Description
エンジン10が始動されると、通常は徐々にエンジン冷却水温が上昇する。すなわち、図4のA点に対応するエンジン冷却水温TH(1)から、B点に対応するエンジン冷却水温TH(2)に上昇する。この場合において、DI比率が計算され(S100)、DI比率rが変化していない時(たとえばr=0.7)には、DI比率rが0より大きく1より小さいと判断され(S110にて0<r<1.0)、関数f(3)を用いて、f(3)(THW,r)により冷間進角量が算出される(S140)。
エンジン10が始動されても、車両の周囲の状態(特に温度状態)によっては、エンジン冷却水温が変化しない場合もある。このような場合であって、エンジン10の運転状態が変化してDI比率rが0.7から低下すると、すなわち、図4のA点に対応するエンジン冷却水温TH(1)のままで、r=0.7よりもDI比率rが小さいC点に状態が変化する(この逆でも構わない)。この場合において、DI比率が計算され(S100)、DI比率rが変化していても(たとえばr=0.7からr=0.5)、DI比率rが0より大きく1より小さいと判断され(S110にて0<r<1.0)、関数f(3)を用いて、f(3)(THW,r)により冷間進角量が算出される(S140)。
エンジン10が始動されて、エンジン冷却水温もDI比率rも変化する場合もある。このような場合には、図4のA点に対応するエンジン冷却水温TH(1)かつDI比率r=0.7の状態から、エンジン冷却水温TH(1)よりも高いTH(2)かつDI比率r=0.7よりもDI比率rが小さいD点に状態が変化する。この場合において、DI比率が計算され(S100)、DI比率rが変化していても(たとえばr=0.7からr=0.5)、DI比率rが0より大きく1より小さいと判断され(S110にて0<r<1.0)、関数f(3)を用いて、f(3)(THW,r)により冷間進角量が算出される(S140)。
以下、エンジン10の温度が低い冷間時には限定されない検討例について説明する。本検討例においては、筒内噴射用インジェクタ110の分担比率がDI比率rが、r=0、r=1、0<r<1の3つの場合に分けて、基本点火時期が、エンジンECU300のROM320やRAM340に予め記憶されている。
以下、本実施の形態に係る制御装置が適用されるに適したエンジン(その1)について説明する。
以下、本実施の形態に係る制御装置が適用されるに適したエンジン(その2)について説明する。なお、以下のエンジン(その2)の説明において、エンジン(その1)と同じ説明については、ここでは繰り返さない。
