Choosing another car, many people are interested in equipment, multimedia system, comfort. The motor resource of the engine is also an important parameter when choosing. What it is? The concept as a whole determines the operating time of the unit until the first overhaul in its life. Often the figure depends on how quickly the crankshaft wears out. But it is written in reference books and encyclopedias.

Engine resource - what is it?

Among motorists, this concept means the time of efficient operation of the motor.

That is, when the unit began to consume more fuel, power decreased, various knocks and other extraneous sounds appeared during operation, the engine began to consume more oil, all this indicates that the engine's motor resource has been exhausted, and it will soon will need a major overhaul in the future.

In order for the motor to work efficiently, the owner is required tocomply with the rules of operation. It is much easier to prevent possible problems in advance than to fix them urgently later.

High-quality engine oil and coolant will help improve the resource. You should also monitor the condition of the air filters. The car must be serviced regularly. It is necessary to prevent non-standard operating modes of the unit.

Diesel engine

When buying a diesel car, I want to know what engine life is. In general, diesels are said to have the highest number of engine hours before the first repair. Many diesels are included in the list of "millionaires".

What does the indicator depend on?

The volume of combustion chambers has a very strong influence on this figure.

And the larger this indicator, the more positively it affects the service life. An important role is played by the condition of the cylinders and pistons. For example, the integrity of the rings is negatively affected by the conditions of use. Carbon deposits and dust can act abrasively on parts and thus destroy them. The upper part of the cylinder also wears out quickly - gases and inner rings press on it, while lubrication may be insufficient.

Naturally, only the manufacturer can determine the service life of a diesel engine. Different cars and different engine models may have different performance. The higher the cost of the motor, the better it is. It is also important for what purposes the machine is used. If cars are raced, this is one thing, but if the carbeing used as a family car is quite different.

Resources of gasoline and diesel engines

It is believed that the engine life of a diesel engine is more than 2 times higher than that of gasoline units. But in practice this is not always confirmed. Naturally, a Japanese gasoline unit will last longer than a similar one, but assembled in China.

But even if we consider equivalent cars with similar engines, the diesel power unit is more resourceful.

Due to what is the resource on diesels higher?

The fact is that more durable materials are chosen as materials for the manufacture of diesel engines. So, the cylinder block is not made of aluminum, but of cast iron. In addition, the strength tolerances are much higher here. The piston group is also manufactured - each part has higher tensile strengths. And such engines will work much longer.

On diesel cars, the number of working revolutions is 1.5 times less than on gasoline ones. At the same time, the number of piston strokes is also reduced and its wear is reduced. The number of revolutions of the piston group and the crankshaft on a diesel engine will be from 1500 to 3000 rpm, while on gasoline this figure will be twice as high.

How to change diesel resource?

You can easily reduce or increase the life of the engine, no matter if it is diesel or gasoline. The number is easily changed using the lubrication system. The quality and properties of the oil largely determine how long and how efficiently the engine will work andthe whole car. Oil plays a rather serious role.

It is very difficult to choose the right lubricant. Each motor is used in different conditions.

Some work under d loads, others work at high temperatures.

It is possible to reduce motor resource with the help of temperature stresses. Thermal overloads affect the operation of the motor even more than pressure. Knowing this, it is possible to increase power with the help of supercharging, while maintaining both the temperature regime and the motor resource.

Renault engine durability

When choosing cars from this manufacturer for many buyers, durability is considered a decisive factor. According to European car owners, the engine life of the Renault engine is about 750,000 km. This figure is the highest among all B-class sedans. Naturally, this figure is relevant only when the car is properly cared for. With proper care, this figure can increase.

If this is a new car, it is important to break it in correctly. Also, do not drive on bad roads, where the engine will work at its limit. It should not be overheated or over-twisted. It is also important to change the timing belt in time - a lot depends on it.

The manufacturer recommends checking the belt every 15 thousand kilometers.

If all the rules for the use of aggregates are observed, their resource is quite high and will be able to give odds to older foreign cars.

Nissan

These are Japanesecars, engines, therefore, also from the Land of the Rising Sun. Japan has always been distinguished by various high-tech developments and solutions. As for car engines, the resource here is not always impressive. Take the Nissan Note, for example. It is equipped with either a 1.4-liter or 1.6-liter gasoline engine. According to the manufacturer, the resource will last for 7-8 years of operation. The figure is 300,000 km. It's not too much.

But the motors of the VQ series from the same manufacturer are considered one of the most reliable.

Thus, the six-cylinder VQ25DE and VQ35DE will confidently cover more than 500 thousand km with proper maintenance. In general, the engine life of Nissan engines is quite sufficient for most motorists, especially since the units are manufactured in Japan.

VAZ

Cars of this domestic brand used to have a resource of 130 thousand km. But now the situation is gradually changing. AvtoVAZ launches new engines, which are distinguished by smoother and quieter operation.

But still, the cars of this segment are economy class, so it's simply pointless to wait for something here. In production, they try to make the design cheaper. Inexpensive materials, assembly, attachments - all this has a significant impact on durability.

But at the same time, the new VAZ engines, whose engine life, according to engineers, is 500 thousand km, work quite well.

Perhaps this figure should bea little less, about 300 thousand, and even then with a quiet driving mode, but this is the result.

The figure that reflects the motor resource is generally not as important as the quality and regular maintenance of the unit and the car. No matter how high the reliability indicator is, it can easily be reduced by low-quality oil, bad fuel, and improper maintenance. It doesn't matter what engine life. It is important to properly and timely monitor the condition of the units. and then he will not need repairs in the near future.
