The HCCI is a promising combustion process for simultaneously obtaining low NOx and PM emissions and high thermal efficiency. With the engine technology currently available, however, the HCCI operating region is limited and compression ignition timing is difficult to control. One side, DME has attracted interest as a potential alternative fuel for compression ignition engines. This fuel has a negative temperature coefficient region in which the ignition delay is not shortened even if the compression-induced temperature rises. DME has characteristics which is producing multi-stage heat release through both low and high temperature combustion. Based on the experimental data, this paper discusses the effect of the methane mixture on combustion in a DME fueled HCCI Engine.
