Claims (4)
- 過給機(17)の上流側の吸気通路(12)とクランクケース(19)とをブリーザライン(20)で接続した内燃機関の異常判定装置であって、
前記吸気通路(12)の吸気流量を検出する吸気流量検出手段(16)と、前記ブリーザライン(20)の異常を判定する異常判定手段(30)とを備え、前記異常判定手段(30)は、前記吸気流量の変動波形の回転2次成分から算出した数値を所定時間にわたって積算し、その積算値が所定の閾値未満のときに前記ブリーザライン(20)の異常を判定することを特徴とする内燃機関の異常判定装置。 - 前記数値は、前記吸気流量の変動波形の回転2次成分の絶対値を所定時間にわたって積算したものであることを特徴とする、請求項1に記載の内燃機関の異常判定装置。
- 前記数値は、前記吸気流量の変動波形の回転2次成分の1周期における最大値および最小値の差分を所定時間にわたって積算したものであることを特徴とする、請求項1に記載の内燃機関の異常判定装置。
- 前記回転2次成分は、前記吸気流量の変動波形にクランク角速度に対応する正弦波および余弦波を乗算して積分することで算出されることを特徴とする、請求項1〜請求項3の何れか1項に記載の内燃機関の異常判定装置。
