Patent ID: 7467613

Claim:
An internal combustion engine, comprising: a first piston system including: an engine block; a cylinder through the engine block; a piston with piston rings, disposed within the cylinder, the piston including a cavity therein the underside; a stump member, disposed within the cylinder and sized to be received by the cavity therein the underside of the piston, and having a bore through the center to a direction of travel of the piston; a connecting rod, with a first end in direct communication with piston, and a second end in direct communication with the crankshaft; a first combustion chamber within the cylinder defined between the piston, the cylinder, and an upper engine head; a second combustion chamber within the cylinder defined between the piston, the cylinder, the stump member, and a cylinder floor; an inlet port disposed through the engine block orthogonal to a direction of travel of the piston; an outlet port disposed through the engine block orthogonal to the direction of travel of the piston; a sparkplug/fuel injector port disposed through the engine block orthogonal to the direction of travel of the piston; a plurality of multiple heads including: a plurality of inlet ports and outlet ports; a plurality of valves, valve springs, valve stem guides, and retainer locks; an engine head attached to the top of engine block with valves in the direction of piston travel, and in direct communication with first combustion chamber system; an engine side rack/side head, attached to side of an engine block; having recessed valve seats, recessed valves, and in direct communication with second combustion chamber system; an engine side rack/side head, having inlet valve ports and outlet valve ports, in direct communication with inlet ports and outlet ports disposed through the engine block orthogonal to the direction of travel of the piston; and an engine side rack/side head, with an spark plug/fuel injector orifice port, in direct communication with spark plug/fuel injector orifice port disposed through the engine block orthogonal to the direction of travel of the piston.
