Patent ID: 8312862

Claim:
An injection system for an internal combustion engine, comprising: a prefeed pump for feeding fuel from a fuel tank, a high-pressure pump disposed downstream from the prefeed pump, for feeding the fuel into at least two injectors, a fuel distributor disposed downstream from the high-pressure pump, which is designed to distribute the fuel to the injectors, a pressure control or pressure limiting valve disposed downstream from the high-pressure pump, with which the pressure to be produced in the fuel distributor can be adjusted or limited, a pressure sensor for determining a pressure downstream from the high-pressure pump and upstream from the pressure control or pressure limiting valve, wherein the pressure sensor, the pressure control or pressure limiting valve and the fuel distributor are formed in a high-pressure module, and the high-pressure module is formed as a structural unit with the high-pressure pump, and at least one of: (a) a temperature sensor formed in the high-pressure module for determining a temperature of the fuel downstream from the high-pressure pump and upstream from the pressure control or pressure limiting valve, (b) a first hydraulic resistance element disposed downstream from the fuel distributor and upstream from the injectors in the high-pressure module, and (c) a fuel accumulator formed in the high-pressure module is disposed downstream from the pressure control or pressure limiting valve, said fuel accumulator being hydraulically coupled to a leakage drain of the injectors.
