Abstract
【解決手段】内燃機関(エンジン)10のクランク角速度DNEを所定クランク角度(15度)ごとに検出し(ハイパスフィルタ800a)、エンジンの燃焼サイクル(クランク角720度)に同期して各気筒iのトルク生成をモデル化するように設定された周期関数Fcyl#iを検索して得た値Fcyl#iと検出されたクランク角速度との積を算出すると共に、算出された積を所定クランク角度区間にわたって積分して移動平均して相関関数Cr#iを算出し(相間関数算出部800b、基準信号生成部800c)、算出された積分値を判定しきい値と比較して失火の発生を検知する(失火判定部800d)。
【選択図】図6
Description
失火の発生がなく、各気筒のトルク偏差がない条件であるが、この場合は、図17に示す如く、失火気筒なしと検出(判定)することができた。
失火の発生がなく、#3気筒のトルクが他の気筒に比べて20%低い条件であるが、この場合も、図18に示す如く、#3気筒を失火と検出(判定)することなく、全気筒が失火なしと検出(判定)することができた。
#1と#2気筒に比べて#3気筒のトルクが20%低く、#4気筒が失火している条件(単気筒失火)であるが、この場合も、図19に示す如く、#4気筒を失火と判定すると共に、他の気筒を失火なしと検出(判定)することができた。
#1気筒に比べて#3気筒のトルクが20%低く、#2気筒と#4気筒が失火している条件(連続2気筒失火)であるが、この場合も、図20に示す如く、#2気筒と#4気筒を失火と判定する一方、#1気筒と#3気筒を失火なしと検出(判定)することができた。
#1気筒と#2気筒が正常燃焼であり、#3気筒と#4気筒が失火している条件(対向2気筒失火)であるが、この場合も、図21に示す如く、#3気筒と#4気筒を失火と判定すると共に、#1気筒と#2気筒を失火なしと検出(判定)することができた。
