Common faults and solutions for diesel injection systems

The diesel engine oil supply system consists of a diesel tank, an oil pump, a low pressure oil pipe, a diesel filter, a fuel injection pump, a high pressure oil pipe, a fuel injector and a return oil pipe. Diesel fuel is sucked out from the diesel tank by the oil pump, and generates a certain pressure. After filtering the impurities through the diesel filter, it enters the fuel injection pump. The fuel injection pump raises the oil pressure of the low pressure oil, and injects the high pressure oil into the combustion through the high pressure oil pipe and the injector. room. Due to the large oil supply of the oil pump, part of the excess diesel oil flows back to the oil pump or diesel tank from the fuel return pipe, and the other part flows back to the diesel tank through the pressure limiting valve and the return oil pipe
