Diesel Injector Fuel Injector 5365904 Denso Injector for Isuzu, Cummins Isb5.9 Qsb5.9

The use and maintenance of the standard fuel injector The use and maintenance of the standard fuel injector is directly related to the power, fuel consumption and emission of the engine after the fuel injection pump is installed. Therefore, the use and maintenance of the standard fuel injector must comply with the following items. Correctly select the corresponding standard fuel injector and standard fuel pipe according to the fuel injection pump model; ②Standard fuel injectors should be used in groups, so that the wear degree of standard fuel injectors in each group is the same, so as to maintain uniform performance for a long time; ③New standard Before using the fuel injector assembly, clean the anti-rust oil and other dirt with gasoline, and keep the entire fuel injector and high-pressure fuel pipe assembly clean; Keep the bending radius as large as possible, and make the oil pipes of each cylinder consistent in shape, and do not bend at the vertical section close to the tight seat of the oil outlet valve. In this way, local small-radius blocking can be avoided, and the overall appearance of the test equipment can be maintained; ⑤ It is forbidden to use high-pressure sealing bowl gaskets at both ends of the high-pressure oil pipe, because the high-pressure impact force is extremely large, and if the gasket is eccentric, it may cause local erosion. Let the gasket material (such as iron filings) enter the high-pressure oil pipe and standard fuel injector.
