The emission from exhaust of motor vehicles is a major source of air pollution. As the chemical composition of palm oil differs from that of diesel fuel, it is expected that the composition and characteristics of the emmisions from the combustion of these two fuels shall differ. Recent monitoring of the emmision from the exhaust had shown that operating the multifuel Elsbett engine with palm oil resulted in an improvement when compared with that when operating on diesel fuel under identical conditions. There were reductions in 29.70 of hydrocarbons, 7.6 of nitrogen oxides, and 47.2 in particles. Similarly there was also significant reduction in the emission of benzene, toulene, ethyl-benzene and xylene when diesel was replaced by palm oil as fuel. There were however slight increases in carbon monoxide (by 2.4), carbon dioxide (by 1.2) and also fuel consumption (by 7.0). In terms of smoke characteristics, there were distinct improvements in the BOSCH smoke number (by 29-61) and opacity (by 45-86) in the range of engine operating speeds from 1845 to 4100 rpm.
