Diesel engine performance analysis with blend fuel of biodiesel and Turpentine oil as biofuel additive

Experiments were conducted on diesel engine to study and measure the suitability of biodiesel (BD) and Turpentine (T) blend as a replacement for diesel fuel. The result shows that the performance of engine with various blends was found to be near to diesel. Emissions were improved and combustion characteristics were found to be comparable with diesel fuel. The maximum brake thermal efficiency obtained with BD70T30 blend fuel, which is 3.72% lower than that of diesel at full load, but the BSFC increases for blend fuels at part load and also same at full load. Carbon monoxide, Hydrocarbons and Smoke emissions were reduced by 75%, 65% and 62.3% respectively compared to diesel at full load, whereas nitric oxides were increased by 9.08% for BD70T30 blend fuel. Turpentine additive in Biodiesel offer decrease in viscosity and flash point that leads to complete combustion which increases power output. The performance and combustion features with reduced emissions are comparable to diesel and the blend fuel is capable of replacing C I engines diesel fuel.
