- 内燃機関の始動後、内燃機関の燃焼室に点火毎にイオン電流を発生させ、イオン電流の検出から消滅までの期間のクランク角又は時間の平均を算出するとともに、算出した前記平均と前記クランク角又は時間の測定値との差の絶対値に基づいて偏差を算出し、
前記クランク角又は時間の平均及び前記偏差が所定の条件を満たすとともに、空燃比フィードバック制御が開始されたことを確認した場合に、点火時期の遅角制御を実施する内燃機関の点火時期制御方法であって、
前記所定の条件が、前記クランク角又は時間の平均が予め設定した下限閾値以上上限閾値以下で、かつ、前記偏差が所定の偏差閾値以下という条件であるとともに、
前記上限閾値を、遅角量が大きくなるにつれ大きくしてあることを特徴とする内燃機関の点火時期制御方法。 - 点火時期の遅角制御の実施開始後、前記クランク角又は時間の平均が満たすべき条件を緩和することを特徴とする請求項1記載の内燃機関の点火時期制御方法。
