Recently, lots of researchers have been attracted to develop various alternative fuels and to use renewable fuels in order to solve the exhaust emission problems. DME (Dimethylether) is synthetic fuel, and can be produced from natural gas, coal and biomass. The emission is clean because it contains little sulfur and aromatic components In this study, the fuel was tested to investigate the applicability as an alternative fuel for diesel. This study was carried out by comparing the exhaust emissions and performance of diesel engine with DME, ULSD (ultra low sulfur diesel), LSD (low sulfur diesel) respectively. In order to measure regulated emissions, CO, $NO_{3}$, HC from vehicle different fuel types were used on chassis dynamometer CVS (constant volume sampler)-75 mode and EPA TO-I1A method was chosen for aldehydes analysis.
