EVALUATING PERFORMANCE AND EMISSIONS OF CI ENGINE RUN BY BLENDS OF MOSAMBI PEEL METHYL ESTER AND DIESEL FUEL

An experimental study is carried out; a mixture of Mosambi peel methyl ester fuels produced from Mosambi peel pyro oil was blended in 10%, 15% and 20 % with Diesel fuel. The Mosambi peel methyl ester and diesel blends were tested in a direct injection mono cylinder natural aspirated diesel engine and its four different loads and 1500 rpm engine speed. It is experiential that the loads with the earlier stage combustion timings as a result of more cetane number of Mosambi peel methyl ester fuel. performance results shows that the thermal efficiency with the Mosambi peel methyl ester addition was decreased meant for the all engine The most heat discharge rate and the in cylinder pressure rise rate were slightly decreased as well as the combustion duration was normally increased with the Mosambi peel methyl ester adding. On the other hand, important altering was not experiential on the maximum in cylinder pressures. In count, it was experimental that the mean effective pressure values be to some extent different depending on the start of combustion timing and the center of heat release position. It is found with the intention of 5 % and 10% Mosambi peel methyl ester fuel adding up resulted in to some extent rise on break specific fuel consumption (increased 5%) as well as decrease on break thermal efficiency (increased 3.5%). Mosambi peel methyl ester added extras also increased NOx emissions cognizant to 9% and decrease smoke with hydrocarbon emissions as well as CO emissions for the entire engine loads. Some reduction was experiential at the full engine load. Also, CO2 emissions were to some extent increased for the each engine loads.
