ABSTRACT:
An internal combustion engine operating with fuel injection, the fuel charge of each cylinder of the engine being divided in two or three portions of different amount, injected sequentially starting with a portion of small amount. The portions of the fuel charge are injected through the same injector in the same combustion chamber. The smaller portions of the fuel charge are accumulated in the injector. The accumulation occurs during the injection of the larger portion of the fuel charge. The accumulated fuel is injected in the next cycle by fuel expansion. When the fuel charge is divided in three portions the large portion of the fuel charge is preceded and followed by small portions.
