Fuel injection system for internal combustion engine has arrangement for carrying away leaks between pressure side of high pressure fuel pump and low pressure region of fuel injection system

摘要

The fuel injection system has a high pressure fuel pump (17) with at least one pump element (19) and a priming pump (1) that transports fuel from a tank (5) to the suction side of the pump element(s) via a metering unit (37). An arrangement (28) for carrying away leaks is arranged between the pressure side of the high pressure fuel pump and a low pressure region of the fuel injection system.
