source. Diesel engines due to a greater extent compressions need a powerful battery. That is why batteries with a starting current of at least 320 A are recommended for diesel engines.

In addition, it is better to replace a power source that has served more than 3 years. At the same time, you should also not throw it away - give (sell) the battery to the owner of a car with a gasoline engine.

Pay special attention to the condition of the terminals on the starter and battery - they must be cleaned.

With a decrease in temperature, the capacity of the battery decreases, so additional resistance will only worsen the situation.

The ideal option is to grease the terminals with a special plastic compound that will protect the metal from the appearance of plaque and salt on winter roads.

Watch your exhaust

If in the summer at work diesel engine obvious smoke was noticeable, then check the fuel injection advance angle.

In the absence of adjustment skills, it is better not to take risks and turn to professionals.

Take off excess

A special mesh from the intake (it is installed in fuel tank) better to remove. Practice has shown that this particular grid - main reason the appearance of traffic jams and problems with starting the motor.

This grid has stopped completely letting fuel through.

Choose the right oil

Cars with a mileage of more than 100 thousand kilometers often suffer from a decline.

The reason is excessive wear on the cylinder liner and piston rings... That is why when the temperature drops below 25 degrees Celsius, it is better to give preference to oil with a reduced viscosity.

Therefore, you need to be able to distinguish.

Check glow plugs

For a diesel engine, difficulties begin already at 5 degrees Celsius and below. Prior to this, the engine can still be started without working glow plugs.

With a greater cold snap, one faulty spark plug is enough for an unsuccessful start.

To avoid problems in the cold, diagnose glow plugs before winter. Replace if necessary.

Secrets of operating an engine with a turbine

The presence of a turbine is not only agility and excellent engine dynamics, but also a great responsibility for the car owner.

Cars with a turbine require special care from a car enthusiast.

For example, there are more stringent requirements for oil quality. The correct choice of the lubricant composition can increase the service life by at least two times.

Another important point - timely check and replacement of filters (oil and air).

But that's not all.

To extend the life of a turbocharged engine, follow these guidelines:

after starting the engine, let it warm up for a minute. Sure, operating pressure in the system, it is achieved in 2-3 seconds, but more time is needed to accelerate the moving elements of the turbine. If you immediately give gas to an engine that has just started, then after a few years, or even months, you can say goodbye to the turbocharger. The reason is that the unit simply does not have time to lubricate and rotates "dry";
after leaving by car in active mode, try not to turn off the engine immediately after stopping. Let it run for a while (3-5 minutes). This allows you to minimize sudden temperature changes in the engine and eliminate destructive transients;
