Description
Claims (3)
- エンジン油槽(18)を装備してなるエンジン(11)と排気駆動過給機(13)とを備え、前記エンジン(11)で燃料を燃焼させ、当該燃焼で発生した動力によってエンジン(11)の駆動軸(12)を駆動し、前記排気駆動過給機(13)が当該内燃機関における前記エンジン(11)から排出される排気ガス流をタービン内で膨張せしめ、当該膨張の際に得られた動力によって、前記エンジンに供給すべき燃焼空気流を圧縮する圧縮機を駆動するように設定されており、かつ前記排気駆動過給機(13)のタービンロータと圧縮機インペラとで形成された排気駆動過給機ランナが第1液圧機械(15)に連結されていると共に、前記エンジン(11)の前記駆動軸(12)が第2液圧機械(17)に連結されている内燃機関において、
(a) 前記エンジン(11)が、当該エンジン(11)における所定の負荷上限値よりも大きな負荷で運転されている状態にあるときには、前記第1液圧機械(15)の液流出口を、前記エンジン(11)に装備されている前記エンジン油槽(18)を介すことなく直接に前記第2液圧機械(17)の液流入口へと接続すると共に、前記第2液圧機械(17)の液流出口を、前記エンジン(11)に装備されている前記エンジン油槽(18)を介して間接に前記第1液圧機械(15)の液流入口に接続することで、前記排気駆動過給機ランナに連結された前記第1液圧機械(15)を液圧ジェネレータとして機能せしめて、前記排気駆動過給機ランナの機械的動力を液圧動力に転換し、当該液圧動力を前記第2液圧機械(17)へと直接に流体的に伝達し、当該第2液圧機械(17)によって前記液圧動力を機械的動力に転換せしめて、当該機械的動力を前記駆動軸(12)の軸出力に追加し、
(b) 前記エンジン(11)が、当該エンジン(11)における所定の負荷下限値よりも小さな負荷で運転されている状態にあるときには、前記第2液圧機械(17)の液流出口を、前記エンジン(11)に装備されている前記エンジン油槽(18)を介すことなく直接に前記第1液圧機械(15)の液流入口へと接続すると共に、前記第1液圧機械(15)の液流出口を、前記エンジン(11)に装備されている前記エンジン油槽(18)を介して間接に前記第2液圧機械(17)の液流入口に接続することで、前記駆動軸(12)に連結された前記第2液圧機械(17)を液圧ジェネレータとして機能せしめて、前記駆動軸(12)の機械的動力の少なくとも一部分を液圧動力に転換し、当該液圧動力を前記第1液圧機械(15)へと直接に流体的に伝達し、当該第1液圧機械(15)によって前記液圧動力を機械的動力に転換せしめて、当該機械的動力を前記排気駆動過給機(13)の駆動力として用いる
ように設定されており、
かつ、
前記エンジン負荷上限値が、前記エンジン(11)における前記圧縮機に供給される駆動力に余裕が生じる負荷の閾値である、前記エンジン(11)の全負荷の85%であり、前記エンジン負荷下限値が、前記エンジン(11)における前記圧縮機に供給される駆動力に不足が生じる負荷の閾値である、前記エンジン(11)の全負荷の25%である
ことを特徴とする内燃機関。 - 前記第1液圧機械(15)および前記第2液圧機械(17)が、それら自体を各々貫流する液体の容積流量を直接調節可能な可変容積形液圧機械として形成されたものである
ことを特徴とする請求項1記載の内燃機関。 - 前記第1液圧機械(15)および前記第2液圧機械(17)が、定容積形液圧機械として形成され、当該各液圧機械(15、17)には、それぞれ吸込み絞り(25、26)が前置接続(つまり液流入口側に配置)されている
