Abstract: 본 발명은 엔진출력 향상을 위한 배기장치에 관한 것으로서,
종래의 배기시스템은 배기관 및 머플러에 고정된 형상을 부가하여 배압을 저감시키고 있으며, 최근에 개발된 가변 머플러의 경우도 밸브개폐를 통해 제한된 2가지 또는 3가지 모드정도밖에 변경되지 않기 때문에 모든 조건의 엔진 회전수에 따라 배기계 및 머플러 시스템이 적절히 대응하지 못해 효과적으로 배압을 조절하지 못하는 문제점이 발생하고 있었다.
따라서, 상기 문제점을 해결하기 위한 본 발명은 배기관의 후단부에 제 1 및 제 2 테일파이프를 형성하고, 배기관의 바닥면에 차량의 주행풍 세기에 따라 상기 제 2 테일파이프를 선택적으로 개방시키는 밸브수단을 형성하므로서, 배기소음 및 배압특성을 적절히 조절하여 엔진출력을 극대화 시킬 수 있도록 한 엔진출력 향상을 위한 배기장치에 관한 것이다.

One end of a pressurizing pipe(25) is received in the front exhaust pipe received in the muffler, while the other end is placed on the bottom surface in front of the muffler. The upper and lower portions of the pressurizing pipe are bent in different directions to induce a portion of the exhaust gas flowing into the muffler to the bottom surface of the muffler. A pivot valve(26) formed on the bottom end portion of the pressurizing pipe is opened by the pressure of the exhaust gas. One end of a discharge pipe(27) is received in the rear exhaust pipe, while the other end is placed on the rear bottom surface of the muffler. The condensate water collecting on the bottom surface behind the muffler is drained to the rear exhaust pipe.
