Claims (2)
- 吸気弁のリフト・作動角を連続的に拡大、縮小させることができるリフト作動角可変機構を備えるエンジンの可変動弁制御装置であって、
エンジンが完爆したか否かを判定する完爆判定手段と、
エンジン始動から完爆後所定時間が経過するまでの間は、前記吸気弁のリフト・作動角を大リフト・大作動角に設定する大リフト・大作動角設定手段と、
エンジン始動から完爆後所定時間が経過した後に、前記吸気弁のリフト・作動角を小リフト・小作動角に設定する小リフト・小作動角設定手段と、
前記吸気弁のリフト・作動角を小リフト・小作動角に設定した後に、点火時期を完爆判定前の点火時期よりも遅角させる点火時期遅角手段と、
を備えることを特徴とするエンジンの可変動弁制御装置。 - エンジンの運転状態に応じて燃料を噴射する燃料噴射手段を備え、
前記燃料噴射手段は、前記吸気弁のリフト・作動角を小リフト・小作動角に設定したときは、大リフト・大作動角に設定したときよりも噴射燃料を少なくする、
ことを特徴とする請求項1に記載のエンジンの可変動弁制御装置。
