Fuel Injector Nozzle DLLA151SM145

With the widespread use of diesel engines in vehicles and construction machinery, diesel engines are the heart of power equipment, and their maintenance is even more important. The performance of fuel injectors directly affects various technical parameters of diesel engines. For longer service life, it is necessary to pay attention to the daily maintenance of the fuel injectors. Long-term use found that the normal service life of the fuel injector is generally more than 2400h, but the actual operation proves that due to the lack of timely maintenance, the service life is far from the design value, generally only a few hundred hours, or even dozens of hours will wear out the card died. The main reason for this situation is that there is no certain professional knowledge, which leads to man-made failures, and most of them are dismantled and disassembled randomly, improper cleaning, and the use of low-quality diesel oil, etc., which cause early wear of the injector parts.

It can be seen that the basic condition for reducing the failure of the injector assembly and prolonging the service life is to use diesel that meets the requirements. Only in this way can the normal operation of the diesel engine be ensured. Once there are carbon deposits in the fuel injector parts, engine temperature is too high, and the fuel injector parts are burned to death, it can be judged that it must be caused by the use of unqualified or inferior diesel oil, because inferior diesel oil has poor lubricating performance and sealing performance. The viscosity and viscosity are far below the technical requirements, which will affect the service life of the wear of the nozzle parts
