It has been understood that DME combustion with the low fuel pressure using electronic controlled injector was not stabilized by defective mixture formation, though the excellent thermal efficiency was obtained at appropriate injection timing. In this paper, the improvement of combustion process in DME compression ignition engine with low-pressure fuel injection was investigated with focusing the influence of the fuel pressure and the combustion assistance by homogeneous charge. As a result, it has been understood that the fuel mixture formation and the combustion are promoted due to the active contact between the fuel molecules and the oxygen molecules, because of the reinforcement of the fuel penetration and securing of positive ignition condition.
