<p>A reciprocating piston internal combustion engine is disclosed having an eccentric (16) arranged between each piston (10) and its connecting rod (12) and a spring (22) for applying a biassing torque to urge the point of maximum eccentricity on the eccentric (16) to a rest position lying on a line transverse to the longitudinal axis of the connecting rod. The eccentric is free to oscillate about the rest position as a result of the forces acting between the piston (10) and the connecting rod (12) during engine operation and this varies dynamically the instantaneous effective length of the connecting rod.</p> |
