Patent attributes
A piston may include a piston crown including radially inner and outer crown mating surfaces, the crown defining at least in part a cooling gallery extending about a periphery of the crown. The piston may include a piston skirt including a pair of oppositely disposed pin bosses, the pin bosses each defining a piston pin bore. The piston skirt may have a radially inner skirt mating surface cooperating along a radially inner interface region with the radially inner crown mating surface, and a radially outer skirt mating surface cooperating along a radially outer interface region with the radially outer crown mating surface such that the cooling gallery is substantially enclosed. The piston may include at least one cooling fin extending from an interior surface of the cooling gallery.
