Abstract
A piston assembly for an internal combustion engine is provided, including a piston and at least one insert. The piston includes an annular recess, a first surface, a ring belt and a skirt. The annular recess is located between the ring belt and the skirt. The insert may include a longitudinal portion and one or more opposing arms. The insert may be configured to be coupled with the piston. The arm(s) may extend laterally from the longitudinal portion and may be configured to abut the skirt, thereby orienting the insert relative to the piston. The insert may be disposed along the first surface, and aligned with the piston skirt such that the arms of the insert form a circumference about the piston skirt. The arms may at least partially enclose the annular recess at the piston skirt.
