  • System and method for valve seat injection
    Patent number: 10808650
    Abstract: Methods and systems are provided for implementing fluid injection through a cylinder valve seat. The engine system may include a cylinder valve with a valve head mating with a valve seat when the valve is closed. The valve seat includes an injection orifice blocked by the valve head when the cylinder valve is closed and unblocked when the cylinder valve is opened.
    Type: Grant

    Assignee: Ford Global Technologies, LLC
    Inventors: Joseph F. Basmaji, Mark Madin, William Charles Ruona, John Cornell
  • Hollow valve spring retainer
    Patent number: 10690021
    Abstract: Methods and systems are provided for a valve spring retainer of a valvetrain assembly. In one example, valve spring retainer may be at least partially hollowed and include inner cavities forming channels within a material of the valve spring retainer. Air inside the inner cavities may be fluidly coupled to air surrounding the valve spring retainer through channels. A mass of the valve spring retainer may be decreased and a cost and speed of fabrication of the valve spring retainer may be reduced by additive manufacturing.
