FMC 0145 PUS -19- 89-365 Abstract The present invention contemplates a mechan- ically simply constructed mechanism located internally of a piston engine for adjustably changing the stroke of a piston over a predetermined range in response to a variety of operating control parameters. The ad- justable stroke changing mechanism provides an optimum compression ratio at each change in piston stroke and over the entire range of piston stroke provided which may be varied from one piston engine to another of different performance characteristics without requir- ing a major change in design of the stroke changing mechanism. The stroke changing mechanism includes a swing plate pivotally fixed to the engine block at one end and placed intermediate the piston connection rod and respective crankshaft pin at its other end, each of which are affixed to and translate within the swing plate as the piston is driven to reciprocate within a piston cylinder. An adjustment link is pivotally connected to the engine block at one end and to the connecting rod at its other end and at the swing plate. The adjustment link is hydraulically con- trolled and actuable to vary in length and thereby change the stroke, and concurrently the compression ratio of the piston.
