In order to provide both higher efficiency and lower pollutant emissions, combustion processes of premixed lean mixture which arise from multi-point ignition will be most promising and required. For this purpose, a compression ignition engine with the inlet port injection of gasoline and the compression ratio of about 18 was manufactured experimentally. In the engine, spontaneous ignition takes place at unspecified points and then the flame develops rapidly throughout the combustion chamber. Within the limits of stable combustion, the engine achieves high efficiency comparable to DI diesel engines, and much lower NOx emission than diesel engines simultaneously.
