통상적으로 전자 제어 가솔린 분사 장치는 엔진의 출력 증대, 유해 배기가스의 배출 감소, 연료 소비율 절감, 신속한 응답성 등을 동시에 만족시키기 위해 각종 감지기를 부착하고, 이 감지기에서 보내 온 신호를 받아서 엔진의 운전 상태에 따라 연료의 분사량을 전자제어유닛으로 제어하여 인젝터를 통하여 흡기 다기관에 가솔린을 분사시키는 방식이다.In general, an electronically controlled gasoline injector is equipped with various sensors to simultaneously satisfy an increase in engine output, a reduction in emission of harmful exhaust gas, a reduction in fuel consumption, and quick response, and the engine is operated by receiving signals from the detector. According to the state, the injection amount of fuel is controlled by the electronic control unit to inject gasoline into the intake manifold through the injector.

그러나, 종래 구조의 연료 분사량 보정 장치는 도 1 도시와 같이 핫 필름 에어 플로러(Hot Film Air Flow) 측정부가 공기 밀도를 측정함과 동시에 바로 실제의 분사량을 제어하게 됨으로써, 정확한 분사량이 제어되지 못하여 엔진 성능이 저하되는 문제가 존재하였다.However, in the fuel injection amount correction device of the conventional structure, as shown in FIG. 1, the hot film air flow measurement unit measures the air density and simultaneously controls the actual injection amount, so that the accurate injection amount cannot be controlled. There was a problem of degrading performance.
본 고안은 상기 설명한 연료 분사량 보정 장치에 내재되었던 문제점을 해결하기 위해 이루어진 것으로, 본 고안의 목적은 핫 필름 에어 플로어가 공기의 밀도를 측정함과 동시에 이에 적합한 연료량을 산출하여 최적의 상태로 연료가 분사되도록 하는 대기압에 따른 자동차 연료의 분사량 보정 장치를 제공함에 있다.The present invention has been made to solve the problems inherent in the fuel injection amount correction device described above, an object of the present invention is to measure the density of the air while at the same time calculate the amount of fuel suitable for the fuel film in the optimum state The present invention provides an apparatus for correcting an injection amount of automobile fuel according to atmospheric pressure to be injected.
