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

This study investigates the injection and combustion parameters of a heavy duty diesel engine fueled with biodiesels such as waste palm oil methyl ester insert ignore into journalissuearticles values(WPOME); and canola oil methyl ester insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(FDF);; on average, the brake power reduced by 4.2% while brake specific fuel consumption insert ignore into journalissuearticles values( 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.
