Abstract

본 발명은 가솔린 분사장치의 공기계에 관한 것으로, 특히 스로틀 보디를 흡입되는 공기량을 계량하는 공기계량기의 구성을 간단히 할 수 있도록 스로틀 보디의 내주면에 상하로 설치한 에어포일 가이드 로드와, 상기 에어포일 가이드 로드에 삽입되어 상기 스로틀 보디에 유입된 공기의 흐름에 의해 상하로 동작하는 에어포일과, 상기 에어포일의 저면에 일단이 설치되는 가동핀과, 상기 가동핀의 타단이 상기 스로틀 보디의 외측으로 돌출할 수 있도록 상기 스로틀 보디의 일측에 형성한 홀과, 상기 가동핀의 타단에 연결되어 상기 가동핀의 움직임을 전기적 신호로 변환하는 포텐시오 미터와, 상기 포텐시오 미터의 전기적 신호를 공기량으로 환산하고, 이 공기량에 대응하여 인젝터의 연료 분사량을 제어하는 ECU를 제공하여 준다.The present invention relates to an air system of a gasoline injector, and in particular, an airfoil guide rod installed up and down on an inner circumferential surface of a throttle body to simplify the configuration of an air meter for measuring the amount of air sucked into the throttle body, and the airfoil guide An airfoil inserted into the rod and operated up and down by the flow of air introduced into the throttle body, a movable pin having one end mounted on a bottom surface of the airfoil, and the other end of the movable pin protrudes outward of the throttle body. A hole formed at one side of the throttle body, a potentiometer connected to the other end of the movable pin to convert the movement of the movable pin into an electrical signal, and converts the electrical signal of the potentiometer into an amount of air In addition, it provides an ECU that controls the fuel injection amount of the injector in response to the air amount.

따라서 본 발명은 ECU를 제외하고 종래의 열선식 공기 유량계에 비하여 에어포일과, 에어포일 가이드 로드, 가동핀, 홀등의 기구적인 부분과 상기 에어포일의 움직임을 감지하는 포텐시오 미터로 구성되므로 그 구성이 간단하고, 고가의 종래 열선식 유량계량기를 대체하고 저가의 본 발명의 유량계량기를 스로트 보디에 장착할 경우 자동차 가솔린 분사장치의 공기계량기 시스템의 생산비를 절감할 수가 있다.Therefore, the present invention is composed of an airfoil, a mechanical part such as an airfoil guide rod, a movable pin, a hole, and a potentiometer for detecting the movement of the airfoil, except for ECUs. The production cost of the air meter system of the automobile gasoline injector can be reduced by replacing the simple and expensive conventional hot wire flow meter with the low cost flow meter of the present invention in the throat body.
