Abstract
(EN)

PROBLEM TO BE SOLVED: To correctly calculate the advance amount of ignition timing based on knocking resistance performance, in a case where fuel injection is shared with an injector for cylinder injection and an injector for an intake passage.

SOLUTION: An engine ECU executes a program comprising: a step S100 for calculating an injection ratio of the cylinder injection injector; a step S220 for calculating the advance amount by using a first map of the largest advance amount of the ignition timing, used when the injection ratio of the cylinder injection injector is one; a step S230 for calculating the advance amount by using a second map having the smallest advance amount of the ignition timing, used when the ratio is zero; and a step S240 for calculating the advance amount by using a third map whose advance amount of the ignition timing becomes larger as the ratio is larger, used when the ratio is larger than zero and smaller than 1.

【課題】 筒内噴射用インジェクタと吸気通路噴射用インジェクタとで燃料噴射を分担している場合に、耐ノッキング性能に基づいて点火時期の進角量を的確に算出する。
【解決手段】 エンジンECUは、筒内噴射用インジェクタの噴射比率を算出するステップ(S100)と、筒内噴射用インジェクタの噴射比率が1である場合に用いられる点火時期の進角量が最も大きい第1のマップを用いて進角量を計算するステップ(S220)と、比率が0である場合に用いられる点火時期の進角量が最も小さい第2のマップを用いて進角量を計算するステップ(S230)と、比率が0より大きく1より小さい場合に用いられる、比率が大きいほど点火時期の進角量が大きくなる第3のマップを用いて進角量を計算するステップ(S240)とを含む、プログラムを実行する。
