Abstract

Many research works have been conducted to improve a lubrication performance on diesel engines working in severe conditions. In this study the lubricant containing diamond nano-powder is applied on a diesel engine, and the engine performance is analyzed. The concentration of nano-diamond lubricant fabricated by the matrix synthesis dispersion method is varied. The test results with the nano lubricants are compared with the base oil. The result shows the improvement of efficiency with friction reduction and exhaust emissions reduction of CO, smoke and so on.

가혹한 조건에서 작동하는 디젤엔진의 윤활성능을 향상시키기 위하여 많은 연구가 진행되고 있다. 본 연구에서는 특수윤활제로 사용되고 있는 나노다이아몬드를 포함한 윤활제를 디젤엔진에 적용하여 엔진성능에 미치는 영향을 분석하고자 한다. 매트릭스 합성분산법에 의하여 제조된 나노다이아몬드 윤활제를 농도별로 실험하여 기본윤활제와 비교하였다. 실험결과 마찰저감에 의한 효율의 향상과 일산화탄소, 스모크 등의 배기 저감의 효과를 확인하였다.
