Abstract
엔진의 과열 상태로 엔진 냉각수 온도가 과다 상승하면 공연비를 제어하여 엔진의 냉각수 온도를 제어할 수 있도록 하는 엔진 과열시 공연비 제어 장치 및 그 제어 방법을 제공하기 위하여, 엔진의 냉각수 온도에 해당하는 전기 신호를 출력하는 엔진 냉각 수온 감지 수단과; 상기 엔진 냉각 수온 감지 수단에서 입력되는 신호를 판독하여, 엔진의 냉각수 온도가 설정 온도 이상일 경우에 연료 분사량을 제어하기 위한 공연비의 상태를 농후한 상태로 가변시켜 해당 양의 연료를 분사할 수 있는 제어 신호를 출력하는 엔진 제어 수단과; 상기 엔진 제어 수단에서 인가되는 제어 신호에 따라 동작 상태가 가변되어 해당 실린더로 연료를 분사하는 연료 분사 장치로 이루어져 있다.In order to provide an air-fuel ratio control apparatus and a control method thereof when the engine is overheated so that the engine coolant temperature can be controlled by controlling the air-fuel ratio when the engine coolant temperature is excessively increased due to the overheating of the engine, an electrical signal corresponding to the coolant temperature of the engine Engine cooling water temperature detection means for outputting; A control capable of injecting a corresponding amount of fuel by changing a state of an air-fuel ratio for controlling the fuel injection amount when the engine coolant temperature is higher than a predetermined temperature by reading a signal input from the engine cooling water temperature detecting means. Engine control means for outputting a signal; The operation state is changed according to a control signal applied from the engine control means, and a fuel injection device for injecting fuel into the cylinder.
