Abstract

See full text

A piston-crankshaft connector for an internal combustion engine can comprise a main connecting rod connected with its big end bore to a crankpin and at least one auxiliary connecting rod connected to off-axial surfaces made on the crankpin. On the piston side, the at least one auxiliary connecting rod can be attached to an upper crankpin nested within the main connecting rod, where the crankpin carries off-centred piston pin bore. Such construction can modify a piston pin bore distance relative to a main journal central axis during their rotation, which can improve the internal combustion stroke-to-stroke performance. A compression ratio can additionally or alternatively be adjusted by hydraulics acting on an entire segmented eccentric ring relative position within connecting rod bearing space via crankpin oil channels.
