Abstract: 본 발명은 차량 엔진 배기 장치에 관한 것으로,
종래의 차량 엔진 배기 장치는 1차 밸브의 사용으로 부분적인 소음레벨 저감의 이득을 얻을 수 있게 되지만 특정 영역에서만 그 기능을 발휘되는 문제가 있었던 바,
배기파이프에 제1배기 타공부와 제2배기홀을 형성하는 동시에 배플홀을 갖는 배플판과 제2배기홀을 개폐하는 제2배기홀 개폐플레이트, 이동플레이트 및 배플홀을 개폐하는 배플홀 개폐로드를 설치하여 초기 발진영역에서 배기파이프의 제1배기 타공부를 통해서만 배기가 이루어지도록 하고, 2000~3000 RPM의 정속 구간영역에서 제1배기 타공부와 제2배기홀을 통해서 배기가 이루어지도록 하며, 3000 RPM 이상의 고속영역에서 배플홀까지 모두 개방되도록 하는 것을 특징으로 하는 본 발명에 의하면 제2배기홀이 개방되지 않는 2000 RPM 이하와 제2배기홀이 개방되는 2000~3000 RPM, 제2배기홀과 배플홀이 개방되는 3000 RPM 이상의 상세 대역을 구분하여 각 대역에서의 소음과 배압(엔진 성능) 특성을 제어할 수 있게 되므로 소음과 연비, 출력의 3가지를 모두 만족할 수 있도록 차량을 튜닝할 수 있게 되는 등의 효과를 얻을 수 있게 된다.
