Increasing the water injectiondelay time and water injection pressure resulted in slightly decrease of the residual wall thicknesses of post-filled region.
提高注水压力与增加注水延迟时间时注水后填充部分的残留壁厚略有减小。

The results show that DME operation has longer injectiondelay, lower maximum cylinder pressure, lower ratio of pressure rise, shorter ignition delay in comparison with diesel operation.
