Particulate matter and oxides of nitrogen are the main pollutants in the tail pipe emissions of bio-diesel fueled engine. In this investigation Mahua methyl ester along with diethyl ether (DEE) used as fuel for the single cylinder DI-Diesel engine, analysis of performance and emission is presented. This paper presents an investigation into the effect of biodiesel blending on performance and emission characteristics of diesel engine. The effect of fuel additive was to control the emission from diesel engine and to improve its performance. But still the research work is going on the bio-diesels application is to make it environmental friendly. In this experiment DEE mixed with the MME at different proportion such as 3%, 5%, 10% and 15% tested at different loads on diesel engine. The addition of diethyl ether to the blends reduced the NOX emission at low and medium loads; however, at high loads the NOX emission was higher compared to diesel and lower compared to the corresponding biodiesel blend. The results obtained from the engine tests have shown a significant reduction in NOx emissions especially for DEE addition of more than 10% on a volume basis and a little decrease in smoke of DEE blends compared with neat MME. Smoke levels are decreased substantially with 15% DEE blend with MME at full load. The thermal efficiency rise and SFC are better in the case of 15% additive blend.


Keywords: Oxygenated fuels, Diethyl ether, Mahua methyl ester, physicochemical properties, viscosity, and specific gravity.
