초음파진동을 이용한 디젤기관의 성능향상에 관한 연구
The performance improvement of the diesel engine by the ultrasonic vibrations
초록
This paper describes briefly the effect of ultrasonic vibrations on the performance of four cycle diesel engine. Experiments were carried out to clarify the effect of ultrasonic vibrations on the characteristics of viscosity, structure of diesel oil, fuel consumption rate, brake thermal efficiency, smoke emissions, cylinder pressure of engine. The results are obtained as follows: 1. The ultrasonic vibrations of diesel oil result in the decrease of kinematic viscosity, Brachness Index of diesel oil. 2. The ultrasonic vibrations of diesel oil result in the decrease of fuel consumption rate, the improvement of brake thermal efficiency of engine. 3. The ultrasonic vibrations of diesel oil result in the decrease of smoke emissions of engine.
