Claim Text:
1. In a variable displacement engine, a system for changing the radius of a crankpin's revolution thereby changing the displacement of the engine comprising: a portion of a crankshaft from a single or multiple cylinder engine having a first and second journal, wherein said crankshaft portion rotates about an axis of rotation; a crankpin separate from said crankshaft portion revolving about said axis of rotation and also located between said first and said second crankshaft journals wherein said crankpin is held slidably attached to said first and said second crankshaft journals through a linear motion assembly such that the crankpin distance from said axis of rotation is adjustable and moves in a straight line from said axis of rotation; a gear train including a concentric gear with respect to said axis of rotation, whereby rotations of said concentric gear with respect to said axis of rotation will control said crankpin distance from said axis of rotation through the gear train; said gear train also including one or more linear actuators attached to said crankpin, wherein activating said linear actuators by means of said gear train moves said crankpin along said linear motion assembly thereby controlling said crankpin distance from said axis of rotation.
