これにより、副排気タービン過給機の起動時における給気マニホールドから副排気タービン過給機のコンプレッサ部への逆流現象を防止することができ、副排気タービン過給機をスムーズに回転(起動)させることができて、副排気タービン過給機のサージングを防止することができる。
これにより、副排気タービン過給機の停止時における給気マニホールドから副排気タービン過給機のコンプレッサ部への逆流現象を防止することができ、副排気タービン過給機をスムーズに回転(停止)させることができて、副排気タービン過給機のサージングを防止することができる。
図1は本実施形態に係る舶用ディーゼル機関の概略構成図、図2および図3は本発明に係る舶用ディーゼル機関の作用効果を説明するためのグラフである。
ディーゼルエンジン本体(以下「エンジン本体」という。)2を構成するクランク軸(図示せず)には、プロペラ軸(図示せず)を介してスクリュープロペラ(図示せず)が直接的または間接的に取り付けられている。また、エンジン本体2には、シリンダライナ(図示せず)、シリンダカバー(図示せず)等からなるシリンダ部5が設けられており、各シリンダ部5内には、クランク軸と連結されたピストン(図示せず)が配置されている。さらに、各シリンダ部5の排気ポート(図示せず)は、排気マニホールド6と接続されており、排気マニホールド6は、第1の排気管L1を介して第1の排気タービン過給機(以下、「過給機A」という。)3のタービン部3aの入口側と接続され、第2の排気管L2を介して第2の排気タービン過給機(以下、「過給機B」という。)4のタービン部4aの入口側と接続されている。一方、各シリンダ部5の給気ポート(図示せず)は、給気マニホールド7と接続されており、給気マニホールド7は、第1の給気管L3を介して過給機A3のコンプレッサ部3bと接続され、第2の給気管L4を介して過給機B4のコンプレッサ部4bと接続されている。
また、ケーシングには、一端部をタービン部3a側に突出させ、他端部をコンプレッサ部3bに突出させた回転軸3cが挿通されている。回転軸3cの一端部は、タービン部3aを構成するタービン・ロータ(図示せず)のタービン・ディスク(図示せず)に取り付けられており、回転軸3cの他端部は、コンプレッサ部3bを構成するコンプレッサ羽根車(図示せず)のハブ(図示せず)に取り付けられている。
また、ケーシングには、一端部をタービン部4a側に突出させ、他端部をコンプレッサ部4bに突出させた回転軸4cが挿通されている。回転軸4cの一端部は、タービン部4aを構成するタービン・ロータ(図示せず)のタービン・ディスク(図示せず)に取り付けられており、回転軸4cの他端部は、コンプレッサ部4bを構成するコンプレッサ羽根車(図示せず)のハブ(図示せず)に取り付けられている。

すなわち、図2に示すように、過給機A3を単独運転させている状態から、過給機B4を起動して、過給機A3と過給機B4とを並列運転させるときには、タービン入口弁10を開放し(全開とし)、予め開放しておいた空気放出弁12を徐々に閉めていく。そして、空気放出弁12を徐々に閉めていくことにより、過給機A3および過給機B4のコンプレッサ出口圧力が徐々に上昇し、過給機A3および過給機B4のコンプレッサ出口圧力が所定の圧力までそれぞれ高められることとなる。
なお、逆止弁11は、過給機B4のコンプレッサ出口圧力が、給気マニホールド7の圧力以上になるか、あるいは給気マニホールド7の圧力と略等しくなると開放(全開)するようになっている。
なお、逆止弁11は、過給機B4のコンプレッサ出口圧力が、給気マニホールド7の圧力よりも低くなるか、あるいは給気マニホールド7の圧力よりも所定の圧力低くなると閉塞(全閉)するようになっている。
これにより、過給機B4の起動時における給気マニホールド7からコンプレッサ部4bへの逆流現象を防止する、あるいは大幅に低減させることができ、過給機B4(の回転軸4c)をスムーズに回転(起動)させることができて、過給機B4のサージングを防止することができる。
これにより、過給機B4の停止時における給気マニホールド7からコンプレッサ部4bへの逆流現象を防止する、あるいは大幅に低減させることができ、過給機B4(の回転軸4c)をスムーズに回転(停止)させることができて、過給機B4のサージングを防止することができる。
