Metal, preferably steel piston for internal combustion engine has shaft with wall of carbon material, at least in areas along its periphery

摘要

The metal, preferably steel piston (10) is for an internal combustion engine and has a shaft with a wall of carbon material, at least in areas along its periphery. In areas, the shaft has recesses, in which at least one slide component (14) is inserted. The shaft on the pressure and/or counter pressure side is so recessed that a comparatively narrow frame (16) remains, in which a large-surfaced slide component is inserted.
