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 15):
An internal combustion engine comprising:\n an engine cylinder; an engine cylinder head having an intake port substantially diametrically opposite to an exhaust port; a piston disposed in said engine cylinder, said piston having a lower skirt portion and an upper domed portion, said upper domed portion proximal to the engine cylinder head and terminating at an upper-most point at an apex; first and second channels formed in said upper domed portion in relative proximity to the intake port as compared to the exhaust port, and formed on respective first and second sides of the upper domed portion, wherein said first and second sides of the upper domed portion are defined by a reference plane that extends between the intake port and the exhaust port and that bisects the upper domed portion; and a third channel formed in said upper domed portion between the first and second channels, and formed in relative proximity to the exhaust port as compared with the intake port.
