Abstract

본 발명은 엔진의 배기루트 상으로 2차공기를 공급함에 있어서, ECU에서 엔진의 운전상태에 따라 최적의 공급상태를 제어하여 공급함으로서 엔진의 배기가스를 재연소시켜 대기중으로 배출되는 배기가스의 유해물질을 저감시킬 수 있는 자동차의 2차공기공급장치에 관한 것으로, 배기포트(11)가 형성된 실린더헤드(10)와, 상기 실린더헤드(10)에 공기를 공급하는 에어클리너(20)와, 에어클리너(20)에 2차공기를 공급하도록 구동력을 부여하는 2차에어펌프(40)와, 상기 2차에어펌프(40)에서 공기를 공급받아 2차공기를 선택적으로 개폐하는 컨트롤체크밸브(32)와, 컨트롤체크밸브(32)를 선택적으로 구동시키는 솔로네이드(31)와, 솔로에이드(31)에 엔진의 운전상태에 따라 구동신호를 인가하는 ECU(30)로 구성된 것이다.In the present invention, when supplying the secondary air on the exhaust route of the engine, by controlling the optimum supply state in accordance with the operating state of the engine in the ECU by re-burning the exhaust gas of the engine harmful to the exhaust gas discharged to the atmosphere The present invention relates to a secondary air supply apparatus for automobiles capable of reducing substances, comprising: a cylinder head (10) having an exhaust port (11), an air cleaner (20) for supplying air to the cylinder head (10), and air Secondary air pump 40 to impart a driving force to supply the secondary air to the cleaner 20, and a control check valve 32 to selectively open and close the secondary air by receiving air from the secondary air pump 40 ), A solonade 31 for selectively driving the control check valve 32, and an ECU 30 for applying a drive signal to the soloade 31 according to the driving state of the engine.
