摘要： A muffler cutter exhibits an excellent heat-insulating capability and an excellent sound-absorbing capability, and can improve the exhaust sound quality. The muffler cutter is fitted to a tailpipe of a vehicular exhaust system, the muffler cutter including: an exhaust pipe, a plurality of through-holes being formed in a side wall of the exhaust pipe; a tubular heat shield plate that is provided around the exhaust pipe coaxially with the exhaust pipe; and a sound-absorbing heat insulator that is provided between the exhaust pipe and the tubular heat shield plate, the sound-absorbing heat insulator being partially provided between the exhaust pipe and the tubular heat shield plate so as to have a curved shape, a closed space having a curved shape being formed between the exhaust pipe and the tubular heat shield plate in an area in which the sound-absorbing heat insulator is not provided, and the distance between the exhaust pipe and the tubular heat shield plate in an area in which the closed space is formed being 1 to 50 mm.

摘要： An exhaust muffler device for an internal combustion engine includes an outer housing (2) which defines a sealed chamber (21) and which is connected to opposite inlet and outlet pipes (5, 6), and an initial expansion subchamber (31) and a pre-outlet subchamber (32) disposed in the sealed chamber (21) . The exhaust gas enters the initial expansion subchamber (31) and mainly flows to a tubular passage (321) in the pre-outlet subchamber (32) to be exhausted through the outlet pipe (6). Portion of the exhaust gas flows into the sealed chamber (21) and re-enters into a rejoining region (321b) of the tubular passage (321) to be entrained in the main stream, thereby attenuating noise of the engine with minimal reduction of engine performance.

摘要： A muffler assembly includes a housing defining at least one internal chamber. The housing is constructed from a composite material made from a thermoplastic resin and a reinforcing element. The reinforcing element is selected from a group of reinforcing materials consisting of glass fibers, aramid fibers, polyamide fibers, carbon fibers, graphite fibers, mineral fibers, ceramic fibers, carbon nanotubes, nano fillers, mineral fillers, ceramic fillers and combinations thereof. A pipe is received in the housing. The pipe includes at least one opening providing acoustic communication between an internal passage in the pipe and the chamber in the housing. An acoustic attenuating material is received in that chamber.

摘要： An exhaust silencer device for an internal combustion engine which includes: an exhaust pipe (10) that forms an exhaust passage from an engine (1), and an exhaust opening; and a muffler (22) attached to the exhaust pipe (10) so as to silence exhaust sound from the engine (1). The piping lengths of the exhaust passages (L2, L3) on two sides of the muffler (22) are substantially equal. At least one of the two exhaust passages (L2, L3) equal in piping length has a hole (41) that makes the resonance frequencies of the two exhaust passages (L2, L3) different from each other.
