ABSTRACT:
A variable length stroke piston is provided in an internal combustion engine having an engine block means including a toroidal shaped cylinder, a piston positioned in the cylinder for arcuate reciprocation therein, a piston rod means pivotally positioning the piston for movement about the center axis of the toroid defining the cylinder, a regulatory shaft positioned parallel to a crankshaft and with a connector link extending therefrom, articulated link means pivotally interconnecting the piston rod to the engine connecting rod and operatively connecting to the regulatory shaft, and means operatively connect the regulatory shaft to the accelerator controlling the engine to rotate the regulatory shaft through a controlled arc with changes in the setting of the accelerator and reduce the length of piston stroke with reduced fuel supply to the engine to maintain substantially uniform compression in the cylinder at all times.
