Abstract:
An aluminum piston including a cooling gallery with titled inner and outer side walls is provided. The piston comprises a ring belt with a ring grooves, and an iron insert is disposed in a top one of the ring grooves. To reduce stress and mass of the piston, material located under the iron insert is removed, so that the outer side wall of the cooling gallery is tilted toward the center axis. The inner side wall of the cooling gallery is tilted away from the center axis.
