  • Patent number: 11162394
    Abstract: A hydraulic lash adjuster for use in diesel engines including a cylinder head having a first valve, a second valve, and a valve bridge extending between and in contact with both the first valve and the second valve. Where the diesel engine includes a first rocker arm, and where at least one of the first valve and the second valve undergo an oil can valve deflection rate. The hydraulic lash is configured to selectively transmit force between the first rocker arm and the valve bridge, and where the hydraulic lash adjuster is normally in the open configuration, and where the hydraulic lash adjuster changes from the open configuration to a closed configuration at a critical velocity that is greater than the oil can valve deflection rate.
    Type: Grant

  • Patent number: 10001078
    Abstract: A cooling jacket is formed at least in part within the cylinder head mounted on an engine block defining one or more piston cylinders and one or more intake and exhaust ports in communication with each piston cylinder. The cooling jacket includes a first passageway, a second passageway and a turbulence chamber. The first passageway extends from a first flow passage and intersects the turbulence chamber at a first angular position, and the second passageway extends from a second flow passage and intersects the turbulence chamber at a second angular position different from the first angular position. A swirling action is imparted to fluid media passing through the turbulence chamber.
