Abstract

This is a thesis about the experiment of comparison characteristic of power and exhaust gas in the same condition between diesel engine that is equipped response power 220HP turbocharger to increase effectiveness of the engine which is recently used in a lot of industry which requires high power. Resulting of the experiment with natural aspiration diesel engine and turbocharger diesel engine, difference in low speed is not significant, but in high speed, effectiveness of turbocharger diesel engine is much higher than the other one. In other hand, in exhaust gas experiment, turbocharger model exhausts more $NO_X$ and $O_2$, but it doesn't significantly affect the result when it comes with decreasing of $CO_2$ and effectiveness of increased power characteristic. As a result, the turbocharger diesel engine is economically effective comparing with the natural aspiration diesel engine.

최근 높은 출력을 요구하는 각종 산업분야에서 사용되고 있는 디젤엔진의 효율을 높이기 위해 대응출력 220HP 과급기를 장착한 디젤엔진과 자연흡기식 디젤엔진을 동일한 조건에서 동력계와 배출가스 분석기를 통해 동력특성 및 배출가스 특성을 실험한 논문이다. 자연흡기식 디젤엔진과 과급기를 장착한 디젤엔진을 실험한 결과, 저속에서의 동력특성의 차이는 적었으나 고속에서의 동력특성은 과급기를 장착한 엔진의 출력과 효율이 증가한다는 결과를 얻을 수 있다. 이와는 반대로 배출가스 특성에서는 과급기를 장착한 모델에서 $NO_X$$O_2$등의 배출가스가 증가되었으나 $CO_2$의 저감과 동력 특성 증가의 효율을 볼 때 배출가스의 증가치는 적다고 할 수 있다. 이와 같은 결과를 토대로 과급기가 장착된 디젤엔진이 자연흡기식 엔진 대비 효율성 면에서 경제성이 높다라고 예측된다.
