ABSTRACT:
Swirl strength is formed to be 1-3.5, and the fuel mist speed of the fuel to be injected into a combustion chamber is formed to be 5-37 m/s or 5-25 m/s, whereby the air fuel ratio (A/F) is used as the lean limitation. Further, a control apparatus determines a lean combustion region according to the swirl strength and the fuel mist speed. By paying using the injection speed of the fuel, the rich air-fuel mixture and the lean air-fuel mixture are stratified by the combination of the swirl shape (the swirl strength) and the fuel mist speed.
