Numerical analysis for mixture formation of a fuel-direct injection engine

Influences of fuel-spray specification on mixture formation in a direct- injection engine were studied. Fuel-spray, mixture and combustion gas behavior was calculated by numerical simulation. From this study we obtained following results. By using skewed type spray, amount of attached fuel on a piston at stratified charge operating mode is less than the case of non-skewed type spray. This leads to faster flame propagation near a piston surface.
