- ターボチャージャを備える多気筒エンジンにおいて、
排気行程がオーバラップしない気筒群毎に分割される排気マニホールド、
各排気マニホールドの下流部をターボチャージャのタービン入口へ向けて先細形状に絞る排気エゼクタ、吸気行程がオーバラップしない気筒群毎に分割される吸気マニホールド、前記吸気マニホールドと吸気管のインタークーラ下流の分岐部との間に設定される吸気共鳴管、前記排気マニホールドと前記吸気マニホールドとの間を同一の気筒群同士の関係に接続するEGR通路、前記EGR通路に配置されるEGRバルブ、前記EGR通路のEGRバルブ下流に配置される逆止弁、エンジンの加速時や負荷急増時にEGRバルブを一時的に閉じるように制御する手段、を備え、
前記吸気共鳴管は、下記の条件を満足するように設定されるものにあって、共鳴回転速度Nは、前記ターボチャージャのタービン入口圧よりもコンプレッサ出口圧が高くなる運転領域に設定したことを特徴とする多気筒エンジン。
記
- 前記EGRバルブは、EGR通路の入口側へ可能な限り近づけるように配置したことを特徴とする請求項1に記載の多気筒エンジン。
- 前記EGR通路は、EGRバルブと逆止弁との間に配置されるEGRクーラ、を備えたことを特徴とする請求項1または請求項2に記載の多気筒エンジン。
