Abstract

본 발명은 린번 엔진(Lean burn engine)에 주로 적용되는 스월 콘트롤 밸브(SCV : Swirl control valve)제어장치, 특히 냉각수를 이용하여 스월 콘트롤 밸브를 구동시키는 제어장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a swirl control valve (SCV) control device mainly applied to a lean burn engine, particularly a control device for driving a swirl control valve using cooling water.

본 발명은 정온기(1) 후바의 라디에터 상부호스(2)측에는 바이패스 호스(3)를 연결하고, 스월 콘트롤 밸브(4)의 축상에는 냉각수의 압력으로 0-90°범위내에 작동가능한 밸브구동 브레이트(5)가 축설치된 스월 콘트롤밸브 구동부(6)를 설치하며, 상기 바이패스 호스(3)중간과 상기 스월 콘트롤 밸브 구동부(6)의 입구측에는 냉각수 유입호스(7)를 연결하고, 상기 스월 콘트롤 밸브 구동부(6)의 출구축과 워터 펌프(8)의 입구간에는 냉각수 유출호스(9)를 연결하며, 상기 바이패스 호스(3)의 단부와 상기 냉각수 유출호스(9)의 중간에는 바이패스 호스(3)의 단부와 상기 냉각수 유출호스(9)의 중간에는 바이패스 호스(3)와 냉각수 유출호스(9)의 흐름을 상대적으로 조절하는 로터리 솔레노이드 밸브(10)를 설치한 것이다.The present invention connects the bypass hose (3) to the radiator upper hose (2) side of the rear of the thermostat (1), the valve drive plate operable in the range of 0-90 ° by the pressure of the coolant on the shaft of the swirl control valve (4) (5) is provided with a swirl control valve drive unit 6 is installed, connecting the cooling water inlet hose (7) to the inlet side of the bypass hose (3) and the swirl control valve drive unit 6, the swirl control A coolant outlet hose 9 is connected between the outlet shaft of the valve drive unit 6 and the inlet of the water pump 8, and a bypass hose is disposed between the end of the bypass hose 3 and the coolant outlet hose 9. A rotary solenoid valve 10 for controlling the flow of the bypass hose 3 and the cooling water outlet hose 9 is installed at the end of the end portion (3) and between the cooling water outlet hose 9.
