Abstract

본 발명은 밸브개폐에 따른 에너지 손실을 최소화할 수 있는 간단한 구조의 자동차 엔진의 흡, 배기 밸브 시스템을 제공하는데 있다.The present invention is to provide an intake and exhaust valve system of a vehicle engine of a simple structure that can minimize the energy loss due to the valve opening and closing.

이를 실현하기 위하여 본 발명은, ECU로부터 출력되는 개폐신호에 의해 구동하는 솔레노이드 밸브와, 밸브스템과 일체로 연결되는 피스톤을 보유하는 실린더를 포함하고 있으며, 상기한 솔레노이드 밸브와 실린더가 유로를 형성하여 솔레노이드 밸브의 작용에 따라 피스톤의 승강운둥으로 흡기통로를 개폐하는 자동차 엔진의 흡, 배기밸브 시스템을 제공한다.In order to achieve this, the present invention includes a solenoid valve driven by an open / close signal output from the ECU, and a cylinder having a piston connected integrally with the valve stem, wherein the solenoid valve and the cylinder form a flow path. Provided is an intake and exhaust valve system of an automobile engine that opens and closes an intake passage by lifting and lowering of a piston according to the action of a solenoid valve.
