筒内噴射エンジンにおいて噴霧特性が混合気・燃焼挙動に及ぼす影響の数値解析(熱工学,内燃機関,動力など)

抄録

Influences of fuel spray characteristics on mixture and combustion behavior in a direct injection Gasoline engine were studied. Fuel-Air 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.
