Abstract

A great part of flint fuel is Hydrogen and carbon's combination, they should be generated steam and carbon gas when combine with oxygen for perfect combustion in the inside of engine but, the pollutive material are discharged, even though perfect combustion condition especially $NO_x$ and Smoke. they are really harmful for health. In this paper was shown the result of discharging gas' reduction quality. which used combination of corona discharge using the high voltage source of common frequency with EGR. $NO_x$ is increased in entire load erea in proportion to increasing of EGR rate and impression voltage. Smoke is increased slowly under 75[%] in load rate but it is increased rapidly in entire load erea and the reduction rate of Smoke is increased in proportion to increasing of impression voltage.

고연료 중 대부분이 수소와 탄소의 결합물이다. 연료들은 엔진 내부에서 완전 연소되었을 경우는 수분인 증기와 $CO_2$가 발생된다. 그러나 대개 불완전 연소가 일어나 $NO_x$나 Smoke가 발생되어진다. 그리고 이 물질은 인해에 매우 해로운 물질들이다. 본 논문에서는 EGR과 상용주파수를 이용한 플라즈마 장치를 조합하여 배기가스 유해물질 제거 특성을 연구하였다. $NO_x$의 경우에는 전압과 EGR율이 증가할수록 유해물질 제거 특성이 우수하였고, Smoke의 경우에는 EGR 율이 증가하게 되면 Smoke의 발생율이 증가하였으나 전압이 증가하게 되면 발생율이 감소하였다.
