See full text

A piston can include a skirt, a crown, and a cooling gallery. The skirt can have an upper body portion. The crown can be formed at the upper body portion. A wall can be formed underneath the crown so as to define a cooling gallery within the piston. The cooling gallery includes cooling gallery peripheral portion and a cooling gallery central portion. The cooling gallery can be configured to receive and to retain an amount of cooling fluid and to cause movement thereof within the cooling gallery between a cooling gallery peripheral portion and a cooling gallery central portion as the piston travels between top dead center and bottom dead center so as to cool both the piston outer region and the piston center region.
