Resource of diesel internal combustion engine (and how to increase it)

Duster is a compact crossover produced by the French automobile manufacturer Renault. The first copy of the model rolled off the assembly line in 2009 under the Dacia brand. But two years later, the car was rebranded, received the Renault logo and underwent significant changes in appearance. The model is extremely popular among domestic drivers. Affordability, unpretentiousness and resistance to harsh operating conditions are what most attract Russian car enthusiasts.

Now Renault Duster has many competitors, however, the crossover still continues to hold a leading position in its segment. Currently, the car is assembled in India, Romania, Colombia and Russia by the Moscow Renault Automobile Plant. One of the most popular modifications of the car is the all-wheel drive two-liter version of the crossover with an automatic transmission. The share of sales of this configuration in the domestic market is more than 20%. Before purchasing a crossover specially integrated for Russian operation, it is advisable to familiarize yourself with the engine life of a Renault Duster.

How long does a diesel engine last on average?

It is believed that, in general, the service life of a diesel engine exceeds that of a gasoline engine by 2 or more times. After all, for the manufacture of a diesel engine, more durable materials are used that can withstand high temperatures - for example, cast iron instead of aluminum for the cylinder block. In addition, a special feature of the diesel engine is that high torque is achieved at low crankshaft speeds, which ensures less wear on parts.

But such comparisons in favor of diesel engines are correct only for heavy trucks. As for modern diesel engines with a volume of 1.9-2.2 liters in passenger cars, their maintenance-free life is about 300-350 thousand km. mileage This is comparable to the service life of gasoline engines.

The complexity of the fuel equipment of diesel internal combustion engines also directly affects their service life. Moreover, in difficult cases, restoring the normal operation of the fuel injection pump, injectors and plunger pair can cost more than overhauling a gasoline engine.

It is clear that the resource of a diesel engine declared by the manufacturer is designed for its operation in optimal conditions. And the specific mileage at which serious problems will appear is determined by two important factors.

What determines the service life of a diesel engine?

The service life is significantly influenced by the volume of the cylinder, and the larger it is, the more positive it has an effect on increasing the service life of the engine. The condition of the cylinder-piston group also plays a significant role. Operating conditions negatively affect the condition of the rings, since carbon particles and dust that enter with the air cause their abrasive destruction. The upper part of the cylinder is also subject to rapid wear, because it is exposed to gas pressure and the internal rings, while lubrication conditions leave much to be desired, and due to friction the temperature rises.

Of course, the manufacturer must first of all determine what resource a diesel engine has, since it can be different for different cars, and, of course, the more expensive and better the car, the higher it is. In addition, it is of great importance for what purposes the car is used; it is one thing if it takes part in races, and quite another when it comes to a family car purchased for trips out of town.

The engine life depends on the wear of the crankshaft journals, piston group and cylinders.

Design Features

The specifics of design solutions are directly related to the service life of the diesel engine. So, the larger the engine volume , the greater its safety margin, while small cars running on diesel engines have a noticeably shorter lifespan before overhaul.

Another important point is whether the engine is equipped with turbocharging . The latter increases torque and power, but also reduces the engine life of the internal combustion engine. But there are legends about longevity - it is known that they “run” for a million kilometers without serious interventions.

How to increase the resource of an internal combustion engine

As you may have guessed, the service life of the engine depends not only on the material of its manufacture and technical projection characteristics, but also on the driver himself, or more precisely, on the correct maintenance of the power plant.

First of all, the driver must use for lubrication only high-quality oil that has passed special testing and is approved for use on a given type of engine. After all, the lubrication system is the “blood” of any engine and its life depends on its contents.

Oil for a diesel engine must be selected taking into account the applied loads. If you intend to use the engine in conditions close to extreme, it is recommended to fill only with oil with a high viscosity coefficient to avoid its dilution when the temperature rises. The type and brand of oil can also be found out by reading the technical data sheet for the power unit. It indicates all the characteristics of oils used on the engine under various conditions.

Experienced drivers know that a diesel engine is very sensitive to sudden increases in temperature. This phenomenon has a more serious impact than the quality of the oil being poured. To avoid overheating and increase engine power, you can install a turbo compressor connected to an intercooler, which will help maintain the engine at the temperature it needs.

That's probably all you need to know about the service life of a diesel engine. As you can see, the price to pay for a powerful and reliable motor is considerable, because you will have to stock up in advance on expensive spare parts and automotive chemicals that can save you from unnecessary expenses and preserve the life of the motor, even if quite large dust particles have flown into it.

Features of operation

Poor fuel and low-quality lubrication, engine operation under extreme loads and in difficult climatic conditions leads to disruptions in the operation of fuel equipment and deposits of carbon deposits on the walls of the engine, pistons and valves burn out, and the life of the internal combustion engine is reduced by 2-3 times.

The combustion chamber of a diesel internal combustion engine wears out greatly as a result of violations of the temperature regime of the engine. High pressure, friction and extreme temperatures without rapid cooling of parts lead to the destruction of cylinders, wear of timing valves and the need for serious repairs.

"Nissan"

These are Japanese cars, 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. For example, Nissan Note. It is equipped with either a 1.4-liter or 1.6-liter gasoline engine. According to the manufacturer, the resource will be enough for 7-8 years of operation. The figure is 300,000 km. It's not too much.

But the VQ series motors 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 service life of Nissan engines is quite sufficient for most car enthusiasts, especially since the units are manufactured in Japan.

Afterburning catalysts, expensive particulate filters, valves will “live” longer!

Thanks to the combustion catalyst, there are fewer impurities in the exhaust gases. Therefore, the load on the particulate filter and afterburning catalyst drops sharply. Interestingly, afterburning catalysts are able to restore their performance: reducing agents formed during combustion of fuel in the additive clean their surface. During a flash and high-temperature combustion of the air-fuel mixture, the additive cleans the cylinders and exhaust tract, in particular the particulate filter, from soot. Deposits are also removed from the pistons. More information about the positive effect that FuelEXx has on the life of the particulate filter and catalyst can be found here https://www.rvsmaster.ru/Blog/sazha-sazhevyj-filtr-i-katalizator.

FuelEXx extends oil life

The process of incomplete combustion of fuel ends with the formation of deposits. Rings and cylinder liners wear out prematurely. After the rings lie down, some of the unburned fuel enters the engine oil. Oxidation, liquefaction, and then destruction of the lubricant occurs. There are several ways to solve the above problem: premature oil change, use of expensive additives, flushing. But it is much more reasonable to prevent such processes, reduce the amount of carbon deposits in the combustion chamber, and decarbonize the piston rings using FuelEXx. This is much more profitable from a financial point of view.

Instructions for using the additive

The instructions themselves do not look complicated. I just opened the bottle and poured it in. But before that, the internal combustion engine must be prepared.

It is better to change the oil and filter, since the composition is not intended to increase the service life of the lubricant in the engine. And if you replace the old oil on time, you will drain the additive, thereby throwing money down the drain.
Before filling, warm up the engine to operating temperature and turn it off. In a warm engine, the additive will mix better and faster with the oil.
Pour the contents of the bottle into the oil filler neck.
Start it and let it idle for 10-15 minutes.

Here are all the instructions. I will note one nuance that I read on the forum in correspondence with a representative of VMPAUTO.

The question was : Is it possible to pour the additive in -30 frost or is it better to wait?

The answer sounded something like this : You can fill in the additive at any time, but it is best to do this before frost.

VAZ

Cars of this domestic brand used to have a service life of 130 thousand km. But now the situation is gradually changing. AvtoVAZ is releasing new engines that are characterized by smoother and quieter operation.

But still, cars in this segment are economy class, so it’s simply pointless to wait for anything here. In production they are trying to make the design cheaper. Inexpensive materials, assembly, attachments - all this significantly affects durability.

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

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

The figure that reflects the service life of the vehicle is generally not as important as high-quality and regular maintenance of the unit and the vehicle. No matter how high the reliability indicator is, it can easily be reduced by low-quality oil, poor fuel, and improper maintenance. It doesn’t matter at all what the engine’s service life is. It is important to monitor the condition of the units correctly and in a timely manner. and then it will not need repairs in the near future.

Service life of individual parts, operating costs for repairs

FuelEXx fuel combustion additive increases the time between overhauls. In particular, CPG wear is reduced by 50%. This confirms a reduction in acoustic noise by 2−5 dB. In cars running on diesel fuel with the addition of a catalyst, “burning out” of the exhaust pipes occurs much less frequently. And all thanks to a decrease in the temperature in the combustion chamber, complete burnout of the fuel: diesel fuel does not enter the exhaust tract. The duration of correct operation of a diesel engine without major repairs increases by at least 1.3 times

. Other qualities of FuelEXx can be judged by the results of independent examinations.
