- In many countries, emission values are limited on low-power engines. Catalytic converter and smoke filter are not used in these engines and NOx and smoke emission values are high in this type of engines. In this study, the effects of using the blends of diesel - diethyl ether (DEE) as an alternative fuel on engine performance and emissions was investigated. Test fuel blends were prepared as2.5%, 5%, 7.5% and 10% (by vol.) DEE in defined amount of diesel fuel. In present experiments, brake thermal efficiency (BTE), specific fuel consumption (SFC), exhaust gas temperature (EGT) and gas emissions such as nitrogen oxides (NOx), carbon monoxide (CO), unburned hydrocarbons (HC) and smoke emissions were measured. Experimental results showed that increasing amount of DEE in blends, BTE and SFC increased whereas, NOx, smoke, CO and HC decreased. Also, EGT reduced with rising the rate of DEE. Maximum increase in BTE was achieved 8% with DEE7.5. At the same time, the maximum increase in SFC was achieved with DEE10 at 10%.Furthermore, as long as addition of DEE was proceeded, NOx and smoke emissions become lower. Maximum reduction of NOx emission was obtained by using DEE10 with 56%, nonetheless by the same fuel blend also CO emissions declined about 45%. The smoke and HC were decreased about 31% and 28% respectively with DEE7.5.
