ABSTRACT: The imperfect
combustion process will be a problem in the development effort of diesel
engine’s performance. Non homogen 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.
