A REVIEW PAPER ON PERFORMANCE OF DIFFERENT BLENDS ON CI ENGINE

Compression engines play an important role in daily life. On the other hand it releases the hazardous pollutants which cause the affect on environment. Also the existence of fossil fuel is the question for the future generation. So many researches are conducted to find the alternative fuels for the fossil fuel to enhance the performance & emission characteristics of the engine. As renewable, biodegradable, and nontoxic fuel research has continued into present development of next generational fuels, biodiesel has attracted significant amount of attention over the past decade, Many researches carried out on biodiesel made up from edible and non edible oils. The experiments carried on the diesel engine to analyze and compare the emission and performance characteristics of engine purely running on diesel and by use of biodiesel. In this paper different methodologies are discussed to compare the variable properties of biodiesel. Response surface methodology (RSM) is prefer for the comparison of variable properties. Charge dilution is another way of increasing the engine performance by using biofuels. Over the past years, blending of alcohols (methanol, ethanol and butanol) with diesel fuel has been found to have significant effects on the emissions from diesel engines. Viscosity, volatility, calorific value, cetane nos, flash point is the important properties for of biodiesel fuel, which affects on the engine performance and emission characteristics. However, the biodiesel has a slightly higher viscosity and lower volatility compared to the diesel fuel.
