Abstract
본 발명은 차량의 배기가스 후처리장치에 관한 것으로, 더욱 상세하게는 엔진시동 초기의 일정시간동안 촉매 컨버터 전면의 배기 파이프내로 수소와 공기를 분사하여 그 혼합기에 불꽃방전을 시켜줌으로서 배기가스를 일차 산화시켜줌과 동시에 그 발생열로 배기계를 촉매활성화 온도로 조기상승시켜 엔진 시동초기에 배기가스의 정화를 효율적으로 행하도록한 차량의 배기가스 후처리장치에 관한 것이다.The present invention relates to an exhaust gas post-treatment apparatus for a vehicle, and more particularly, to an exhaust gas post-treatment apparatus for a vehicle, in which hydrogen and air are injected into an exhaust pipe on the front face of a catalytic converter for a certain period of time at the start of engine startup, And at the same time, the exhaust system is quickly raised to the catalyst activation temperature by the generated heat, so that the exhaust gas is efficiently purified at the initial stage of engine startup.
