PISTON HEAD AND PISTON HEAD ASSEMBLY

Abstract: a piston head includes an upper portion that includes an upper wall, an outer wall extending around a periphery of the upper wall, and an inner wall disposed radially inward of the outer wall. a cooling gallery is defined between the outer wall and the inner wall. the piston head further includes a lower portion extending downward from the upper portion. the lower portion includes an upper surface and a skirt extending from the upper surface in a direction away from the upper portion. the skirt defines a pin bore that receives a pin. the pin bore is centered around a pin bore center axis. a portion of the skirt between the pin bore center axis and a skirt reference axis has a vertical profile that is substantially non-linear. the skirt reference axis is orthogonal to the pin bore center axis and parallel to the upper surface.
