  • Exhaust pipe
    Patent number: 9784167
    Abstract: The exhaust pipe comprises an inlet pipe, an outlet pipe and a bend portion arranged between the inlet pipe and the outlet pipe. The bend portion comprises an inlet bend and an outlet bend, wherein a central bend portion defines an intermediate section of inlet bend and outlet bend and wherein the inlet bend and the outlet bend each cover 50 percent of the total bend angle covered by the bend portion. The central bend portion comprises a diameter, which is smaller than a diameter of the inlet bend and of the outlet bend in a bending plane. In addition a bend radius R of the bend portion varies along the bend portion such that a bend radius of the inlet bend is larger than a bend radius of the outlet bend.

  • Muffler for an exhaust system of an internal combustion engine
    Patent number: 9593607
    Abstract: A muffler for an exhaust system of an internal combustion engine comprises: a casing having an inner space, an inlet pipe for sound to enter the muffler, an outlet pipe for sound to exit the muffler, and a separation wall arranged to extend from the inlet pipe to the outlet pipe and being embodied in a manner such as to define first and second acoustical ducts extending through the casing to allow sound propagating along the first acoustical duct to enter the inner space of the casing and to thereafter exit the inner space of the casing again, and to allow sound propagating along the second acoustical duct to acoustically bypass the inner space of the casing.
