ABSTRACT:
An improved variable stroke internal combustion engine (10) is disclosed. The power stroke and exhaust stroke of the engine are relatively longer than the intake stroke and compression stroke for increased power output from the engine (10). A connecting rod (40) is pivotally connected to the piston (16) and a trunnion assembly (28). The trunnion assembly is rotatably mounted to a journal (24) on the crankshaft (20). A control shaft (46) is rotatably mounted within the engine and connected to the crankshaft (20) so that the control shaft rotates at one-half the angular velocity of the crankshaft. A control link (52) is rotatably mounted on a journal (50) of the control shaft (46) with its opposite end being pivotally connected to the trunnion assembly (28).
