  • Patent number: 10760455
    Abstract: A poppet valve has an elongated stem that is configured to extend along a longitudinal axis. The poppet valve further includes a valve body that is disposed laterally with respect to the longitudinal axis and located in a spaced apart relation with an end of the elongated stem. The valve body has a pair of opposing faces disposed co-axial with the longitudinal axis of the elongated stem. The poppet valve also includes at least two arcuately shaped appendages depending downwardly from the end of the elongated stem and extending away from the longitudinal axis of the elongated stem. An end of each appendage is disposed in abutment with an annular region defined on one of the opposing faces of the valve body, a perimeter of the annular region being larger than a perimeter of the elongated stem measured about the longitudinal axis.

  • Publication number: 20140345557
    Abstract: A valve for use in an internal combustion engine is disclosed. The valve includes a stem connected to a fillet disposed between the stem and a seat face. A port receives the stem and accommodates a seat insert that engages the seat face when the valve is in a closed position. The seat insert is fabricated from a non-cobalt-based alloy or an iron-based alloy and the seat face is coated with a cobalt-based alloy or a nickel-based alloy. The coating may be applied using a thermal spray process, such as HVOF.

  • Publication number: 20100146948
    Abstract: An engine exhaust treatment system. The treatment system includes and a reductant injector adapted to deliver a reductant composition into an exhaust stream moving along an exhaust flow path. A selective catalytic reduction device is disposed downstream from the reductant injector. The selective catalytic reduction device is adapted to reduce an amount of NOx in exhaust gases produced by an engine by reaction of the NOx with ammonia. A basic and/or amphoteric oxide contact surface is disposed along the exhaust flow path.
