Claims (1)
- 흡기 매니폴드에 연료를 분사하는 인젝터와; 점화코일의 1차 전류를 제어하여 점화플러그에 불꽃을 발생시키는 점화부와; 크랭크각을 검출하여 실린더 판별 신호를 출력하는 크랭크각 센서와, 1번 실린더의 상사점을 검출하는 1번 실린더 상사점 센서로부터 실린더 판별 신호와 1번 실린더 신호를 입력받아 연료분사시기와 점화시기를 산출하여 상기 인젝터와 점화부를 작동시키는 엔진제어부로 이루어진 연료분사 및 점화시기 제어장치에 있어서,시동신호가 입력되면, 저장부에 저장되어 있는 마지막으로 점화된 최후 실린더와 최후 실린더 판별 신호가 입력된 후의 경과시간인 제1 소정시간을 읽어오는 초기화 단계와;상기 초기화 단계를 수행한 후, 상기 최후 실린더 다음의 실린더를 최초에 점화될 최초 실린더로 산출하고, 크랭크각 센서로부터 첫번째 실린더 판별 신호가 입력될 때까지의 경과시간인 제2 소정시간을 두 개의 실린더 판별 신호 사이의 시간과 상기 제1 소정시간의 차로 산출하는 최초 실린더 산출 단계와;상기 최초 실린더 설정 단계를 수행한 후, 크랭크각 센서로부터 처음 실린더 판별 신호가 입력되면 모든 인젝터를 작동시켜서 모든 실린더에 연료를 분사하고, 상기 최초 실린더를 점화시키는 동시에 최초 실린더 다음의 실린더부터 순차적으로 연료분사 및 점화가 이루어지도록 하는 연료분사 및 점화단계와;시동정지신호가 입력되면, 최후 실린더와 제1 소정시간을 저장부에 저장하는 엔진상태 저장단계;를 수행하여 이루어지는 것을 특징으로 하는 시동시 연료분사 및 점화시기 제어방법.
