Connecting rod for a variable compression engine |
摘要 |
A variable length connecting rod 13 for changing a compression ratio of an engine is provided. The connecting rod 13 includes a first locking assembly 36 for locking the connecting rod 13 in a first effective length setting corresponding to a high compression ratio. The connecting rod 13 further includes a second locking assembly 38 for releasably locking the connecting rod 13 in a second effective length setting corresponding to a low compression ratio. When a length change is initiated, hydraulic fluid unlocks one of the locking assemblies 36, 38, allowing inertial force to effect the length change during an engine cycle. At completion of a length change, the other locking assembly 36, 38 automatically locks. The locking assemblies 36, 38 are self-contained units that are assembled to a bearing retainer 24.
