Abstract
Description
電動モータの両側から延びる回転軸の一端側に低圧段圧縮機の羽根車を接続し、前記回転軸の他端側に高圧段圧縮機の羽根車を接続し、前記低圧段圧縮機によって圧縮された吸気を前記高圧段圧縮機により再度圧縮する多段電動遠心圧縮機であって、
前記低圧段圧縮機及び前記高圧段圧縮機は、前記低圧段圧縮機の羽根車の回転によって圧縮された吸気の圧力比と、前記高圧段圧縮機の羽根車の回転によって圧縮された吸気の圧力比とが互いに異なる大きさになるように形成されている。
前記低圧段圧縮機の羽根車の径と、前記高圧段圧縮機の羽根車の径は、互いに異なる大きさを有しているように構成される。
前記低圧段圧縮機の羽根車の形状と、前記高圧段圧縮機の羽根車の形状は、互いに異なる形状を有しているように構成される。
前記電動モータの回転数と前記多段電動遠心圧縮機の吐出圧力又は吐出流量との関係を示すマップと、
内燃機関の作動を制御する上位コントローラが前記多段遠心圧縮機に要求する吸気圧力又は吸気流量と前記マップとを照合して前記電動モータの必要回転数を導出する照合手段と
前記照合手段により導出された前記必要回転数になるように前記電動モータの回転数を制御する制御装置とを備えるように構成される。
前記請求項1に記載の多段電動遠心圧縮機の吐出側が他の過給機の吸気側に接続され、
前記多段電動遠心圧縮機の吐出空気を前記ターボ過給機の遠心圧縮機の吸気側に導入するように構成される。
前記他の過給機は、内燃機関の排気ガスにより回転する排気タービンと、前記排気タービンの回転を受けて回転する遠心圧縮機とを備えるターボチャージャとするように構成される。
吸気を3段の圧縮機で圧縮するので、2段の圧縮機で吸気を圧縮する場合と比較して、より高圧の圧力となった吸気を内燃機関に供給することができる。このため、多段電動遠心圧縮機の回転数を下げても、内燃機関に過給される吸気の圧力を所望の圧力とすることができる。よって、多段電動遠心圧縮機の寿命の低下を防止することができる。
