What is the service life of modern diesel engines?

Under the engine life, it is customary to understand the number of engine hours that the engine is capable of guaranteed to work. After such a motor resource, the car owner invariably needs to carry out complex overhauls, carrying out a complete restoration of the engine. The service life will depend on various factors, including the driving style of the car and the regularity of the service, as well as the type of engine. According to statistics, diesel engines have a longer service life, which is explained by the peculiarities of their design. However, the car owner needs to take into account the complexity of their maintenance and also keep in mind that it is possible to get cash for cars scarborough.

What affects engine life
Today, the trend in the automotive industry is such that automakers are trying to get as much power as possible from a small engine displacement. This leads to a significant complication of the design, and due to the merciless operation, such an engine wears out quickly, requiring a major restoration. Therefore, a regularity has been established that the smaller the working volume of the engine and the fewer cylinders it has, the lower the motor resource.

Another factor that affects the life of a diesel engine is the presence or absence of a turbine. Supercharging can significantly improve the power of the car, while fuel consumption is reduced, but its presence invariably negatively affects the reliability and resource of the engine. If a naturally aspirated diesel engine, simple in its design, can run about half a million kilometers before overhaul, then a turbocharged engine of the same volume will already have a service life of 200-300 thousand.

The service life of a diesel engine also depends on the quality of the fuel used. Malfunctions of the fuel system invariably affect the general technical condition of the engine, problems with the timing and cylinder-piston group are noted, carbon deposits and burnout of valves appear. Therefore, in no case should you save on fuel quality, you need to refuel exclusively at gas stations of large networks, where they will offer high-quality diesel fuel.

Another prerequisite for a long engine life is the optimum engine operating temperature. If there are any problems in the operation of the cooling system, the load on the diesel invariably increases, which leads to rapid wear of the engine and the need for premature overhaul.

Diesel engine life
There is an opinion among car owners that in terms of reliability and service life, diesel engines are twice as good as gasoline ones. Indeed, such motors are made of more durable alloys, they have greater strength and are capable of running 500,000 without overhaul. However, you need to understand that they will not have a twofold increase in motor resource, especially since the absence of breakdowns in a diesel engine will depend on various factors. On average, such a motor runs about 300 thousand kilometers before repair, after which it needs a complete restoration. Whereas repairs to gasoline engines are usually required on a run of about 200 thousand.

How to increase the resource of the motor
To increase the engine resource, you need to remember that there is no overheating of the power unit, since diesel engines are critical to high temperatures, which can lead to serious malfunctions.

Also, if possible, you need to refuel with high-quality fuel, which eliminates any serious problems with the fuel system and injection. Otherwise, a major restoration of the engine may be required already at a run of about 100 thousand.

A diesel engine is a low-speed engine that produces its peak power at almost minimum speed. You should not spin such motors to the maximum, since this can lead to various kinds of engine malfunctions or its premature wear.

You should also exclude long downtime in traffic jams on the engine, in this case the car does not move, but the engine is started, the number of engine hours increases, and the engine that was operated in this mode may require overhaul even up to 100 thousand kilometers.

You also need to remember about the mandatory service of such engines, and the oil needs to be changed more often than on gasoline engines. Any savings in service will invariably lead to serious breakdowns and a significant reduction in the engine’s service life.
