EXPERIMENTAL STUDY AND THERMAL ANALYSIS OF A COMBUSTION CHAMBER OF A DIESEL ENGINE FUELLED WITH BLEND OF DIESEL AND KUSUM OIL

MECHANICAL ENGINEERING

The depleting reserves of petroleum and environmental issues have led to the search for more environmental-friendly and renewable fuels. Biodiesel obtained from various renewable sources has been recognized as one of the alternative fuel due to its biodegradability, high cetane no, no sulphur emissions and low volatility. Biodiesel derived from nonedible feed stocks such as kusum oil are reported to be feasible choices for developing countries including India where consumption and cost of edible oil is very high .The aim of present work is to optimize the biodiesel production from kusum oil through tranesterification process. The optimum conditions for maximum yield were obtained at molar ratio of 5:1, reaction time 60 minutes, and at 0.5% catalyst concentration. The various performance and emission parameters like brake power (BP), brake specific fuel consumption(BSFC), brake thermal efficiency (BTE), CO emissions, CO2 emissions, HC emissions, NOx emissions were evaluated at different loads and compression ratios in a 4 stroke, single cylinder CI engine. These performance and emission parameters of diesel fuel were compared with that of B25, B50, B75 and B100. The performance parameters of B25 blend were similar to those of diesel. It was found that CO2, HC and CO emissions decreases as the blend content increases whereas the NOx emissions increases as the blend content increases. Also simulation of combustion chamber of CI engine is done.
