    　View Summary

    In the research carried out for this paper, an injection strategy for predictably PCCI combustion with Alternative fuel of GTL, a series of experiments using a single-cylinder diesel engine and a spray observation vessel. The Injection system was revised by several injection timing, rate of injection quantities, and second injection ratio to optimize for spray-tospray collision and spatial and temporal distribution of the mixture. The results show that switching injection pattern improve IMEP, and the spray-to-spray collide two-stage injection, reduces NO without increasing CO and THC emissions.
