PERFORMANCE AND EXPERIMENTAL ANALYSIS OF C.I ENGINE FUELLED WITH TALLOW OIL ALONG WITH ANTIOXIDANT ADDITIVE

Abstract

In this research work, performance and emission analysis of a single cylinder direct injection diesel engine with pure diesel and blend of diesel and methyl ester of tallow oil in different proportions of B10, B20 and B30.The B20 blend gives better results compare to other blends and also adding different proportions (300ppm, 600ppm, 1000ppm) of p- phenylenediamine additive to B20 blend. The addition of antioxidant to blend improves fuel combustion which helps to reduce the emissions of engine. p-phenylenediamine showed greater
capability to increase the stability of B20. The test was conducted on single cylinder diesel engine under conditions of constant speed and varying load. Brake thermal efficiency of diesel is 27.3% at 2.31kW BP and 26.3% at 2.88kW BP where as brake thermal efficiency of B20+600ppm additive gives 27% at 2.31kW BP and 26% at 2.88kW BP. The results show that B20 and B20 with antioxidant additive produced higher brake specific fuel consumption compare to diesel. Adding additive to biodiesel blend results decrease of HC, CO,
and NOx emissions compare to diesel. Thus, B20 blend with added antioxidant can be used in diesel engines without any engine modifications.
