Patent ID: 8091521

Claim:
A self-supercharging internal combustion engine comprising: (a) a primary triple piston and cylinder combination reciprocally connected to a first crankshaft, said primary triple piston and cylinder combination comprising: (i) a first piston and cylinder with intake and exhaust valves, the piston being connected to the first crankshaft in a first position; (ii) a second piston and cylinder with intake and exhaust valves, the piston being connected to the first crankshaft in a third position; (iii) a third piston and cylinder of a size which is at least double the size of the first and second pistons and cylinders, the third piston having a valve which enables air and fuel to be drawn into the third cylinder, the third cylinder being connected in alternating manner to the intake valves of the first and second pistons and cylinders, the third piston being connected to the first crankshaft in a second position between the first and third positions; (b) a secondary triple piston and cylinder combination reciprocally connected to a second crankshaft; said secondary triple piston and cylinder combination comprising: (i) a fourth piston and cylinder with intake and exhaust valves, the piston being connected to a second crankshaft in a first position; (ii) a fifth piston and cylinder with intake and exhaust valves, the piston being connected to the second crankshaft in a third position; and (iii) a sixth piston and cylinder of a size which is at least double the size of the fourth and fifth pistons and cylinders, the sixth piston having a valve which enables air and fuel to be drawn into the sixth cylinder, the sixth cylinder being connected in alternating manner to the intake valves of the fourth and fifth pistons and cylinders, the sixth piston being connected to the second crankshaft in a second position between the first and third positions; (c) the first and second crankshafts being connected by a combination of gears; said first and second crankshafts being parallel to one another; and said first crankshaft including an automatic freewheeling mechanism which enables the first crankshaft to provide positive drive on the second crankshaft, but the second crankshaft not to provide positive drive on the first crankshaft.
