Performance test of CVCRV engine using blends of soyabean and mustard oils with petrol

Since fossil fuels are limited sources of energy, the increasing demand for energy has led to a search for alternative sources of energy that would be economically efficient, socially equitable, and environmentally sound. Variations in the heat release rate with respect to crank angle have been observed and compared using blends of soyabean and mustered oils with petrol at different engine loads in computerized variable compression ratio multi-fuel (CVCRM) engine test rig. It is concluded that the maximum heat release rate angle (429.450) is observed by using the blend of 20-PRM at the engine load of 5 Kg while minimum pressure increase rate (265.830) is observed by using the same blend at the engine load of 2.5 Kg. Similarly maximum mechanical efficiency of 35.8% is obtained by using the blend of 20-PRM at the engine load of 5.0 Kg while minimum mechanical efficiency of 11.8% is obtained by using 20-PRS at the engine load of 2.5 Kg.
