✦ Synopsis

In a direct injection gasoline engine, in order to achieve good stratified combustion, an extremely advanced control of air-fuel mixture is required. For this purpose, the method of diagnosing the quality of the state of mixture formation in combustion chambers becomes necessary. In this research, the state of air-fuel mixture in the combustion chamber of a TOYOTA D-4 was analyzed in space and time by visualization, A/F multi-point measurement and A/F high response measurement, and thus the effects that injection timing, swirl and fuel pressure exerted on mixture formation were elucidated.
