摘要

This research work is proposed to test and evaluate the performance, combustion and emission characteristics of variable compression ratio engine fueled with methyl esters of rubber seed oil as biodiesel. Experiments are carried out on variable compression ratio engine by considering the compression ratio, load, fuel blends, injection pressure and supercharging pressure as variables. The response surface method prediction models for indicated mean effective pressure, brake thermal efficiency, specific fuel consumption, exhaust gas temperature, maximum combustion pressure, heat release rate, ignition delay, carbon monoxide, hydrocarbon and nitrogen oxides emission are developed using the experimental results. D-optimality test is carried out to get optimum engine-operating conditions with improved performance and emission. Test is conducted via the fuel blends of 20, 40, 60 and 80 biodiesel with neat diesel, with an injection pressure of 160 bar at a fixed compression ratio of 20 and at different supercharging conditions at 80 load. The results of the experiment are compared with that of diesel, which confirms that significant improvements in performance and emission characteristics are obtained with the help of supercharging. The combustion characteristics of biodiesel blends comprehend with that of standard diesel.
