Internal combustion engine with balancing forces
This patent describes an internal combustion engine of the opposed cylinder type. It comprises: a crankshaft and at least one set of pistons movably connected thereto. Each piston of the one set is reciprocally mounted within a separate corresponding cylinder and rotatably drive the crankshaft during a power stroke thereof, the one set of pistons including at least a first piston and cylinder assembly mounted on one side of the crankshaft and at least a second and a third piston and cylinder assembly mounted on the other side of the crankshaft in directly opposed relation to the first piston and cylinder assembly, each of the cylinders of the second and third piston and cylinder assemblies comprising one half the displacement volume of the cylinder of the first piston and cylinder assembly, whereby vibration of the engine is substantially reduced at all running speeds.
