PISTON WITH ANTI-CARBON DEPOSIT COATING AND METHOD OF CONSTRUCTION THEREOF

摘要

A piston and method of construction are provided. The piston includes a piston body having an upper combustion surface configured for direct exposure to combustion gases within a cylinder bore with an undercrown surface located beneath the upper combustion surface. The piston body also includes a ring belt region configured for receipt of at least one piston ring adjacent the upper combustion surface with a cooling gallery configured radially inwardly and in substantial radial alignment with the ring belt region. The piston further includes a non-stick material contained in or bonded to at least one of the undercrown surface and at least a portion of the cooling gallery, wherein the non-stick material inhibits the buildup of carbon deposits thereon.
