In this laboratory until now, we proposed an epoch-making combustion method using liquefaction CO_2 mixed fuel as the first step of the fuel design concept. This analyzed physical and chemical effects such as the extension of the two-phase region and internal EGR, and it showed a possibility of the simultaneous reduction of soot and NOx. Then, as the second step, a new fuel design concept for engine systems was proposed. This is possibility of low exhaust emission, combustion control, and positively promotes atomization and vaporizing of the spray by using mixed fuel of high boiling and low boiling point. In the experiments, the mixed was injected into a RCEM, and the phenomena was taken by the laser-induced fluorescence method. Analytical results show that the low boiling point fuel distributed the upstream region of the spray, and the high boiling point fuel reached the downstream region of the spray.
