Abstract
The invention relates to a fuel injection system for an internal combustion engine, specially a diesel engine, comprising a crankcase and cylinder heads. Said system is provided with injectors to inject fuel into the combustion chambers of the internal combustion engine and a high pressure pump which supplies fuel to a common rail supplying fuel to the injectors via high pressure lines. According to the invention, the common rail is lodged in or on the walls of the crankcase. This arrangement of the common rail track and preferably also that of the fuel injectors and the high pressure lines in the housing of the internal combustion engine optimally protects the fuel injection system from external influence and damages while at the same time hermetically closing it from the outside by forming an internal leakage chamber.
