ABSTRACT:
An engine includes a block having at least one cylinder in which a piston reciprocates. The piston is connected through a piston connecting rod to a lever arm, and the lever arm is in turn connected to the eccentric crank pin of a crankshaft through a crank connecting rod. The lever arm is positioned and moved not only by the piston and crankshaft, but also by a positioning cam which bears against one end of the arm. The arrangement is such that throughout the entire power stroke the force transmitted to the crankshaft is applied through a relatively large moment arm, thus providing greater torque for the engine. The arrangement results in a relatively large angle between the crank connecting rod and the crank arm and permits greater eccentricity on the crank arm.
