PROBLEM TO BE SOLVED: To provide a system and method of manufacturing fluid cooled poppet valves of a reciprocating engine.SOLUTION: A reciprocating engine 10 includes a poppet valve 46 having a first valve end 140 and a second valve end 142. The poppet valve includes a valve head 108 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 valve stem 110 extending from the valve head and having a first length. The valve 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 126 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 valve 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 valve stem.SELECTED DRAWING: Figure 2 |
