Basic Disturbances of Diesel Engines and Their Elimination

Diesel engines operate under conditions of high operating pressure, several times higher than that which occurs in gasoline analogues. That is why for their trouble-free operation, high accuracy of the composition of the mixture, as well as the instant of injection and the quality of spraying are of great importance. Even an uncomplicated repair of a modern diesel engine, at first glance, requires the use of diagnostic equipment, after which bench tests are mandatory. Otherwise, there is a high probability that poor-quality repairs will lead to more serious breakdowns.

Specialists who repair diesel engines say that most often problems arise in the fuel supply systems and its injection into the combustion chambers. Therefore, in the main engines, adjustment or repair of fuel equipment is required. Any diesel-car service should be equipped with a stand for its diagnostics and adjustment. Also in the workshop there should be a diesel compressor and a smoke meter. After the diagnosis, during which any deviations from the norm are detected in the engine operation, the operation of the pumps and injectors is tested, the performance indicators of the fuel injection pump and the rhythm of the fuel supply are taken into account.

As prevention of breakdowns, experts recommend performing a number of simple instructions. First, it is not recommended to work long hours in high-speed modes. Secondly, it is necessary to withstand the intervals of warming up and cooling recommended by the engine manufacturers. Third, do not replace the coolant with water. And, finally, if possible, use only high-quality fuel. Filling in the fuel tank of poor quality, you can get a serious problem - on the injectors and fuel system elements will appear persistent chemical deposits.

The first sign that you have to repair common rail or delphi nozzles will be the fact that the car will dramatically increase fuel consumption. Also, you should pay attention to the engine power, if it decreased - this is the second "bell", another point - the instability of the engine in idle. Noticing one of these signs, do not wait for breakage, and immediately go to the diesel-car service.

Chemical deposits from injectors in car care centers are now being removed in three ways: by washing with the use of a cleaning additive, pouring a washing mixture into the tank, followed by a run through the fuel system, and ultrasonic cleaning.
