Experimental Investigation on Performance of Four Stroke C.I. Engine with Blends of Diesel and MOME using Response Surface Methodology

There is rapid depletion of diesel resources due to increased demand of diesel in the fields of agriculture, power production and transportation. Use of biodiesel can help reduce the dependability on diesel. In this study, biodiesel is prepared through the process of transesterification of mahua oil. Experiments are conducted on single cylinder internal combustion (IC) engine at different loads, compression ratios and blends of biodiesel. Experimental results viz., brake specific fuel consumption (BSFC), brake thermal efficiency (BTE), volumetric efficiency (VE) and mechanical efficiency (ME) are calculated. Experimental results are analyzed using response surface methodology to identify significant parameters for each response and mathematical models are developed. A multi response optimization technique is used to optimize the parameters for minimum BSFC and maximum BTE, VE and ME. Optimum process parameters are found as 3.0142 KW of load, 19.79 of compression ratio and 20% of blends.
