Description
このエンジンシステムは、前述の通りFFVに搭載されたシステムであり、エンジン1には、E25〜E100までの任意の混合比のアルコール含有燃料が供給される。ここで、図2は、ガソリンの気化特性とエタノールの気化特性とを比較する図である。尚、図2は、1気圧下における温度変化に対する、ガソリン及びエタノールそれぞれの蒸留量(%)の変化を示している。ガソリンは多成分燃料であることから、各成分の沸点に応じて蒸発する。ガソリンの蒸留量は、温度変化に対しおおよそ線形的に変化することなる。つまり、ガソリンは、エンジン1の温度状態が比較的低いときにも一部の成分が気化して、可燃混合気を形成することが可能である。
