Madyira et al.,[5]. In This paper, Daniel M. Madyira reports on analysis and study of using sunflower oil as an diesel blends for the production of biodiesel as alternatives to diesel fuel. Biofuels are now recognized as an alternative viable option. Some of the difficulties of using biodiesel in conventional diesel engines are their higher viscosity, acidity levels that influences the structural integrity of the engine and low density which results in low calorific value and leading to incomplete combustion. In this process, in the presence of Sodium hydroxide catalyst and methanol batch transesterfication is applied to sunflower oil for the production of biodiesel. The biodiesel was characterized and then conducted using Nuclear Magnetic Resonance (NMR), bomb calorimetry, sulphur content tests and Gas Chromatography (GC) and acidity and flash point …show more content…
Srithar et al.,[7]. In this paper, Srithar proposes that Biodiesel produced from vegetable oils has considered as a promising alternate fuel and also says that the performance study and analysis of two biodiesels from mustard oil and pongamia pinnata oil and they are blended at various mixing ratios with diesel. The result of performance of the dual biodiesel in engine and exhaust emissions were studied in a single cylinder, air cooled, direct injection and high speed diesel engine at different engine loads with a constant engine speed of 3000 rpm. The emissions of smoke opacity, nitrogen oxides and hydro carbon of dual biodiesel blends were higher when compared to that of diesel. But the exhaust gas temperature when compared to that of diesel was lower with dual biodiesel. From the experimental study results, the thermal efficiency and mechanical efficiency of Blends A were slightly higher than the diesel. Blend B and Blend C are very closer when compared to the diesel values. The Brake Specific Fuel Consumption values of dual biodiesel blends were in accordance to that diesel. Some blends produced slightly lower CO and CO2 when compared to that of diesel. Thus it produces a considerable advantage of diesel while using the dual biodiesel
