디젤자동차의 저공해 , 고출력용 초음파 연료공급장치의 적용화 개발

This is an experimental study on the chassis dynamometer and high way road testing during a severe winter and summer season. Results obtained to compare with the ultrasonic fuel feeding system and conventional fuel system in diesel automobile engine. The results were as followers in case of the ultrasonic fuel feeding system. 1. In chassis dynamometer testing during given vehicle speeds, output were increased from 4.6 to 11.43 % . brake specific fuel consumption were increased from 6 to 19%, smoke were decreased from 16.7 to 50%. 2. The running fuel consumption ratio in high way road test were decreased by 15.3 % at a severe summer and 20.2 % at a severe winter.
