[概略構成]
図1及び2は、本実施例に係る内燃機関とその燃料系及び吸排気系の概略構成を示す図である。内燃機関1は、軽油及び圧縮天然ガス(以下、CNGと称する)を燃料として使用可能な車両駆動用のエンジンである。内燃機関1は圧縮着火式のエンジンである。内燃機関1は、軽油とCNGとを混合燃焼させることで運転することができ、また、軽油のみを燃焼させることによっても運転することができる。
CNGは、メタンを主成分とするため、着火性が非常に低く燃焼し難い。そのため、内燃機関1において軽油とCNGとを混合燃焼させた場合、CNGの燃焼が不十分となる場合がある。その結果、内燃機関1において軽油のみを燃焼させた場合に比べて、内燃機関1からのHC排出量が増加する虞がある。
本実施例の変形例について説明する。本変形例では、内燃機関1において軽油とCNGとの混合燃焼が行われる燃焼形態として、CNGの消費量が比較的大きい燃焼形態とCNGの消費量が比較的小さい燃焼形態とのいずれかを車両の運転者等が選択することが可能となっている。この場合、ECU20には、内燃機関1の機関負荷Qe及び機関回転速度Neと要求CNG混合割合R_CNGとの関係を示すマップとして、第一CNG混合割合マップと第二CNG混合割合マップとの二つのマップが記憶されている。第一CNG混合割合マップは、CNGの消費量が比較的大きい燃焼形態用のマップであり、第二CNG混合割合マップは、CNGの消費量が比較的小さい燃焼形態用のマップである。
尚、本実施例においては、内燃機関1の燃料を軽油及びCNGとしたが、本発明に係る液体燃料及びガス燃料はこれらに限られるものではない。本発明に係る液体燃料は、圧縮着火することが可能なものであればどのような燃料でもよく、例えば、軽油とGTLとを混合したものであってもよい。また、本発明に係るガス燃料は、メタンを主成分とするものであればどのような燃料でもよく、例えば、プロパンガスやブタンガスであってもよい。内燃機関1の燃料として軽油及びCNG以外の燃料を用いた場合も、圧縮着火する液体燃料を着火元としてガス燃料が燃焼する。
