Hydrogen has been applied for premixed charge or direct injection with forced ignition engines. However they have a lot of problems (knocking, pre-ignition, back fire, after fire) derived from characteristics of autoignition. It is thought that hydrogen diesel engine for an inert gas recirculating co-generation system, proposed by WE-NET project, has potential of becoming a high efficiency and zero emission Internal Combustion Engine (ICE). This ICE still need to have a few things which are optimization of working gas composition, compression ratio and injection conditions so that more reliable autoignition of hydrogen and the stable operation of this ICE can be achieved with minimizing heat loss. In this research, thereby, the influence of temperature, pressure, working-gas composition, equivalence ratio on autoignition delay time were clarified by means of chemical kinetic reaction calculation and experiments of premixed charge compression ignition. And also the effects of concentration of hydrogen and inert gas on autoignition were obtained separately.
