ABSTRACT:
A fuel injection system is proposed, having a valve each for the pre-injection quantity and for the main injection quantity, each of the valves having plural injection ports. The injection ports for the pre-injection quantity are smaller than those for the main injection quantity. Furthermore, the injection streams of the pre-injection quantity form a cone angle which is smaller than the cone angle of the main injection streams. By means of the two injection pumps it becomes possible to regulate exactly and indepedently the amount of injection as well as the injection time of the pre-injection quantity and of the main injection quantity.
