  • Manifold for a multicylinder internal combustion engine
    Patent number: 8584449
    Abstract: A manifold for a multicylinder internal combustion engine which includes a plurality of outlets (1) comprises upper, lower and central shells (15, 5, 51) that are connected with one another and define inlet channels and outlet spaces (63, 65). A baffle plate (35) is attached to different shells (5, 15) by means of a fixed/movable bearing and can expand thermally without transferring thermal stresses to the shells (5, 15).
    Type: Grant

  • Air-Gap Insulated Motor Vehicle Exhaust Duct
    Publication number: 20080203725
    Abstract: An air-gap insulated vehicle exhaust duct has an outer pipe and an inner pipe, between which an air gap is formed. One of the two pipes has a flange fitted thereto, a seal being arranged between the flange and the other pipe, the seal largely sealing the air gap against the outside and, in addition, allowing relative axial and radial movement between the flange and the other pipe when thermal expansion occurs while driving.

  • Exhaust gas system and method of directing a flow of exhaust gas of a vehicular internal combustion engine
    Patent number: 7171800
    Abstract: An exhaust gas system of a vehicular internal combustion engine comprises a plurality of exhaust gas catalytic converters having different working temperature ranges. Depending on the temperature of the exhaust gas the latter is directed to the one or those converters into whose working temperature range the exhaust gas temperature falls.
