Abstract

본 발명은 배기매니폴드의 소음방지구조에 관한 것으로, 배기매니폴드(1)를 통해 배기파이프로 배출되는 배기가스의 음파를 변화시키기 위해 상기 배기매니폴드(1)의 각 분기관(1a,1b,1c,1d) 선단에 유출통로(2)가 형성되어 배기가스가 유통될 수 있는 구조로 되어, 엔진의 연소에 따른 배기가스를 2개의 서로 다른 배출통로를 통해 배출게 함으로써, 각각의 통로를 통과하는 폭발음의 음파를 서로 간섭시켜 확실한 소음 감쇠효과를 얻게 되는 것이다.The present invention relates to a noise preventing structure for an exhaust manifold, and is characterized in that each of the branch pipes (1a, 1b) of the exhaust manifold (1) is provided for changing the sound wave of the exhaust gas discharged to the exhaust pipe through the exhaust manifold , 1c, and 1d, so that the exhaust gas is allowed to flow, so that the exhaust gas resulting from the combustion of the engine is discharged through two different discharge passages, whereby the respective passages The sound waves of the explosive sound passing therethrough interfere with each other to obtain a reliable sound attenuation effect.
