Abstract

본 발명은 엔진의 연료계통에 있어서, 연료를 분사하는 인젝터가 설치되는 연료분배관에 온도센서를 설치하여 최적의 분사온도가 아닐경우에 보다 많은 연료를 분사하도록 제어 함으로서 연료와 흡입기의 공연비를 기압 및 온도의 변화에 가변적으로 대응하여 공연비를 안정적으로 유지함과 동시에 유해배출가스의 저감을 이룰수있는 자동차의 연료분사제어장치에 관한 것으로, 연료를 저장하는 연료탱크(10)와, 연료탱크(10)의 연료를 공급받아 다수개의 인젝터(100)에 분배공급하는 연료분배관(20)과, 연료분배관(20)에 장착되어 엔진의 연소실에 연료를 분사하는 인젝터(100)와, 잔유된 연료를 써지탱크(40)의 부압에 의해 연료탱크(10)로 재순환시키는 리턴파이프(70)로 구성된 연료분사장치에 있어서, 상기 연료분배관(20)의 내부에 연료의 온도를 감지할 수 있는 서미스터(60)를 설치하여 연료의 온도에 따른 분사량을 ECU(80)에서 조절하도록 한 것이다.The present invention relates to an engine fuel system in which a temperature sensor is provided on a fuel distribution pipe provided with an injector for injecting fuel so as to inject more fuel when the optimum injection temperature is not set so that the air- The present invention relates to a fuel injection control apparatus for an automobile capable of stably maintaining an air-fuel ratio corresponding to a change in temperature and also capable of reducing harmful exhaust gas. The fuel injection control apparatus includes a fuel tank (10) An injector 100 mounted on the fuel distribution pipe 20 for injecting fuel into the combustion chamber of the engine, and an injector for injecting the residual fuel into the combustion chamber of the engine. A fuel injection device comprising a return pipe (70) recirculated to a fuel tank (10) by a negative pressure of a surge tank (40), characterized in that the fuel injection pipe By installing the thermistor 60, which is one of injection quantity according to the temperature of the fuel so as to control in ECU (80).
