Abstract:
1. A fuel injection system for an internal combustion engine, the system comprising: a high-pressure side including at least one high-pressure reservoir in which fuel is stored at injection pressure and at least one injector; communicating with the high-pressure reservoir, for fuel injection to a cylinder of the engine; a low-pressure side which communicates at least indirectly with a fuel tank; a communication between the high-pressure side and the low-pressure side, which communication is controlled as a function of the fuel temperature in the high-pressure side, the communication being at least substantially closed at a high fuel temperature so that the high-pressure side is disconnected from the low-pressure side, and the communication being open at a low fuel temperature; and a valve device controlling the communication of the high-pressure side with the low-pressure side, wherein the valve device is disposed in a component in the high-pressure side, such that an inlet of the valve device is at high pressure.
