摘要： A fuel injection system for internal combustion engines, has a distributor tube and a high-pressure pump that is driven as a function of engine rpm and that serves to generate the fuel pressure and throughput required in the distributor tube in the applicable operating state of the engine. The system also includes a fuel metering unit, which is associated with the high-pressure pump and includes a regulating valve which is actuated electromagnetically. The fuel metering unit is disposed in the high-pressure pump, and the outlet of the regulating valve discharges into the low-pressure region of the high-pressure pump. The above design features make a fuel metering unit possible that is capable of metering the exact quantity of fuel desired in the applicable engine operating state to the high-pressure pump of the CR system.
