PERFORMANCE AND EMISSION OF CI ENGINE FUELED BY TURPENTINE AND COTTONSEED OIL BLENDS AT VARIOUS INJECTION PRESSURES

In the current study an experimental investigation was carried out with cottonseed oil ester and mineral turpentine oil blend as an alternative fuel in a diesel engine. This study gives the comparative characteristics of performance and emission for the fuel blends and compared with diesel at various injector opening pressures of 190 bar, 210 bar and 230 bar. The experiment was conducted on 5.2 kW single cylinder Compression Ignition engine. Fuel blends in various ratios has been tested. The Turpentine oil was first blended with 20%, 30%, 40% and 50% of cottonseed oil ester to improve the performance of pure turpentine oil as fuel. It was found that the blend T80 which contains 80 % turpentine and 20 % cottonseed oil ester at 210 Bar gives the optimum brake thermal efficiency among all the blends.
