Fuel injection system for internal combustion engines |
摘要 |
A fuel injection system for internal combustion engines is proposed which supplies fuel injection valves with fuel from a high-pressure fuel source, under the control of a control unit. The fuel injection valve has an injection valve member, whose opening or closing position is determined by a pressure that acts upon this injection valve member and that is set in a control chamber. To that end, to perform an injection, the pressure in the control chamber must be relieved; which is achieved with a control valve that opens two different outflow cross sections of an outflow conduit of the control chamber in succession. This makes it possible to accomplish an adapted opening of the fuel injection valve member for a preinjection and for a main injection.
