Abstract
従来の連続可変バルブリフト機構を備えた内燃機関はスロットルバルブを置換してもポンピングロスの削減効果はなく、アイドリング状態を実現するためには必ず別にカム軸の位相を変える可変バルブタイミング機構を必要とした。 本発明は、連続可変バルブリフト機構を備えたバルブのポートの開口部に多少バルブがリフトしてもガス流を阻止する嵌入部を備えたことにより、総開角可変システムを構成したもので、容積型圧力機関にも用いることが出来る。バルブのオーバーラップを無くすことが可能で、バルブタイミングの変化量を大きくできることと、嵌入部を備えたことによる急速にバルブを閉じることが可能な効果と相乗して、ポンピングロスを削減する。下位概念である連続可変バルブリフト兼可変タイミング機構は、単一の制御軸によりバルブ開口タイミングを上死点に保つ制御ができるので、スロットルバルブを容易に置換することができる。
