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 1):
An internal combustion engine comprising:\n an engine cylinder having an intake port and an exhaust port; a piston disposed in said engine cylinder, said piston having a lower skirt and an upper dome; first and second diametrically opposed and identical concave channels formed on the piston upper dome; and a concave downward sloped channel formed on the upper dome, wherein the first and second diametrically opposed and identical concave channels are proximal to the intake port relative to a first reference plane that is equidistant at all points from the exhaust port and the intake port, wherein the first and second diametrically opposed and identical concave channels are equally spaced from a second reference plane that is perpendicular to the first reference plane, and wherein the concave downward sloped channel is proximal to the exhaust port relative to the first reference plane and longitudinally bisected by the second reference plane.
