【実用新案登録請求の範囲】[Scope of utility model registration request] 吸気弁および排気弁とは別にエンジンの圧縮工程上死点
近傍において開成して燃焼室内の圧縮空気を前記排気弁
によって開閉される排気通路を通じて流出させるための
エンジンブレーキ用の常閉弁を備えたエンジンにおいて
、運転条件に応じて排気ガスの一部を前記常閉弁を通じ
て燃焼室内に還流するために、前記常閉弁の開弁時期を
前記排気弁が開成した後に変更するための開弁時期制御
手段を備えた排気ガス還流装置。Separately from the intake valve and the exhaust valve, a normally closed valve for engine braking is provided, which opens near the top dead center of the engine during the compression process and causes compressed air in the combustion chamber to flow out through the exhaust passage opened and closed by the exhaust valve. In an engine, a valve opening timing for changing the opening timing of the normally closed valve after the exhaust valve is opened in order to recirculate a part of exhaust gas into the combustion chamber through the normally closed valve according to operating conditions. Exhaust gas recirculation device with control means.
