In the diesel engines, the trade-off relations for reducing both Soot and NO emissions cannot be avoid. In this study, it is proposed that a concept on simultaneous reduction of NO and Soot emissions in Diesel engine exhaust by use of the Diesel fuel oil (n-Tridecane) mixed with liquefied CO_2. The combustion process inside the S.I. engines and diesel engines seems to be affected mixture formation process of the injected or charged fuels. In addition, the spray structure of the liquefied CO_2 mixed fuel is difference from the spray structure of the diesel fuel. Therefore, in this paper, to be clarified the mixture formation process of the liquefied CO_2 mixed fuel, the vapor concentration distribution of n-Tridecane in liquefied CO_2 mixed fuel were observed by exciplex fluorescence method. And vaporization process of CO_2 in liquefied CO_2 mixed fuel were evaluated by measuring spray momentum.
