Abstract: 본 발명은 배기 매니폴드에서 배출되는 배기가스가 이중의 관으로 모아진 후, 다시 하나의 관으로 합류되도록 하기 위한 연결부의 구조를 개선한 듀얼 배기 파이프의 합류부 구조에 관한 것으로,
제1파이프 및 제2파이프가 소정의 구간동안 나란히 배치되고, 상기 제1파이프 및 제2파이프의 끝단이 어퍼 및 로어 플레이트에 의해서 덮어지며, 상기 어퍼 플레이트와 로어 플레이트의 중간부에는 각각 상부 격벽과 하부 격벽이 합류부의 중앙을 향해 돌출형성된 듀얼 배기 파이프의 구조에 있어서,
상기한 제1파이프와 제2파이프의 후방측 끝단부는 서로 면접되도록 소정 구간에 걸쳐 직선면으로 형성되어지되, 상기 제1파이프와 제2파이프 중 어느 일측의 파이프의 직선면이 다른 일측면의 직선면보다 길게 확대된 연장부가 형성되고,
상기한 연장부의 측면으로는 상기한 어퍼 플레이트와 로어 플레이트의 내측면에 각각 돌출형성된 상부 격벽과 하부 격벽의 전방단이 면접되도록 구성된 것을 특징으로 한다.

Abstract: PURPOSE: Flexible pipe structure for dual exhaust pipes is provided to effectively absorb transmission of exhaust vibration of an engine to an exhaust system, improve the engine output through reduction of exhaust pressure and increase of volumetric efficiency, and improve layout of the exhaust system and durability of a bellows. CONSTITUTION: In dual exhaust pipes, first and second exhaust pipes are connected to exhaust ends of a V-shaped engine and the exhaust pipes are extended to the rear end and are joined. Flexible pipe structure for the dual exhaust pipes comprises a pair of dual flanges(12) having two combining holes(13,14) to connect the first and second exhaust pipes; first and second bellows(15,16) combined between the dual flanges, to independently interconnect the first and second exhaust pipes; and an outer blade combined between the dual flanges. The outer blade covers the outside of the bellows.

Abstract: PURPOSE: A front pipe structure for an exhaust system is provided to prevent degradation of volumetric efficiency of engine caused due to the pressure wave generated during exhaust, while reducing vibrations and noises of exhaust system. CONSTITUTION: An exhaust system comprises an exhaust manifold connected to an exhaust port of an engine; and a front pipe(20) for guiding the exhaust gas generated from the rear end of the exhaust manifold to reach a catalyst purifier. The front pipe includes a plurality of dual pipes(22) communicated to the exhaust manifold; a confluent pipe(24) for combining the plural passages formed by the dual pipes into a single passage; a single pipe(26) having an end connected to the confluent pipe and the other end connected to the catalyst purifier; and a cover member(28) having both sides arranged along the outer surfaces of the dual pipes, confluent pipe and the single pipe in an airtight manner such that an air layer is formed between the cover member and the outer surfaces of the pipes.

Abstract: PURPOSE: A muffler is provided to accomplish an effectiveness of a perforated muffler and a semi-active muffler by allowing the section area of an exhaust pipe to be controlled. CONSTITUTION: A muffler(50) comprises a communication unit consisting of an outer pipe(52) having a space portion(60) for an easy flow of an exhaust gas by expanding a side pipe into which the exhaust gas enters, and a variable unit consisting of an inner pipe(54) arranged in the space portion and an expanded portion(58), the inner piper being provided with a first porous pipe(64) having an end thereof blocked and which forms a first porous portion(62), a second porous pipe(68) having an end thereof blocked and which forms a second porous portion(66) and is connected to the outer pipe side, and a resilient member(70) for connecting the first porous pipe and the second porous pipe. The resilient member expands and contracts in accordance with a change in exhaust gas pressure.
