ABSTRACT:
An internal combustion engine having at least one piston with an adjustable stroke length. The engine includes a connecting rod attached to the piston and a crankshaft. The crankshaft has a journal portion that extends along a length that is non-perpendicular to a movement axis of the piston. The crankshaft may be moved in a longitudinal direction with respect to the piston to adjust the position of the connecting rod on the journal portion and to thereby adjust the stroke length of the piston.
