Description
Claims (4)
- 内燃機関のノッキング判定装置であって、
前記内燃機関のクランク角を検出するためのクランク角検出手段と、
予め定められたクランク角の間における前記内燃機関の振動の波形を検出するための波形検出手段と、
前記予め定めれたクランク角の間において、ノッキングに起因して発生する振動に、内燃機関に設けられる部品の作動に起因して発生する振動が重畳しない運転状態で測定された基準振動波形を予め記憶するための記憶手段と、
前記検出された波形と前記記憶された波形とを比較した結果に基づいて、前記内燃機関にノッキングが発生したか否かを判定するための判定手段とを含む、内燃機関のノッキング判定装置。 - 前記部品は、前記内燃機関の気筒に対して設けられた吸気バルブおよび排気バルブであって、
前記基準振動波形は、前記予め定められたクランク角の間において、前記吸気バルブおよび前記排気バルブが着座しない運転状態で測定された波形である、請求項1に記載の内燃機関のノッキング判定装置。 - 前記部品は、前記内燃機関に燃料を噴射する燃料噴射装置であって、
前記基準振動波形は、前記予め定められたクランク角の間において、前記燃料噴射装置が作動しない運転状態で測定された波形である、請求項1に記載の内燃機関のノッキング判定装置。 - 前記部品は、前記内燃機関に噴射される燃料の圧力に応じて開状態および閉状態のいずれかの状態に切り換わるバルブであって、
前記基準振動波形は、前記予め定められたクランク角の間において、前記バルブが作動しない運転状態で測定された波形である、請求項1に記載の内燃機関のノッキング判定装置。
