Abstract:
Cooperatively shaped piston and cylinder head arrangements for internal combustion engines are disclosed. The piston may have a domed head with one or more curved exhaust channels and inlet channels formed therein. The piston cylinder may have curved surfaces that are exact or close inverse or negative counterparts to the curved surfaces of all or part of the domed head, including the exhaust channels, and/or inlet channels formed on the piston.

Claim (Index 23):
An internal combustion engine piston comprising:\n a lower skirt; an upper dome having an apex; first and second diametrically opposed and concave channels formed on the upper dome below the apex; and a concave downward sloped channel formed on the upper dome between the first and second diametrically opposed concave channels, wherein the first and second diametrically opposed and concave channels are equally spaced from a first reference plane that is coextensive with a reference center axis for the piston skirt, and off-center relative to a second reference plane that is perpendicular to the first reference plane and coextensive with the reference center axis for the piston skirt, and wherein the concave downward sloped channel is centered relative to the first reference plane, and off-center relative to the second reference plane.
