Abstract
Upper and lower surfaces of each intake valve, an upper surface of each piston, and an interior piston facing surface of each cylinder head of an internal combustion engine are textured to create a controlled turbulence in an air-fuel mixture flowing to and entering a combustion chamber. The surface texture preferably comprises generally concentric grooves and ramps machined into the surfaces.
