The effects of in-cylinder charge motion, fuel spray characteristics and piston crown geometry on WOT output of a direct-injection gasoline engine were investigated. The mixture formation process in the cylinder was analyzed by computer simulation and LIF visualization. The results made clear the technical factors for achieving sufficient fuel-air mixing in a DI gasoline engine with a bowl-in-piston geometry optimized for stratified charge combustion.
