Experimental Analysis of Performance, Combustion and Injection Characteristics of Biodiesels Obtained From Waste Cooking and Canola Oils

Abstract

This study investigates the injection and combustion parameters of a heavy duty diesel engine fueled with biodiesels such as waste palm oil methyl ester (WPOME) and canola oil methyl ester (COME). In this study, the engine tests were conducted at 1000, 1500 and 2000 rpm of constant engine speeds under the full load condition. The experimental results show that when the heavy duty diesel engine was fueled with WPOME or COME, the engine performance weakened in comparison with the fossil diesel fuel (FDF); on average, the brake power reduced by 4.2% while brake specific fuel consumption (bsfc) increased by 9.2%. But, the net indicated work areas obtained by use of biodiesels were slightly wider than pure FDF. When using biodiesels in the test engine, the start of injection timing take placed earlier than FDF.
