Abstract: A piston for an internal combustion engine and method of construction thereof is provided. The piston includes a piston body having an upper combustion surface with a combustion bowl depending from the upper combustion surface. The piston body has a ring belt region configured for receipt of at least one piston ring adjacent the upper combustion surface. A cooling gallery is configured in radial alignment with the ring belt region. An annular combustion bowl rim region extends between the upper combustion surface and the combustion bowl, and a bonded seam extends from the combustion bowl rim region radially outwardly to the cooling gallery. The bonded seam has material properties exhibiting an enhanced ability to withstand the extreme temperature, pressure, stress and highly corrosive and erosive effects of the combustion gases relative to the surrounding material of the piston body.

Abstract: An improved piston for an opposed piston internal combustion engine is provided. The piston includes a piston body that extends along an axis from a crown portion to a skirt portion with a full piston skirt and to a pin boss portion. The piston body includes a plurality of ring grooves in the crown portion and at least one ring groove in the skirt portion. A wrist pin which has a length that is longer than a maximum diameter of the piston body is joined with the piston body at the pin boss portion and extends past the pin boss portion for receiving a pair of connecting rods on opposite sides of the piston body. The piston body is a monobloc piston body which is made of one integral piece or of multiple pieces that are welded or adhered together.

Abstract: A piston and method of construction is provided. The piston includes a top part fixed to a bottom part. The top part has an uppermost surface with annular inner and outer upper joining surfaces depending therefrom. The bottom part has a pair of pin bosses with pin bores aligned with one another along a pin bore axis; a pair of upwardly extending annular inner and outer lower joining surfaces and a combustion bowl wall. Inner and outer weld joints fix the inner and outer upper and lower joining surfaces to one another. An annular cooling gallery is formed laterally between the upper and lower joining surfaces. The inner weld joint joining the top part to the bottom part is located within the combustion bowl wall and configured to minimized the compression height of the piston.

Abstract: A monobloc piston assembly for an internal combustion engine is provided. The piston assembly includes a piston body which extends along an axis and is formed of at least two pieces of material which are joined together at least one friction weld joint which extends continuously through an annular shape around the axis. One of the pieces has an upper surface with a combustion bowl having a rotationally asymmetrical shape around the axis formed therein. Another of the pieces has a dome-shaped receiving surface which is rotationally symmetrical around the axis for slidingly receiving a portion of a connecting rod.
