This invention relates to new and useful improvements in the mechanism comprising the piston and piston connecting rod of the reciprocating internal or external combustion engine systems. Pressure forces acting on the piston face are concentrated in an intermediate linkage and subsequently transmitted to the connecting rod which reacts as a three-force member in the form of a second-class lever system. The purpose of the invention is to increase the mechanical efficiency of such systems during the period when the crank position is near top-dead-center. This is accomplished by introducing piston forces tangentially to the longitudinal axis of the connecting rod in a manner which increases the net rotative effort applied to the crankshaft.
