摘要： One aspect of the present disclosure provides an exhaust unit including a housing, a wall member, a catalyst, and a muffler chamber. The housing includes a feed inlet and a discharge outlet. The housing is configured such that an exhaust gas of an internal combustion engine is introduced from the feed inlet, and the exhaust gas is discharged from the discharge outlet. The wall member is disposed in the housing, and forms a cylindrical flow path that guides a flow of the exhaust gas introduced from the feed inlet to curve along an outer circumference of an interior of the housing. The catalyst is disposed in the flow path. The muffler chamber communicates with the flow path in a downstream side of the catalyst in the flow path. The wall member serves as a part of a wall that defines an inside and an outside of the muffler chamber.

摘要： To elongate an exhaust tail pipe wherein a muffler is covered by a rear cowl. An exhaust structure of a vehicle including a rear cowl covering a vehicle rear portion, a rear bank-muffler including a first and second expansion chamber partitioned by a partition, a first and second connecting pipe connecting the expansion chambers, and a tail pipe configured to discharge exhaust air from the rear bank-muffler. The rear bank-muffler is covered by the rear cowl, wherein outlines of the rear bank-muffler and the rear cowl are each formed such that the width decreases toward the vehicle rear. The tail pipe, the first connecting pipe, and the second connecting pipe are provided so as to penetrate the partition. A position where the tail pipe penetrates the partition and positions where the first connecting pipe and second connecting pipe penetrate the partition are offset from each other in the vertical direction.

摘要： An apparatus and method for attenuating sound from an engine exhaust. The relative lengths of the expansion chambers and other components within the apparatus provide a quadruple tuning effect which attenuates sound over a wide frequency range. Attenuation at higher frequencies is also increased and extended by the use of acoustically lined internal baffle tubes inside the apparatus housing.

摘要： A first connection pipe, which penetrates a partition wall, and extends to a second expansion chamber side from inside a first expansion chamber, and a second connection pipe, which extends to an exhaust outlet side from the partition wall inside the second expansion chamber are provided; first outer periphery connection holes, which allow exhaust gas from an exhaust pipe to flow out to the second expansion chamber, are formed in the outer peripheral surface of the first connection pipe; second outer periphery connection holes which allow the exhaust gas having flowed out to the second expansion chamber through the first outer periphery connection holes to flow into the second connection pipe, are formed in the outer peripheral surface of the second connection pipe; the first connection pipe and the second connection pipe are arranged such that they are partially parallel to each other; and the first outer periphery connection holes are arranged closer to the exhaust outlet side than the second outer periphery connection holes.

摘要： A muffler (1) for an exhaust system of an internal combustion engine has a housing (2) with an expansion chamber (6). An inlet pipe (7) extends into the housing (2) and has an end section (8) with an outlet opening (9) to the expansion chamber (6). A main outlet pipe (10) has an initial section (11) protruding into the end section (8) of the inlet pipe (7). A secondary outlet pipe (15) has an inlet opening (16) in the expansion chamber (6). A gap (14) in an overlapping area (13) between the end section (8) and the initial section (11) forms a bypass in the end section (8) of the inlet pipe (7), which bypasses the initial section (11) of the main outlet pipe (10). Through the bypass gap (14), exhaust gas flows from the inlet pipe (7) into the expansion chamber (6) and out the secondary outlet pipe (15).

摘要： An exhaust resonator comprises a first cover having an inlet. A first end of a stabilizer tube is connected to the inlet. A second end of the stabilizer tube aims at a primary reflection surface at a first end of an expansion cone surrounding the stabilizer tube to define a first expansion space. A second end of the expansion cone aims at a secondary reflection surface inwardly of a first cover. A first end of an outer case surrounds the expansion cone. A second end of the outer case connects to a second cover that is provided with the outlet. A second expansion space is defined by the expansion cone and the outer case. The second expansion space is terminated by a baffle with an opening on an interface between the outer case and the second cover. The first cover is provided with at least one coolant liquid opening.
