Description
図1はこの発明の一実施の形態による内燃機関の始動制御装置の主要部の機能構成を示すブロック図である。図2は図1の内燃機関の始動制御装置を含む内燃機関の制御システム全体を示す構成図である。なお、一般的にエンジンには、複数のシリンダ2が設けられているが、図2では、そのうちの1つのシリンダ2について説明する。
なお、図4、図5の始動時燃料噴出量Ptにおいて、始動時の傾斜部分が燃料温度(気化状態)に応じた始動時の適切な噴射量を示し、図5のハッチング部分が再始動時補正係数Prによる燃料噴射量の低減部分を示している。
Pt=Pc(Tw)*Pa(Da)*Pk(Tf、Tw、Da)*Pr(Pt、Tf,Tw)
となる(例えばPc(Tw)はTwに応じて定まるPcを意味し、*は乗算又は加算の所定の演算を示す)。
