Abstract

본 발명은 다기통, 스파크 점화 엔진용 촉매 컨버터용 가열장치를 제공한다.
점화기관의 반수 4기통의 경우 기통 #2와 기통 #3을 공기 과잉율이 0.6의 과농 혼합기체에서 운전하고, 수소, 일산화탄소 및 미연소 성분의 가연개스를 생성시키고, 다른 반수의 기통 #1과 기통 #4는 연료의 공급을 정지하여 공기 블러워로서 이용하도록 하고, 반수의 기통 #2와 기통 #3에서 생성된 가연개스와 다른 반수의 기통 #1과 #4에서 공급된 공기의 혼합에 의한 가연 혼합기체를 배기계의 촉매의 상류에서 설치한 스파크 플러그 등의 점화기구를 내설한 연소기에서 연소시켜 촉매를 급속 가열하도록 한다. 이 장치는 특별한 연료공급장치 및 공기 블로워를 필요로 하지 않고 촉매를 급속 가열 활성화한다.
