Abstract: 본 발명은 자동차용 머플러에 관한 것으로서,
종래의 머플러는 배기가스에 포함되어 있는 배기소음을 효과적으로 감쇄시키는데에는 문제가없으나 엔진이 고 rpm으로 동작할때 배출되는 높은 압력의 배기가스가 머플러 내부로 유입될때에는 머플러 내부로 공급된 배기가스가 여러경로를 따라 이동되면서 빨리 대기상으로 방출되지 못하게되어 배압이 높아지면서 엔진의 출력 향상에 악영향으로 작용하게되므로서, 엔진이 고 rpm으로 동작할때 엔진의 출력이 감소하게되는 문제점이 발생하였다.
따라서, 상기 문제점을 해결하기 위한 본 발명은 특히 머플러의 내부에서 배기가스의 유동 통로가 되는 유동관의 일측 출구에 배기가스의 압력에 따라 유동관을 차등 개방시키는 밸브를 설치하고, 배출관을 길게 유선형으로 형성시켜 엔진이 저rpm으로 구동할때에는 소음을 효과적으로 감쇄시키고, 엔진이 고rpm으로 구동할때에는 배기압이 낮아지도록 하여 엔진 출력이 향상되도록 한 자동차용 머플러에 관한 것이다.

Abstract: PURPOSE: A dual muffler exhaust device is provided to improve the timbre of a noise by balancing the noises of a left and a right mufflers and to let a user adjust the level of the noise. CONSTITUTION: A dual muffler exhaust device includes a front exhaust pipe(2) and a left and a right main mufflers(3,4). The distances from the intersection of a connecting pipe(7) and the front exhaust pipe to the left and right main mufflers are the same. The timbre of the noise generated at the left muffler is the same as that of the right muffler. If a driver rotates an adjusting handle clockwise, an umbrella-shaped valve plate advances into a chamber. Then, the sectional area of the chamber is reduced and the level of the booming sound decreases. Upon counterclockwise rotating the adjusting handle, the level of the booming sound increases.
