Abstract: A system includes a reciprocating engine, the reciprocating engine includes a poppet valve having a first valve end and a second valve end. The poppet valve includes a valve head having the first valve end. The valve head may open and close a fluid passageway within the reciprocating engine. The poppet valve also includes a stem extending from the valve head and having a first length. The stem has the second valve end and the second valve end is substantially opposite the first valve end. The poppet valve also includes a cavity aligned with a centerline axis of the poppet valve. The cavity includes a first region disposed within the valve head and a second region disposed within the stem, and the second region has a second length that is shorter than the first length. The poppet valve further includes a metal alloy disposed within the cavity. The metal alloy is in a liquid-phase during operation of the reciprocating engine and may transfer heat from the valve head to the stem.

Abstract: A gasket system for sealing a cover about an opening having a gasket seat thereabout is provided. The gasket seat has a number of fastener receiving elements that is greater than a number of fasteners used with the cover. The gasket may include a body having a shape configured to mate with a sealing surface of at least one of the gasket seat and the cover, the body having an open center. The gasket may also include a fastener receiving opening in the body for each of the first number of fastener receiving elements in the gasket seat, and a raised rib extending from a surface of the body adjacent to at least one of the third number of fastener-free receiving elements in the gasket seat.

Abstract: A valve guide for a reciprocating engine including a passageway that may receive a shaft of a poppet valve and an inner wall defining the passageway and having a first surface and a second surface, the first and second surfaces forming part of the passageway. The first surface includes a first material and the second surface includes a second material. The first and second materials are different. The valve guide also includes at least one mechanical lock between the first and second materials, wherein the at least one mechanical lock is disposed within the inner wall along the passageway.
