When you need to repair injectors?

Often the atomizer are needed in case of premature wear or contamination. And it happens because of the poor quality of diesel fuel that contains substances like sulfur, dirt and even water. The last substance greatly affects the wear of the injectors. The thing is that after stopping the motor the water contained in the diesel fuel accumulates at the nozzle. And if the car does not make movement for several days (maybe even hours), the mechanism of the injector starts to rust. On its surface rust, as a result begin to break down all the elements of this mechanism, including a needle and a sealing washer. After some time there are leaks of diesel fuel, and failure of the atomizer. It is possible to detect the color of the exhaust (usually from the muffler belching grey-black smoke) and excessively high fuel consumption. It could also indicate improper operation of the fuel system.

Characterization and repair of Common Rail injectors

This atomizer is the most popular and most durable among all available today. After cleaning, it can operate for another 100-200 thousand kilometers. How is the repair of nozzles of this brand?

Injection pump and many other parts are subjected to global cleaning. With their surfaces remove rust, accumulated soot and various contaminants. Often cleaning and repair of the nozzles is carried out in a special ultrasonic bath. Further experts inspect the mechanism for damage. This step is performed by means of a plunger pump with a pressure gauge and fitting. The pressure gauge allows you to determine the exact pressure at which the injector injecting the diesel fuel.

The online replacement

It Often happens that the manufacturers of injectors indicate in advance the mileage, through which the mechanism must be replaced. Typically, the resource replacement is 110-150 thousand kilometers. For passenger cars is approximately 3-4 years of operation. During this period the injector is not in need of repair and cleaning (of course, the quality of diesel fuel).
