已经理解，尽管在适当的喷射正时获得了优异的热效率，但是使用电子控制喷射器的低燃料压力的DME燃烧并不稳定于有缺陷的混合物形成。本文研究了低压喷油对二甲醚压燃式发动机燃烧过程的改善，重点研究了燃油压力对燃烧过程的影响以及均质进气对燃烧过程的辅助作用。结果，可以理解的是，由于燃料分子和氧分子之间的主动接触，由于燃料渗透的加强和可靠点火条件的保证，促进了燃料混合物的形成和燃烧。
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.
