Abstract
Description
Claims (2)
- HEM상태에서, 공기유량 센서(AFS)의 측정값으로부터 모델링된 흡기 매니폴드의 압력값과, 매니폴드압력 센서(MAPS)가 측정한 실제 흡기 매니폴드의 압력값의 차이를 계산하는 단계와;상기 압력값의 차이가 한계값 이상일 경우, OCV의 고장으로 판단하고, 고장난 실린더를 선택하기 위해 양쪽 뱅크의 람다값을 비교하는 단계와;람다값이 린(lean)하게 측정되는 뱅크가 파악되면 엔진을 FEM 상태로 전환하는 단계와;상기 OCV의 고장이 발생되었다고 판단된 뱅크의 모든 실린더를 CDA 제어를 시작하여 이로부터 OCV가 고장난 실린더를 용이하게 파악하는 단계와;이에 대한 고장코드를 저장하고, 엔진 체크등(MIL)을 점등하는 단계로 이루어진 것을 특징으로 하는 자동차의 CDA 엔진용 오일제어밸브의 고장진단 방법.
- 청구항 1에 있어서,상기 CDA 제어는 상기 OCV를 작동하여 실린더에서의 연소 여부를 판단하되, 연료분사 및 점화 상태에서, 미연소되는 실린더를 정상 실린더로, 연소되는 실린더를 OCV가 고장난 실린더로 판단하는 것을 특징으로 하는 자동차의 CDA 엔진용 오일제어밸브의 고장진단 방법.
