The Combustion characteristics of a direct injection C.I. engine fueled with dimethyl ether (DME) were investigated. The in cylinder observation of combustion process was conducted using high speed video camera. The concentration change of principal intermediate combustion products was traced by gas sampling. As the results, DME combustion was found to be non luminous because polycondensation reaction over C2 would not proceed. It was also found that ignition occurred in the down stream of the spray, where DME was perfectly gasified. DME evaporated immediately after injection, and in the evaporating zone low temperature oxidation reaction actively took place.
