Vegetable oils are liquid fuels from renewable sources; they do not over-burden the environment with emissions. Vegetable oils have potential for making marginal land productive by their property of nitrogen fixation in the soil. Their production requires lesser energy input in production. They have higher energy content than other energy crops like alcohol. Vegetable oils can be successfully used in CI engine, through engine modifications and fuel modifications because vegetable oil in its raw form cannot be used in engines. Specific fuel consumption (SFC) have been computed for various 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 out of the two mustard oil blends, 20-PRM shows the lowest specific fuel consumption at the engine loads of 2.5 Kg and 5.0 Kg, where as 15-PRM shows the lowest specific fuel consumption (SCF) at the engine loads of 7.5 Kg. The experiments also show that the lowest specific fuel consumption occurs at the engine load of 7.5 Kg with using the blend of 15-PRM out of all the engine loads considered in the study.
