Piston cooling arrangement

Abstract

A piston includes a skirt portion including a skirt sidewall centered about a piston center axis, and a crown portion positioned on an end of the skirt portion. The crown portion and the skirt portion cooperate to define a piston cavity. The crown portion includes a crown sidewall continuous with the skirt sidewall, a rim continuous with the crown sidewall and extending inward from the crown sidewall, an inner wall extending inward from the crown sidewall, and a bowl including a bowl wall extending from the rim to the inner wall. The crown sidewall, the rim, the inner wall, and the bowl wall cooperate to define a passageway extending around the bowl. The inner wall defines a channel extending at a non-zero angle relative to the piston center axis. The channel is in fluid receiving communication with the passageway and in fluid providing communication with the piston cavity.
