Abstract
Each cylinder is provided with an ignition plug, two intake valves, direct fuel injector, and a port fuel injector. When homogeneous combustion is demanded, the direct fuel injector and port fuel injector inject fuel on the same engine cycle. The port fuel injector is installed so that the amount of fuel directed toward outer regions of the intake valves is larger than that of fuel directed toward inner regions of the intake valves, thereby causing only fresh air to flow to regions near the inner regions of the intake valves.
