Experimental investigation of performance and emission characteristics of CI engine fuelled with pine oil and cotton seed oil

Abstract

Increase in energy demand, stringent emission norms and depletion of oil resources has led to find alternative fuels that are compatible with internal combustion engines. This paper presents the study of performance and emission characteristics of CI engine fuelled with pine oil and cotton seed oil blended in the blending ratio 70:30, 50:50 and 30:70 respectively. The experiment was carried out in four stroke single cylinder diesel engine by varying the load from 0% to 80%. The result shows the blend of cotton oil and pine oil used as a fuel has increased the brake thermal efficiency with reduction in exhaust gas temperature and specific fuel consumption. By using different blends, it shows the reduction in emission parameters such as CO, CO2, NOX and smoke and yields satisfactory results.
