Performance Evaluation of Some Biodiesel blends in an Insulated Engine

Abstract

Growing concern regarding energy resources and the environment has increased a lot of inquisitiveness in the study of alternative sources of energy, so to meet those energy requirements there has been some strenuous work going on globally in alternative fuels like biodiesels, alcohols and CNG, LNG, LPG and Hydrogen etc. The reason behind the outgrowing interest in Biodiesels is, they can offer a very promising future rather than Diesel oil. Biodiesel blends (20% Biodiesel + 80% Diesel) have given optimum performance in an conventional diesel engine. But engine will encounter problems like low volatility and high viscosity. However, it can be overcome by using these biodiesel in a hot combustion chamber. Because at higher temperature it has the ability to handle low calorific value fuels effectively. This paper reviews and compares various biodiesel blends in an insulated environment of a diesel engine. Before that a suitable insulated environment was selected from three different insulated levels by the earlier researchers is used.
