Abstract
In the study, the effect of the ultrasonic energy in transportational diesel fuel on the engine performance and exhaust emission has been investigated for indirect injection diesel engine. It was tested to estimated change of engine performance and exhaust emission characteristics for the transportational diesel fuels and the reforming fuels which was irradiated by the ultrasonic energy. The results of the study may be concluded as follows; By the irradiation of ultrasonic energy on the diesel fuel, cylinder pressure, heat release rate and engine power were increased but bsfc, mass fraction burned, and smoke were reduced. Also, the combustion was more stabilized and became complete and NOx was increased.
