摘要： Methods and apparatus are provided for operating a free-piston linear alternator. The apparatus includes a linear machine having first and second coils wound around a path for a linearly-moving mass and a rotating machine having a rotating mass and third and fourth coils. The first coil is coupled to the third coil, and the second coil is coupled to the fourth coil, such that movement of the linearly-moving mass with respect to the first and second coils imparts a first magnetic field upon the rotating mass via the third and fourth coils. Further, movement of the rotating mass with respect to the third and fourth coils creates a second magnetic field upon the linearly-moving mass to position the linearly moving mass for combustion.

摘要： A free piston engine utilizes a shuttle frame external to combustion chambers to rigidly link shuttle parts reciprocating along a centerline. If the shuttle parts are spaced apart along the centerline, the shuttle frame may be struts extending from the shuttle parts and linked by rods. Alternatively the shuttle parts are within a tubular shuttle frame that forms part of the combustion chamber boundary. If one shuttle part is arranged around the other with both centered about the centerline, the shuttle frame may include an annular plate between a cylindrical inner shuttle part and an annular outer shuttle part. Alternatively the shuttle frame may include an inner tube with a cylindrical inner shuttle part within the inner tube, and an outer tube with an annular outer shuttle part arranged between the inner and the outer tubes so that the shuttle frame forms part of the combustion chamber boundary.
