Abstract
The invention relates to a fuel injection system for an internal combustion engine. The inventive fuel injection system comprises a high-pressure pump ( ) for delivering the fuel from a fuel reservoir ( ) and a number of fuel injectors ( ) for injecting the fuel into the combustion chamber of the internal combustion engine. The system is further provided with a high-pressure fuel line ( ) that links the high-pressure pump ( ) with the fuel injectors ( ) and that contains a high-pressure reservoir ( ). A fuel return line ( ) returns the fuel that was not injected by the fuel injectors ( ) and a leakage line ( ) returns the leakage amounts that occur at the fuel injectors ( ). According to the invention the high-pressure fuel line ( ), the fuel return line ( ) and the leakage line ( ) are combined in a common fuel line ( ) which is characterized by cross-sections of flow that are separated from one another by walls and that correspond to the individual lines ( ).
