Abstract

A torque increasing opposite direction engine employs not a combustion pressure but a high pressure medium by using a differential shifting distance and velocity per angle and a differential equivalent distance of a crank radius depending on a crank angle to thereby have a common joining section of two pistons reciprocating each other in such a way that each upper dead point of two pistons presents in the upper dead point of any one piston in an opposite site to reduce a volume of the combustion chamber in burning. The inventive crank radius is same or different and a suction and an exhaust valves are positioned to a site away from an upper dead point of the piston located at the upper dead point in burning. When one piston is an upper dead point another piston is past the upper dead point. When the equivalent distance is large, a combustion pressure in a narrow space is increased by narrowing the distance between two pistons, thereby increasing a generated torque.
