Abstract
Piston for an internal combustion engine having an upper face which forms a part of an expandable combustion chamber. The piston is provided with a cavity or deep depression formed in the upper face to promote fuel-air mixing as well as to improve the combustion process within said combustion chamber. The cavity is formed within a cup-like insert member, so positioned within the piston body that the cup-like insert is substantially spaced or insulated from the piston body, thereby avoiding or minimizing heat loss to the piston walls.
