ABSTRACT:
A variable stroke engine includes first and second pistons mounted in respective cylinders for reciprocal linear movement. The engine also includes first, second, and third parallel crankshafts. A first connecting assembly connects the first piston to the first and second crankshafts. A second connecting assembly connects the second piston to the second and third crankshafts. Each connecting assembly includes first and second connecting rods arranged in a crossing relationship with each other. A first set of synchronizing gears establishes co-rotation of the first and second crankshafts and synchronizes a first angular phase relationship between the first and second crankshafts. A second set of synchronizing gears establishes co-rotation of the second and third crankshafts and synchronizes a second angular phase relationship between the second and third crankshafts. A phase adjustment mechanism is connected to the first and second sets of synchronizing gears to adjust the first and second angular phase relationships, thereby varying the stroke of each piston.
