Claims (1)
- 吸気弁と排気弁との少なくとも一方の開閉タイミングを可変させる可変バルブタイミング機構と、過給機とを備える内燃機関において、過給機が作動して運転状態が過給領域にあり、かつ可変バルブタイミング機構により排気弁と吸気弁とが同時に開いている場合に実施する内燃機関の点火時期補正制御方法であって、
非過給状態において可変バルブタイミング機構が作動している運転時にシリンダ内に残留する吸入空気量と過給状態における運転時にシリンダ内を通り抜ける新気の通過量との差を演算し、
前記差に非過給状態において可変バルブタイミング機構が作動している運転状態に応じた点火時期補正量を乗じた積に基づいて点火時期補正量を演算し、
演算した点火時期補正量により点火時期を補正する内燃機関の点火時期補正制御方法。
