Use of dimethyl ether (DME) as a diesel fuel alternative has been increased due to the unique combustion characteristics of this oxygenated fuel. We have investigated performance and combustion characteristics of a naturally aspirated diesel engine using DME as the main fuel. In the experimental part of this work, OM314 direct-injection diesel engine was used as a base engine. A comprehensive full cycle was coupled with a multizone combustion model to simulate performance characteristics of the engine. Results of the volumetric efficiency showed that the highest brake torque was achievable in midspeed range. The power speed diagram showed that the brake torque tended to be much higher for diesel fuel than for DME when the engine speed was less than 1900 rpm. However, in engine speeds higher than 1900 rpm, brake torque in DME mode of operation was larger. Calculated emission results also suggested that negligible soot is produced in DME mode operation.
