Abstract

자동차용 밸브 개폐 장치에서 오버랩 구간이 자동차의 중, 저, 고속에 동일하게 설정되어 있기 때문에 워밍업시 오버랩 구간이 너무 크게 설정되는 상태가 됨으로써 워밍업 안정성이 저하됨과 아울러 배기 가스에 일산화 탄소등이 기준치 이상으로 포함됨과 아울러 출력이 저하됨을 방지하기 위하여, 실린더 헤드(50)의 상단부에 설치된 2개의 캠 샤프트(51,52)중 흡기 밸브측 캠 샤프트(52)의 동작 각도를 변경시켜 밸브 타이밍을 변경시킬 수 있는 타이밍 가변 수단을 실린더 헤드(50)에 설치하여 구성함으로써 배기 가스의 오염을 감소시키고 출력을 향상시킬 수 있다.In the valve opening and closing device for automobiles, since the overlap section is set to be the same as the middle, low, and high speed of the vehicle, the overlap section is set too large during warm-up, so that the warm-up stability is lowered and carbon monoxide in the exhaust gas exceeds the reference value. In order to prevent the output from being lowered, the timing of the valve may be changed by changing the operation angle of the intake valve side camshaft 52 among the two camshafts 51 and 52 provided at the upper end of the cylinder head 50. By providing the variable timing means to the cylinder head 50, the pollution of exhaust gas can be reduced and an output can be improved.
