Abstract:
1. An engine with counter-rotating housing and output shaft, comprising the following combination of components: a) A 2 cycle engine block rotatably mounted to allow rotation around the crankshaft center axis, b) Two or more, simultaneously firing, cylinders radially attached to a cooperating crankcase, equally spaced around the cooperating crankshaft, each cylinder aligned to a cooperating off-set journal on the crankshaft c) a crankshaft, journaled at either end to the block, concentric with the central axis, including two or more off-set bearing surfaces, contained within the crankcase, wherein each off-set cooperatingly aligns to a corresponding cylinder d) Two or more connecting rods each journaled at one end to a crankshaft off-set surface and journaled at the other end to the crankcase side of an individual piston e) Two or more pistons each slidably received within a corresponding cylinder f) each combustion chamber arrangement including a spark plug located within the combustion chamber at full compression but not at an outer most cavity subject to centrifical force fluid ponding during crankcase rotation g) a crankcase volume which expands and contracts during operation either systematically intaking through a carburetor or similar device a measured amount of fuel/air/oil mixture into the crank case, or systematically transferring a measured amount of the same fuel/air/oil mixture to the combustion chamber through a cavity in the cylinder wall which allows the fuel/air/oil volume to bypass the piston compression rings (h) means for producing said concentric rotation and counter-rotation as a result of a process of energy conversion; whereby during operation of the engine an inertial balance is established between said output shaft and said housing by rotating in opposite directions concentrically with respect to said engine center line.
