Summary:

The ignition delay under various temperature and pressure conditions considering volumetric change is investigated both by experiments and simulation to give some basic data of ignition delay for a DME DI diesel engine. The combustion process in a DME direct injected diesel engine was also observed to help understanding of the difference between DME combustion and that of a diesel fuel. For DME fuel, it was clear that the luminous flame duration is much shorter than that of diesel fuel. The calculated results of ignition delay for high equivalence( =0.4 in this study) showed good accord qualitatively to those of measured at wide range of temperature and pressure conditions investigated in this work. There exists the negative temperature coefficient region near the temperature of 800K. This study shows basic guideline for optimal injection timing for DME fueled compression ignition engines
