Abstract
본 발명은 질소산화물(N0x)저감용 자동차의 배기장치에 관한 것으로, 배기장치(1)을 구성하는 제2촉매 컨버터(5)의 전단부에 배기가스를 가열시키도록 배터리에 연결된 히터를 갖춘 예열기(7)가 구비되어져, 온도가 저하된 배기가스가 제2촉매컨버터(5)로 유입되기전 질소산화물(N0x) 활성화 온도인 약300도에서 400도 범위로 다시 가열되므로 탄화수소(HC)와 일산화 탄소(CO)는 물론 질소산화물(N0x)의 제거율을 더욱 높여 주도록 된 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an exhaust device for a vehicle for reducing nitrogen oxides (N0x), and includes a preheater having a heater connected to a battery to heat exhaust gas at the front end portion of the second catalytic converter 5 constituting the exhaust device 1. (7) is provided so that the exhaust gas whose temperature is lowered is heated again in the range of about 300 degrees to 400 degrees which is the nitrogen oxide (N0x) activation temperature before flowing into the second catalytic converter 5, and thus hydrocarbon and HC are monoxide. Carbon (CO) as well as to further increase the removal rate of nitrogen oxides (N0x).
