From the point of view of global warming and emissions regulations for ships engines, marine gas engine has been developed for using natural gas instead of liquid diesel fuel. The purpose of this study is to reveal the effect of ignition of liquid fuel injection condition to methane gas combustion in injected high-compressed gas directly into the combustion chamber. The experiment results show that the late injection timing of the liquid fuel cause a steep rate of heat release and reduction of injection amount has a small effect to the methane combustion.

从全球变暖和船舶发动机排放法规的角度出发，开发了以天然气代替液态柴油的船用燃气发动机。本研究的目的是揭示液体燃料喷射条件的点火对直接向燃烧室喷射高压缩气体时甲烷气体燃烧的影响。实验结果表明，液体燃料喷射时间较晚导致甲烷的热释放速率较大，而减少喷射量对甲烷燃烧的影响较小。
