Abstract
Description
図9において、エンジン52には、給気マニホールド56を介して給気通路58が接続されるとともに、排気マニホールド54を介して排気通路60が接続されている。
給気通路58には、ターボチャージャ70のコンプレッサ70aが設けられている。コンプレッサ70aは後述するタービン70bに同軸駆動されるものである。給気通路58のコンプレッサ20aよりも下流側には、給気通路58を流れる吸入空気と大気で熱交換を行うインタークーラー62が設けられている。また、給気通路58のインタークーラー62よりも下流側には、給気通路58内を流通する吸入空気の流量を調節するスロットバルブ64が設けられている。
図11及び図12において、ウエストゲートバルブ104は、一端を回転軸146に支持され該回転軸146の軸心r’周りに、支持アーム148を介して矢印Wのように回動自在に支持された弁体144と、弁体144が着座する弁座142とを備えている。ウエストゲートバルブ104は、弁体144が弁座142に着座することで閉弁する構成である。
図11及び図12において、弁座142は、バイパス通路の軸方向と垂直な面上に構成されている。
しかし近年、ウエストゲートバルブを積極的にターボチャージャの制御に用いることが求められており、ウエストゲートバルブの開度を全開及び全閉だけでなく中間開度で使用し、タービンのバイパス通路を通過する排気ガス量を調整することが求められている。
従って、バルブ開度によってバイパス流路を通過する排気ガス量を制御することがバルブ開度の小さな領域を含めて全般に容易となる。
これにより、前記弁体を排気ガスの流れと垂直な方向の回転中心をもって回動させることが容易になる。
前記傾斜角が80°を超えると閉弁したときのシール性の確保が難しくなり、閉弁時においてもウエストゲートバルブを排気ガスが通過してしまう可能性がある。
また、傾斜角が45°を下回ると、排気ガス流量を安定して制御することができる効果が小さい。
前記傾斜角が70°以下であると閉弁したときに高いシール性を確保することができる。また、前記傾斜角が60°以上であると、ウエストゲートバルブを通過する排気ガス流量をより安定して制御することができる。
図1及び図2を用いて本実施例のウエストゲートバルブについて説明する。
これにより、弁体44を開く際には、回転軸46を回動させることで、該回転により支持アーム48を介して弁体44が弁座42から離隔する矢印Wのように回動して開弁する。
また、ウエストゲートバルブには組み立てのためのがたつきが存在している場合であって、前記がたつきによってバルブ開度が少量変化しても、ウエストゲートバルブを通過する流量がバルブ開度に鈍感であるので、ウエストゲートバルブを通過する排気ガス流量は大きく変化せず特に問題は生じない。
角度βが図1、図3、図4に示したように、0°<β<90°の範囲であれば、ウエストゲートバルブのストロークの分解能が細かくなり、ウエストゲートバルブを通過する排気ガス流量がバルブ開度に対して鈍感になる効果を得ることができる。
角度αが0°、即ちバイパス通路の軸方向と垂直な面上に弁座が設けられており、角度βが図5~図7に示したように、0°<β<90°の範囲である場合にも、ウエストゲートバルブのストロークの分解能が細かくなり、ウエストゲートバルブを通過する排気ガス流量がバルブ開度に対して鈍感になる効果を得ることができる。
図8から、傾斜角度αが大きいほどウエストゲートバルブを通過する排気ガス流量がバルブ開度に対して鈍感になっていることが確認できる。従って傾斜角度αを大きくするほど、バルブ開度を調整してウエストゲートバルブを通過する排気ガス流量を安定して制御することができるといえる。
傾斜角度αが45°を下回ると、排気ガス流量を安定して制御することができる効果が小さいことから傾斜角度αの下限値は45°とする必要があり、より安定して排気ガス流量を制御するために傾斜角度αの下限値を60°とすることが好ましい。
