Abstract
A combustion chamber is formed using a flat piston having a low cooling loss and therein a forward tumble is generated. A fuel spray is formed by a provision of a splitter which is provided to make off-set from a center of an injection port at a tip end of a tumble atomization system fuel injector. The fuel spray is divided into a fuel spray having a strong penetration force and a fuel spray having a small penetration force. The fuel spray having the strong penetration force is injected in a vicinity of an ignition plug. Accordingly, a fuel adhesion to the piston can be reduced and further a reduction of a discharge HC and a fuel consumption can be improved.
