To achieve both low emission and high efficiency in an internal combustion engine, hybrid combustion engine is considered useful by of lean premixed combustion. The aim of this new system engine is both utilizing certain ignition and to shorten combustion period of lean premixed gas by diesel spray which provides multi ignition point. In this study, compression ignition characteristics of propane-air mixture is surveyed, while possibility of simultaneous reduction of both NO_x and Soot is fumbled using this engine. As the way of possibility, diesel spray is formed in each reaction processes: before low temperature reaction, during high temperature reaction, after combustion end of propane-air mixture effect of reaction processes of the mixture on diesel spray combustion is surveyed.
