  • 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

  • Patent number: 10738655
    Abstract: A turbocharger for an internal combustion engine having a close coupled catalyst assembly includes a turbine housing having a toroidal-shaped low pressure exhaust gas chamber having a plurality of vanes disposed proximate the outer circumferential wall of the low pressure exhaust gas chamber. The vanes are arranged to disrupt the rotational flow of the exhaust gases as they exit the turbine housing to provide a more even flow though the catalyst element of the close coupled catalyst assembly.

  • Patent number: 10683885
    Abstract: A cover member includes a body member made of a composite material and including a mounting flange. A plurality of compression limiters are disposed in the mounting flange, the compression limiters have a predetermined thickness and an internally threaded aperture therein. The dual function compression limiters eliminate the need for separate threaded inserts. With the dual function compression limiter, every bolt location provides a potential location for a jack screw.

  • Patent number: 9897056
    Abstract: A protective cover assembly for a fuel pump in a motor vehicle includes a hooded cover having a first face and a second face in addition to distal and proximate stud bolts, and a base fastener. The hooded cover defines a plurality of apertures operatively configured to receive a corresponding fastener. The distal stud bolt may be operatively configured to affix a distal end of the hooded cover to a cam carrier. The proximate stud bolt may be operatively configured to affix a middle region of the hooded cover to the cam carrier while the base fastener may be operatively configured to affix a lower portion of the hooded cover to the cam carrier. The proximate stud bolt includes an outer diameter feature which is operatively configured to engage with a plunger region of the pump assembly when the proximate cover assembly is subjected to a load.

  • Publication number: 20130091832
    Abstract: A clamp includes a curved band having an inner surface, an outer surface, a first end, and a second end. The band is characterized by a substantially V-shaped cross-section in a radial plane of the band. The inner surface of the band defines the inside contour of the V-shaped cross-section. The clamp also includes a fastener configured to draw together the first and second ends such that the band may be tightened around adjacent flanges of objects to be clamped together. The inner surface is configured to squeeze the flanges together and clamp the objects. The band includes a reinforcement configured to stiffen the substantially V-shaped cross-section and minimize yielding of the cross-section when the objects are being clamped. An engine assembly that includes a first exhaust component and a second exhaust component having respective first and second flanges being squeezed and clamped together via the clamp is also disclosed.
