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 solar 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 solar with temperature variations in the range from 30oC to 70oC . The best thermal efficiency for solar fuel is 30 % at 60oC with 28 % BSFC. In this condition, the fuel consumption was decreased 4 % by comparing with that at 30oC. Key Words : The imperfect combustion fuel temperature diesel
