ABSTRACT:
An internal combustion engine in which the displacement in the cylinders is automatically varied to match the power output of the engine to power requirements. One or more kinetic controllers external to the cylinders connect engine piston cross-shafts to the engine crankshaft. Each kinetic controller is capable of changing its length through the use of damped elastic components. At high RPM the engine intake and power strokes are lengthened relative to that at low RPM as controller length increases. Also at high RPM, the engine compression stroke is lengthened as controller length decreases. Thus, at higher engine RPM, greater fuel charge, higher compression, and greter power are obtained than at lower engine RPM.
