Utilization of Ethanol and Rice Bran Methyl Ester in a Single Cylinder CI Diesel Engine
نویسنده
چکیده
--This research is aimed to investigate experimentally the performance and exhaust emission characteristics of a direct injection (DI) diesel engine when fuelled with blends of conventional diesel fuel and ethanol, blends of rice bran methyl ester with ethanol, blends of diesel and rice bran methyl ester over the entire range of load on the engine. The experimental results showed that the highest brake thermal efficiency was observed with D80/E13/EA7 in diesel/ethanol/ethyl acetate blends in diesel engines with 3-6 degree retarded start of fuel injection and B20/D80 blend of rice bran methyl ester and diesel can be used without any change in fuel injection parameters, but for higher substitution of diesel with biodiesel i.e. from 20% to 100%, fuel injection pressure must be increased by 50 to 100 bar for better engine performance and emissions.
