Abstract (en)

[origin: EP0900932A1] The fuel injection system includes a dual fuel injection nozzle (12), with a pressure chamber (11) where fuel and an addition fluid are alternating supplied. A valve arrangement, has a controllable high-pressure fuel supply to the dual fuel injection nozzle. The connection of the pressure room with a low-pressure side and with an inlet conductor (26) of the additional fluid are also controllable. The valve arrangement includes a switching valve (16) which is formed, both for the control of the supply of the pressure chamber with high or low pressure, as well as for the control of the filling of the pressure chamber with the additional fluid.
