Abstract
Diesel engines have a wide range of applications in transportation and energy sectors. Diesel fuel is depleting every year and energy demands of the world are increasing drastically due to growth in population. The exhaust emissions of the diesel engine have been declared as harmful emissions and they have negative impact on the health and environment. With this background, researchers are trying to find the alternative fuel of diesel. The aim of this research work is to investigate the performance, combustion and emission characteristics of diesel engine fueled with the different blends of biodiesel with the diesel fuel. Different biodiesel blends B20, B50 and B100 were prepared and tested in the diesel to compare their performance, combustion and exhaust emission characteristics with the that of diesel fuel. Engine brake power and torque for biodiesel blends are found to be almost similar to that of diesel fuel. Fuel consumption and brake specific fuel consumption of biodiesel blends are found to be higher for biodiesel blends as compared to that of diesel fuel. Exhaust temperatures of biodiesel blends are recorded lower values. Regarding exhaust emissions, significant reduced emissions have been found in biodiesel blends as compared to that of diesel fuel. Carbon monoxide, carbon dioxide, unburnt hydrocarbons nitrogen oxides are found to be reduced in biodiesel blends as compared to diesel fuel. Oxygen emissions are found to be higher in biodiesel blends. In combustion analysis, biodiesel blends follow the similar trend of in-cylinder pressure profile but their timing is different to that of diesel fuel. It is concluded that the biodiesel blends are the potential candidates in diesel engine which can serve the purpose of reduced exhaust emissions.
