Abstract

본 발명은 고온 재시동시의 제어방법에 관한 것으로, 메탄올의 연료 혼합비를 감지하는 스텝과, 알콜센서와 온도센서를 사용하여 고온 주행여부를 판단하는 스텝과, 고온 주행 모드에서 엔진의 정지시 냉각장치를 구동하고 응축기가 연결된 제 2 라인으로 밸브를 전환시키는 스텝과, 분사노즐 근처의 온도와 설정온도를 비교하여 설정온도의 범위가 될때 까지 반복 처리하는 스텝과, 분사노즐 근처의 온도가 정상상태로 될때 상기 냉각장치를 정지하고, 밸브를 제어하여 제 1 라인에 연결시키는 스텝을 포함한다.The present invention relates to a control method at high temperature restart, comprising the steps of detecting the fuel mixing ratio of methanol, determining whether the high temperature running by using an alcohol sensor and a temperature sensor, and a cooling device when the engine is stopped in the high temperature running mode Driving the valve and switching the valve to the second line connected to the condenser, comparing the temperature near the injection nozzle with the set temperature, and repeating the process until the set temperature is reached, and the temperature near the injection nozzle is in a normal state. And stopping the cooling device, and controlling and connecting the valve to the first line.
