Zusammenfassung:A variable compression ratio piston 26 and connecting rod 18 assembly for an internal combustion engine includes an eccentric bushing 28 that carries a piston pin bushing 42 and contains a journalled portion 48 held in the rod bore 24 of the connecting rod 18. The eccentric bushing 28 can be selectively rotated between either of two rotary adjusted positions to effect a change in the height of the piston 26 relative to the connecting rod 18 and thus change the compression ratio of the assembly.
