Claims (11)
- 배기 가스가 유동하는 배기 파이프에 설치되어 상기 배기 가스 중의 탄화수소를 흡착 및 탈리시키는 탄화수소 트랩 촉매;
상기 배기 가스의 유동 경로 중에서 상기 탄화수소 트랩 촉매보다 하류에 상기 배기 파이프에 설치되어 질소산화물을 흡착하고, 가열 장치가 내장된 EHC TWC/NSR 촉매; 및
상기 배기 가스의 유동 경로 중에서 상기 탄화수소 트랩 촉매보다 상류에 상기 배기 파이프에 설치되어, 상기 배기 파이프 내부로 에어를 분사하는 에어 인젝터;
를 포함하되,
엔진의 시동 상태에 따라 상기 에어 인젝터에 에어 분사를 위한 제어 신호를 인가하고, 상기 EHC TWC/NSR 촉매에 전원을 선택적으로 공급하는 ECU가 더 구비되고,
상기 ECU에 의한 상기 에어 인젝터의 제어 신호 인가는, 상기 EHC TWC/NSR 촉매에 전원 공급을 차단한 이후에 이루어지는 것을 특징으로 하는 차량의 배기정화장치.
- 삭제
- 제1항에 있어서,
상기 ECU는 운전자의 운전 의지를 판단하고, 운전 의지가 판단된 경우에, 냉각수 온도를 감지하며, 냉각수 온도가 소정 온도 이하일 경우에 상기 EHC TWC/NSR 촉매에 전원이 공급되게 하는 것을 특징으로 하는 차량의 배기정화장치. - 제3항에 있어서,
상기 소정 온도는 80℃ 이하인 것을 특징으로 하는 차량의 배기정화장치. - 제3항에 있어서,
상기 운전자의 운전 의지 판단은, 브레이크 페달의 조작 여부, 혹은 시동 키 삽입여부, 또는 안전벨트 착용 여부, 혹은 이들의 조합에 의해 이루어지는 것을 특징으로 하는 차량의 배기정화장치. - 제3항에 있어서,
상기 ECU의 전원 공급에 의해 상기 EHC TWC/NSR 촉매가 200℃ 이하까지 온도가 상승되게 제어되는 것을 특징으로 하는 차량의 배기정화장치.
