ABSTRACT:
A fuel injection system with an injector for an internal combustion engine has a binary injection nozzle whose pressure chamber can be alternatingly supplied with fuel and a supplemental fluid. A valve device is provided which can control the high-pressure side fuel delivery to the binary injection nozzle and the connection of the pressure chamber to a low-pressure side and to a supply line of the supplemental fluid. The valve device has a reversing valve that is embodied for controlling the impingement of high or low pressure on the pressure chamber and is also embodied for controlling the filling of the pressure chamber with the supplemental fluid. Therefore, the valve device is improved with regard to more rapid and precise switching operations and is also simplified, resulting in greater reliability and reduced maintenance.
