ABSTRACT:
A mechanism for varying the stroke length of an internal combustion engine during each cycle of operation includes a gear set with at least two gear members with a first gear member being non-rotatably mounted to the engine block and a second gear member being operatively engaged with the first gear member and having teeth formed on an inner surface thereof with the gear ratio of the gear set being 1:2 to produce a variable stroke length throughout the engine operating cycle.
