Description
請求項3に記載の発明は、前記点火時期算出手段が、前記第1の補間値と前記第2の補間値とを比較していずれか遅角側の前記補間値を前記内燃機関の点火時期とすることを特徴とする、請求項2に記載の2系統燃料噴射式内燃機関である。
(1) ECU35は、ステップS1で読み込んだエンジン回転数と吸入空気量の値、およびステップS3で読み込んだ4枚の点火時期マップに基づき、
の値をそれぞれ基本点火時期として算出する。
(2) (1)で算出した(a)の値と(c)の値を補間演算した値を第1の補間値Ig.T(MBT)とする。補間演算は、(a)の値と(c)の値からステップS2で算出したDIインジェクタ15とPFIインジェクタ16の燃料噴射量の比率に依存した値を算出する。たとえば、燃料噴射量の比率がDIインジェクタ15が60%、PFIインジェクタ16が40%の場合、(a)×0.6+(c)×0.4のような演算により値を算出する。
(3) (1)で算出した(b)の値と(d)の値を補間演算した値を第2の補間値Ig.T(TK)とする。補間演算は、上記(2)と同様に行う。
(4) 第1の補間値Ig.T(MBT)と第2の補間値Ig.T(TK)とを比較し、これらのうちいずれか遅角側の値に、ステップS4で読み込んだ補正量を加えた値を点火時期Ig.Tとして算出する。
