An Experimental Investigation of Thermal Behavior of Engine Fueled with Diesel and Bio-Diesel Blends B20N and B80N

In the present experimental research work, used vegetable oil methyl ester (UVOME) is derived through transesterification of used vegetable oil using methanol in the presence of sodium hydroxide (NaOH) catalyst. Experimental investigations have been carried out to examine the combustion characteristics in a direct injection transportation diesel engine running with diesel, biodiesel (UVOME), and its blends with diesel such as B20N and B80N.A careful analysis of the crank angle at which heat release occurs was carried out. The result has shown that biodiesel blends has higher heat release and exhaust gas temperature than diesel.
