자동차 배기장치의 소음기{The structure of exhaust silencer}[0001] The present invention relates to a muffler for an automobile exhaust system,

본 발명은 자동차 배기장치의 소음기에 관한 것으로서, 더욱 상세하게는 "Y"형으로 분기된 제1,2배기파이프들이 케이싱부재의 양측에 접속되는 구성의 소음기가 장착되어 저속운행을 할 때는 제1분기관을 통해 케이싱부재 내부로 배기가스를 배출하고 저속운행에 의해 낮아진 배기압력을 보정하여 토크(torque)를 안정시키며, 고속운행을 할 때는 제2분기관의 밸브를 열어 제1분기관과 동시에 배기가스를 배출시켜 배기압력을 보정하고, 토크와 엔진의 출력을 상승시켜 배기효율을 높여줄 수 있도록 한 발명에 관한 것이다.
The present invention relates to a muffler of an automobile exhaust system, and more particularly, to a muffler having a structure in which first and second exhaust pipes branched into a Y-shape are connected to both sides of a casing member, The exhaust gas is discharged to the inside of the casing member through the branch pipe and the torque is stabilized by correcting the exhaust pressure lowered by the low-speed operation. When the high-speed operation is performed, the valve of the second branch is opened The exhaust gas is discharged to correct the exhaust pressure, and the torque and the output of the engine are increased to improve the exhaust efficiency.

일반적으로 자동차의 배기장치(exhaust system)는 내연기관에서 배출되는 배기가스를 종합하는 배기 매니폴드(exhaust manifold), 배기 파이프(exhaust pipe) 및 배기 소음을 저하시키는 소음기(exhaust silencer) 등으로 구성되어 있다.2.

상기 배기장치들은 배기 파이프의 중간쯤에 설치되는 서브머플러와 배기 파이프의 말미에 설치되어 내연기관으로부터 배출되는 배기가스의 온도와 압력을 낮추고 소음을 저하시키는 메인머플러로 구분된다.The exhaust devices are divided into a sub-muffler installed at the middle of the exhaust pipe and a main muffler installed at the end of the exhaust pipe to lower the temperature and pressure of the exhaust gas discharged from the internal combustion engine and lower the noise.

종래에는 배기 파이프와 서브머플러를 통해 배출되는 배기가스가 바이패스 되는 구조이므로 엔진의 토크(torque)가 저하되어 엔진의 출력을 높여줄 수 없었으므로 서브머플러를 통해 배출되는 배가가스의 흐름을 지연시켜 엔진의 출력으로 높여줄 수 있는 배기장치의 제안이 절실히 요구되었다.Conventionally, since the exhaust gas discharged through the exhaust pipe and the sub muffler is bypassed, the torque of the engine is lowered and the output of the engine can not be increased. Therefore, the exhaust discharged through the sub muffler delays the flow of the gas A proposal of an exhaust device capable of raising the output of the engine has been urgently required.

On the other hand, when the low-speed operation is performed, the irregular exhaust gas pressure Not only the torque can be stabilized but also the exhaust gas is simultaneously discharged through the first and second branch pipes 21 and 22 while opening the valve 30 of the second branch pipe 22 So that the exhaust pressure can be corrected while the output of the torque and the engine can be increased to improve the exhaust efficiency, so that the torque of the entire vehicle can be increased and the output of the engine can be increased.

이상에서는 본 발명의 바람직한 실시예에 대하여 도시하고 또한 설명하였으나, 본 발명은 상기한 실시예에 한정되지 아니하며, 청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 본 발명이 속하는 분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변형 실시가 가능한 것은 물론이고, 그와 같은 변경은 기재된 청구범위 내에 있게 된다.
While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but many variations and modifications may be made without departing from the scope of the invention. It will be understood by those skilled in the art that various changes may be made and equivalents may be resorted to without departing from the scope of the appended claims.
