Claims (3)
- エンジンの吸気弁および排気弁を、開閉時期を可変に駆動するようにしたエンジンの動弁装置において、
上記吸気弁および上記排気弁の開閉時期を各々制御するための制御手段を備え、
その制御手段は、上記エンジンの始動に際し、上記エンジンの燃焼室内の混合気が着火するまでは、排気行程のときに、上記排気弁を閉弁状態に保持すると共に上記吸気弁を開弁して、上記燃焼室内の未燃混合気を吸気系に逆流させ、かつ、上記排気行程のときに吸気系に逆流させた未燃混合気を、次の吸気行程のときに、上記吸気弁を開弁して上記燃焼室内に再吸入させると共に、その吸気行程のときの上記エンジンの燃料噴射量を低減させることを特徴とするエンジンの動弁装置。 - 上記制御手段は、上記燃焼室内の混合気が着火した後、上記吸気弁および上記排気弁の開閉制御を通常制御に移行する請求項1記載のエンジンの動弁装置。
- 上記エンジンはディーゼル機関である請求項1または2記載のエンジンの動弁装置。
