Claims (1)
- 디젤 엔진 조립 최종 라인에서 조립 완료된 엔진을 시험용 지그에 장착한 다음 시험용 지그에 설치되어 있는 엔진 제어장치와 접속하고, 상기 엔진 제어장치의 직렬 통신 라인에 자기 진단장치를 접속하는 과정과;이그니션 스위치 접점을 온에 위치시켜 엔진 제어장치에 전원을 공급하여 자기 진단장치와의 연결이 정상적으로 이루어졌는지를 판단하는 과정과;상기 자기 진단장치와 연결이 정상적으로 판단되면 자기 진단장치로부터 압축 시험을 위한 엔진 가속 시험 요구신호가 입력되는지를 판단하는 과정과;엔진 가속 시험 요구신호가 입력되면 구동시작 시간을 대기한 후 모든 인젝터를 오프한 상태에서 스타터 모터를 구동시켜 엔진을 소정 회전 크랭킹시키는 과정과;상기 엔진의 크랭킹 과정에서 각 실린더간의 각속도를 측정하여 자기 진단장치로 전송하는 과정과;엔진 제어수단으로부터 각 실린더간 각속도를 수신한 자기 진단장치는 각 실린더별 각속도가 기설정 한계치 범위를 벗어났는가를 판단하는 과정과;상기 단계에서 각속도가 기설정 한계치 범위를 벗어났으면 해당 실린더의 피스톤 계통 조립에 불량이 발생한 것으로 판단하여 해당 메시지를 출력하는 과정을 포함하는 것을 특징으로 하는 디젤 엔진의 조립 검사방법.
