Description
図1に示すように、車両に搭載される内燃機関としてのV型6気筒エンジン300は、複数のシリンダが図面を垂直方向に見てV字状に形成されているシリンダブロック350と、シリンダブロック350の上部にそれぞれ連結される左側シリンダヘッド302と、右側シリンダヘッド304とを備え、左側気筒群306と、右側気筒群308とを形成している。以下、これら気筒群をバンクと称する。本実施の形態において、エンジン300は、V型6気筒の直噴ガソリンエンジンであるとして説明するが、特にこれに限定されるものではなく、複数のバンクを有していれば、水平対向エンジン、または、W型エンジンに本発明を適用してもよい。また、6気筒に限定されるものではなく、4気筒であってもよいし、8気筒であってもよい。さらに、筒内直接噴射型(直噴型)ではなく、ポート噴射型のエンジンに本発明を適用してもよい。
以下、本発明の第2の実施の形態に係る内燃機関について説明する。本実施の形態に係る内燃機関を搭載する車両は、上述の第1の実施の形態に係る内燃機関を搭載する車両の構成と比較して、エンジン300の停止時に、左バンク306の位相角を、右バンク308の最遅位相角と略同じ位相角に制限する中間位相止め機構が設けられる点が異なる。それ以外の構成は、上述の第1の実施の形態に係る内燃機関を搭載する車両の構成と同じ構成である。それらについては同じ参照符号が付してある。それらの機能も同じである。したがって、それらについての詳細な説明はここでは繰り返さない。
