摘要： A variable length connecting rod (12) has a first locking mechanism (36) for releasably locking connecting rod parts in a first effective length setting (FIG. 7) for the rod, and a second locking mechanism (38) for releasably locking the connecting rod parts in a second effective length setting to change the compression ratio for an engine cylinder. When a length change is to be made, hydraulic fluid unlocks a locked one of the locking mechanisms, allowing inertial force to effect the length change during an engine cycle. At completion of a length change, the other locking mechanism automatically unlocks.

摘要： A variable length connecting rod assembly for imparting a variable compression ratio to an internal combustion engine. The assembly contains a first part (22; 72), a second part (20; 74), and a third part (34; 70) assembled together to form the large end of the connecting rod assembly and provide a variable length for the connecting rod assembly. The first part is a semi-circular cap. One (20; 74) of the second and third parts is fastened tight to the first part (22; 72). Guides (36, 38, 48; 88, 90, 92) disposed at opposite sides of the large end operatively relate the other (34; 70) of the second and third parts and the fastened parts to provide for relative sliding motion between the other of the second and third parts and the fastened parts over a limited adjustment range to change the length of the connecting rod assembly.
