Abstract

본 발명은 태핏(TAPPET)을 이용한 자동차 엔진의 흡기밸브 조절기구에 관한 것으로써, 캠과 밸브의 사이에 태핏을 설치하여 엔진의 속도 즉, 엔진이 공회전이나 저속 및 중속과 고속에 따라 상기 태핏의 피스톤이 유압에 의하여 승하강되어지며 밸브의 길이에 변화를 주어 결과적으로 흡기밸브의 개폐시간을 조절함으로써 엔진의 공회전 및 저,중고속시에는 흡기밸브가 보다 일찍 닫혀 흡기효율이 향상되고 고속시에는 흡기밸브가 늦게 닫혀 엔진의 힘(성능)이 향상되도록 한 것이다.The present invention relates to an intake valve control mechanism of an automobile engine using a tappet, and a tappet is installed between a cam and a valve, so that the speed of the engine is changed according to the engine speed, that is, the engine is idle or low speed and medium speed and high speed. The piston is raised and lowered by hydraulic pressure, and the length of the valve is changed. As a result, the opening and closing time of the intake valve is adjusted. As a result, the intake valve is closed earlier at idle, low and medium speed of the engine, and the intake efficiency is improved. The intake valve closes late to improve engine power.
