Diesel combustion of palm oil methyl ester.
Methyl ester produced from vegetable oils is refered as biodiesel. Because it is derived from plants, biodiesel is a renewable fuel which reduces fossil fuel dependence and prevents increase of the greenhouse effect. In this study, performance of Palm Oil Methyl Ester (PME) as diesel fuel was evaluated and compared to that of petroleum derived Swedish low sulfur diesel (MK1) regarding emissions, fuel consumption and characteristics of combustion. Blends of 5 percent and 20 percent PME with MK1 were also tested. Strategies currently used to control exhaust emissions such as Exhaust Gas Recirculation (EGR) and variable injection timing were applied to evaluate fuel behavior. Better ignition quality of PME led to reduction of NOx and HC emissions. Oxygen content in PME led to reduction of soot an CO emissions. Lower heating value of PME caused increase of specific fuel consumption. The results show that PME is a promising alternative diesel fuel regarding emissions, but its high cold filter plug point (CFPP) limits it to be used blended with other fuels during cold weather conditions.
