Abstract: In this experimental study, the engine performance and exhaust emissions of a diesel direct injection engine using mixed palm olein–soybean vegetable oil ethyl ester (POSEE) and methyl ester (POSME) have been examined. The results of experimental studies have shown that the torque and brake power output of an engine, which uses biodiesels, is slightly lower and specific fuel consumption is higher than in an engine using conventional diesel fuel. It has also been observed that there is a decrease in both carbon monoxide and hydrocarbon (HC) emissions, which indicates an advantage of exhaust emissions. Although methyl ester|s CO₂ emissions decreased compared with those of diesel fuel, NO and NO_X emissions were higher with the biodiesels.

Keywords: biodiesel; exhaust emissions; engine performance; diesel engines; POSME; POSEE; biofuels; palm olein; soybean vegetable oil ethyl ester; soybean methyl ester; torque power; brake power; carbon monoxide; hydrocarbon emissions; carbon emissions; vehicle emissions; exhaust emissions.
