Experimental Research With Diethyl Ether on Engine Performance and Emissions in a Spark Ignition Engine

In this study, the influences of the diethyl ether addition into pure gasoline were re-searched experimentally in a single cylinder, four stroke, air-cooled spark ignition engine. Experiments were conducted at wide-open throttle and different engine speeds of 2400, 2800, 3200, 3600 and 4000 rpm. The effects of diethyl ether as an additive on engine torque, specific fuel consumption (SFC), thermal efficiency, CO, CO2 and HC emissions were observed. Test results presented that engine torque and power first increased and then decreased with the addition of diethyl ether. SFC increased by about 4.18%, 7.44%, 11.39% and 14.41% with DEE10, DEE20, DEE30 and DEE40 compared to pure gasoline at 2800 rpm respectively. Remarkable reduction were observed on CO and HC emissions with the addition of diethyl ether into gasoline. CO was reduced by 0.67%, 3.39%, 10.61% and 11.11% with DEE10, DEE20, DEE30 and DEE40 compared to gasoline at 4000 rpm respectively. Similarly, HC decreased by 3.70%, 8.82% and 10.58% with DEE20, DEE30 and DEE40 compared to gasoline at 4000 rpm respectively. It was seen that diethyl ether can be used as an additive without modification in spark ignition engines
