Abstract:

The resource depletion has always been a concern regarding petroleum. Due to the increase in the price of petroleum, environmental concern and availability of fuels are greatly affecting the trends of fuels for transportation vehicles. To fulfill the rising energy demand renewable fuel like biodiesel is in
forefront of other technologies. Biodiesel oil one of the options as alternative transport fuel. Cottonseed oil is non-edible vegetable oil, high viscosity, low volatility and widely available in India. In the present study, experimental investigations were carried out on a variable compression ratio diesel engine with
cottonseed biodiesel -diesel blends (10–25% by volume) as fuel to determine the optimum blending ratio for the engine performance and comparative
study done for optimal performance parameters of VCR engine at different compression ratio. It has been observed that B20 blend (20% cottonseed +80%
diesel fuel) gives highest brake thermal efficiency & lowest brake specific fuel consumption as compared to all other blending combinations at different
compression ratios.
