  • Converter V-band clamp anti-rotation and assembly aid
    Patent number: 10837344
    Abstract: An anti-rotation and assembly aid clamp for use in coupling a turbocharger and a catalytic converter. The clamp can include a ring body configured to circumferentially clamp the outlet flange to the inlet flange, a torque application device configured to apply a force about the ring body, and an anti-rotation assembly device configured to be engageable with a first coupling post extending from the turbocharger and a second coupling post extending from the convert to exert a clamping force urging the outlet flange toward the inlet flange.
    Type: Grant

  • Exhaust gas seal
    Patent number: 10167765
    Abstract: A gas seal for a pipe joint in an exhaust system configured to receive an exhaust gas flow from internal combustion (IC) engine includes a seal element. The seal element includes an outer surface and an inner surface arranged concentrically about a first axis. The outer surface is configured to seal against a pipe of the exhaust system. The gas seal also includes a flow-guide element fixed to the seal element at the inner surface of the seal element. The flow-guide element defines an aperture having a shape configured to direct and focus the exhaust gas flow away from the first axis. An exhaust system and a vehicle having such a gas seal are also disclosed.
