Abstract:
Internal combustion engines having multi-stage telescoping poppet valves in lieu of conventional poppet valves are disclosed. The engines may have pistons with a skirt with a field of pockets that provide a ringless, non-lubricated, seal equivalent. The piston heads may include one or more depressions and may be domed to facilitate the movement of air/charge in the cylinder. The engines may also have non-circular, preferably rectangular, cross-section pistons and cylinders. The engines also may include a split crankshaft. The engines may use the pumping motion of the engine piston to supercharge the cylinder with air/charge. The engines also may operate in an inverted orientation in which the piston is closer to the local gravitationally dominant terrestrial body's center of gravity at top dead center position than at bottom dead center position.

Claim (Index 1):
An internal combustion engine comprising:\n an engine cylinder having a cylinder wail; a piston disposed in the engine cylinder, said piston having a skirt and a head; a combustion chamber adjacent to the piston head defined by the cylinder wall; and a poppet valve assembly disposed in said engine cylinder, said first poppet valve assembly having an outer poppet valve with a hollow stem, a lower head, and an intermediary cage connecting the hollow stem to the lower head, and an inner poppet valve having a stem and a lower head, wherein said inner poppet valve stem is slidably disposed in the outer poppet valve hollow stem, and said inner poppet valve lower head is movable within said outer poppet valve intermediary cage.
