Abstract
An assembly including a connecting rod, a bushing, and a locking pin capable of providing different compression ratios in an engine is provided. The bushing is disposed in a bore of the connecting rod. An outer surface of the bushing includes a pair of notches, and an inner surface of the connecting rod includes a corresponding notch for receiving the locking pin. The notches are spaced from one another by greater than 180° and by no more than 190°. The locking pin is movable in the notch, allowing the bushing to rotate from a low compression position to a high compression position, or vice versa. The bushing has a varying thickness, and thus a center axis of an opening of the bushing is closer to the shaft of the connecting rod body when the bushing is in the low compression orientation than in the high compression orientation.
