Abstract

　ＨＣドージングポンプ等の排気管内燃料供給用のポンプを、シリンダ内燃料供給装置に用いられるポンプと兼用することで、装置コストを低減するためのエンジンの燃料供給装置である。シリンダ内燃料供給路のエア抜きを指令する信号が発生すると、兼用ポンプを作動させ、第１の開閉弁を開状態にし、第２の開閉弁を閉状態にして、兼用ポンプから燃料を、エア抜き用燃料供給路を介してシリンダ内燃料供給路に供給する。また、排気管内への燃料供給を指令する信号が発生すると、兼用ポンプを作動させ、第２の開閉弁を開状態にし、第１の開閉弁を閉状態にして、兼用ポンプから燃料を、排気管内燃料供給路を介して、排気管へ供給する。
