Abstract
The imperfect combustion process will be a problem in the development effort of diesel engine’s
performance. Nonhomogen air–fuel mixing process is one of the factors which cause the imperfect
combustion.By heating up the diesel biodiesel up to a certain temperature before it goes through the
high pressure injection pump will lower its density and viscosity. Therefore, when injected in the
combustion chamber, it will formed smaller droplets of fuel spray which result in a more
homogenious air–fuel mixture. Also by using higher temperature will make the diesel fuel easier to
ignite in order to compensate the limited time which is available in high speed operating conditions.
Diesel engine Dong Feng 1 cylinder direct injection at constant speed was used in this research. The
fuel used are biodiesel with temperature variations in the range from 33oC to 90oC . The best thermal
efficiency for biodiesel fuel is 25.3 % at 70oC with 28 % BSFC. In this condition, the fuel
consumption was decreased 8 % by comparing with that at 33oC.
