<p>For each cylinder of the internal combustion engine, the fuel injection system has one fuel pump, one fuel injection valve, and one line connecting the fuel injection valve to the fuel pump. To control the injection, a first electrically triggerable control valve is disposed on the fuel pump, by which valve a communication of the high-pressure side of the fuel pump with a relief chamber is controlled. The onset of fuel injection is determined by the closing time of the first control valve, by which the high-pressure side is disconnected from the relief chamber. Near the fuel injection valve, a second electrically triggerable control valve is disposed, by which a communication of the fuel volume, located in the fuel injection valve, with a relief chamber is controlled. The end of the fuel injection is determined by the opening time of the second control valve, and as a result rapid relief of the fuel volume located in the fuel injection valve and thus rapid closure of the fuel injection valve are achieved.</p> |
