Abstract
An experimental study was conducted to evaluate the performance, emission and combustion characteristics of Variable Compression Ratio (VCR) diesel engine with mahua oil methyl ester (MOME) as blended fuel with diesel. A four stroke, single cylinder, water cooled and compression ratio of 17:1, 17.5:1 and 18:1 was used for the experiment. Also the blend ratios are M10, M20 and M30 biodiesel blend was used for conducting the performance, emissions and combustion tests at varying load conditions with a constant speed 1500rpm. Various parameters such as brake thermal efficiency(BTE), brake specific fuel consumption(BSFC), exhaust gas temperature(EGT) and emissions of carbon monoxide (CO), hydrocarbon (HC), smoke and oxides of nitrogen gases (NOx) in exhaust and combustion parameters such as cylinder pressure, heat release rate (HRR), cumulative heat release rate (CHRR) is evaluated. The test results indicates that M10 blend with CR 18:1 shows better performance and lower emissions, but considering the engine vibration and noise of the CR is limited to a value of 18:1.
