Abstract
A variable stroke and compression ratio engine employs multiple pistons connected to a wobbler. A crank with an axis of rotation has an upper journal with a first angle relative to the axis and a lower journal with a second angle with respect to the axis. A cradle connected for rotational motion with respect to the wobbler is carried by the crank with sliding engagement to the upper and lower journals for translation between a first high eccentricity position and second low eccentricity position.
