Abstract
Disclosed is a fuel injection system, in particular a common rail system, for fuel delivery in internal combustion engines, in particular diesel engines of commercial vehicles, with a low pressure circuit in which at least one low-pressure feed pump supplies fuel from a fuel tank to a high-pressure pump which supplies the highly pressurized fuel to a central high-pressure fuel reservoir. In order to simplify the ventilation of the low-pressure circuit, a device is provided for intentionally decreasing the pressure in the low-pressure circuit.
