High Quality Diesel Fuel Injector Nozzle Dlla155s738 for Peugeot

In order to ensure that diesel oil does not freeze at the lowest temperature, diesel oil with a freezing point about 5 degrees lower than the lowest temperature should be selected during daily maintenance, so as to ensure the service life. To this end, the following points should be done in actual work:
(1) Sedimentation and filtration of diesel oil. The fuel injection pump and fuel injector of the diesel engine are very precise components. The matching gap between the plunger couple and the fuel injector couple is only 0.001mm, and a slight mechanical impurity will cause serious wear and tear. Therefore, diesel oil should be fully precipitated and filtered before use to remove impurities, generally not less than 24 hours.
(2) Regularly clean the diesel filter and diesel tank. Under normal circumstances, the diesel filter should be cleaned every 90 hours and the fuel tank every 450 hours. When cleaning the diesel filter, if the filter element and sealing ring are found to be damaged, they should be replaced in time. At the same time, the oil sludge and water at the bottom of the fuel tank should be completely removed when cleaning the fuel tank. Otherwise, the fuel supply system will be blocked, resulting in insufficient fuel supply, and also Accelerated wear of fuel injection pump and fuel injection nozzle due to unclean diesel.
(3) Diesel oil should be sealed and stored. Doing a good job of sealing and protecting the diesel oil can greatly prolong the life of the fuel injection nozzle assembly, because if it is not sealed during storage, various impurities will take advantage of it, and the diesel oil will be oxidized and gelled due to the influence of external environmental factors. Once it enters the diesel engine The fuel supply system will inevitably affect the life of the fuel injection pump and fuel injector assembly.
(4) Do not use mixed oil. In order to ensure that the life of the fuel injector is not reduced, do not add engine oil, gasoline, alcohol, etc. to the diesel oil during use.
