Claims (9)
- 内燃機関のエンジンから出る排気ガス流を膨張するためのタービンと、内燃機関のエンジンに供給すべき燃焼空気流を圧縮するための圧縮機とを備え、タービン内で膨張すべき排気ガス流をタービンロータに導入するために、タービンがベンドとして形成された入口室(10)を有し、低いエンジン負荷運転点で入口室(10)に洗浄媒体を供給するために、入口室(10)に洗浄ノズルが付設されている内燃機関の排気駆動過給機において、前記洗浄ノズルが、タービンロータの回転軸線(14)と一致する線上ないし直線上であって、前記タービンロータの延長回転軸線が、前記入口室(10)の壁と交差する位置に配設されており、
前記洗浄ノズルの出口孔の長手軸線はタービンロータの回転軸線と、入口室に注入された洗浄媒体が排気ガス流による方向転換によって入口室のバルブ形デフレクタに衝突し、そのバルブ形デフレクタの領域において霧化されるような角度を成していることを特徴とする内燃機関の排気駆動過給機。 - 入口室(10)に、タービンロータの回転軸線(14)と一致する線上ないし直線上に配置された唯一の洗浄ノズルが付設されていることを特徴とする請求項1記載の排気駆動過給機。
- 洗浄媒体が入口室(10)に流入する洗浄ノズルの出口領域が、入口室(10)の内面(18)に対して垂直に延びていることを特徴とする請求項1又は2に記載の排気駆動過給機。
- 洗浄ノズルの出口孔(21)の長手軸線(19)および洗浄ノズルが配置された延長回転軸線(14)が、20°〜40°の角度を成していることを特徴とする請求項3記載の排気駆動過給機。
- 洗浄ノズルの出口孔(21)の長手軸線(19)および洗浄ノズルが配置された延長回転軸線(14)が、30°〜35°の角度を成していることを特徴とする請求項4記載の排気駆動過給機。
- 洗浄ノズルの出口孔(21)の長手軸線(19)および洗浄ノズルが配置された延長回転軸線(14)が、入口室(10)に注入された洗浄媒体が入口室(10)によって案内される排気ガス流の方向転換によって入口室(10)のバルブ形デフレクタ(12)に衝突するように、角度を成していることを特徴とする請求項3ないし5のいずれか1つに記載の排気駆動過給機。
- 洗浄ノズルが、入口室(10)にねじ止めされたホルダ(16)に収納されていることを特徴とする請求項1ないし6のいずれか1つに記載の排気駆動過給機。
- 洗浄ノズルが、入口室(10)の一体構造部品であるホルダ(16)に収納されていることを特徴とする請求項1ないし6のいずれか1つに記載の排気駆動過給機。
- ホルダ(16)が入口室(10)に一体鋳造され、洗浄ノズルがホルダ(16)に設けられた孔(20、21)によって形成されていることを特徴とする請求項8記載の排気駆動過給機。
