• A direct injection gasoline engine employing a new stratified combustion system has been developed. The combustion strategy was achieved by a fan-shaped fuel spray and a shell-shaped piston cavity (Fig. 1). The process of stratified mixture formation and consequent stratified combustion are strongly affected by the fuel spray characteristics (Fig. 2, 3, 4, 5), therefore numerical analysis (CFD) was applied to understand the phenomena of mixture formation process. From the results of CFD (Fig. 6, 7), it was clarified that the vaporization characteristic is important in making a suitable stratified mixture formation, in addition to the spray liquid characteristics, and CFD enables prediction and analysis of actual phenomena.
