Abstract

주행중인 차량의 흡배기 계통에 최적의 재순환 배기 가스량이 제공될 수 있도록 제어하는 장치로서, 엔진의 흡기 계통에 공기 유량계와, 흡기압 센서와, 전공 제어 모듈 밸브와, 배기 가스 재순환 장치를 장착하여, 상기 공기 유량계로부터 검출되는 흡기 매니홀드의 흡입 공기량(Q_a)과, 상기 흡기압 센서로부터 검출되는 흡입 공기압(P_m)과, 엔진 회전수(N_e)와, 각종 부하로부터 전달되는 부하 상태를 제어부가 입력하고, 상기 제어부는 최적의 재순환 배기 가스량을 산출하여 이 값에 따라 진공 모듈 밸브로 전기 신호를 보내면, 상기 진공 모듈 밸브가 전기 신호를 공기 압력으로 변환함으로써 배기 가스 재순환 밸브에 부압을 걸어 배기 가스 재순환 밸브의 개도가 조절되도록 제어하는 가솔린 엔진 차량의 전자 제어 배기 가스 재순환 장치이다.An intake air pressure sensor, a control module valve, and an exhaust gas recirculation device are installed in an intake system of an engine so as to control the amount of recirculated exhaust gas to be supplied to the intake / An intake air pressure P _m detected from the intake air pressure sensor, an engine speed N _e , and a load state transmitted from various loads are calculated as the intake air amount Q _a of the intake manifold detected from the air flow meter, The control unit inputs the optimum recirculated exhaust gas amount, and when an electric signal is sent to the vacuum module valve in accordance with the calculated value, the vacuum module valve puts a negative pressure on the exhaust gas recirculation valve by converting the electric signal into air pressure Controlled exhaust gas recirculation device of a gasoline engine vehicle that controls the opening degree of the exhaust gas recirculation valve.
