ABSTRACT:
An internal combustion engine utilizing either an Otto or a Diesel cycle contains two opposed pistons in each cylinder. The first piston drives a crank arm which drives a crankshaft. The crankshaft, through a timing means, drives an eccentric positive-motion cam which drives a movable cylinder head piston. The positive-motion cam drives the movable cylinder head piston via two roller followers, placed on opposite sides of the axis of rotation of the cam. The first piston functions as a driving piston. The movable cylinder head piston changes the volume in the cylinder between the pistons as a function of the movement and position of the first piston.
