There are high expectations for Dimethyl Ether as a new alternative fuel for diesel engine. Compared with the conventional diesel engine, DME fueled CI engine have been reported that it has merits which are almost zero soot emission and high thermal coefficiency. Therfore, the only significant disadvantage of the DME, one of oxygenated fuel, operated engine is that higher NOx exhausted. That is, the rate of the NOx emission is much higher than that of diesel engine. Generally EGR system is used to reduce NOx emission.<br/> In this study, we are going to reduce the higher NOx emission and have tried to study effects of EGR rate on Dl DME engine exhaust emission characteristics.<br/> As a results, we have obtained some facts that EGR rate are much more effective on NOx emission reduction than diesel engines.
