Hot Sale Common Rail Diesel Fuel Injector 0445120101 in Stock

The common rail injection fuel supply system is composed of high-pressure oil pump, common oil supply pipe, injector, electronic control unit (ECU) and some pipeline pressure sensors. Each injector in the system is connected with the common oil supply pipe through its own high-pressure oil pipe, and the common oil supply pipe plays a role of hydraulic pressure storage for the injector. During operation, the high-pressure oil pump delivers the fuel to the common oil supply pipe with high pressure. The high-pressure oil pump, pressure sensor and ECU work in a closed-loop manner, which can accurately control the oil pressure in the common oil supply pipe, and completely change the phenomenon that the fuel supply pressure changes with the engine speed.
