Abstract
Various embodiments (20; 50; 50; 120) of variable length piston and connecting rod assemblies for imparting a variable compression ratio to an internal combustion engine. The embodiments incorporate novel arrangements of relatively movable parts (32, 34; 60, 62; 84, 86; 124, 126) related by various elastomeric elements (38; 58; 96, 104; 136) and oil passages (42; 116, 118; 140, 142) to change compression ratios.
