Abstract:
A ferrous piston for gasoline powered engines having dimensions which achieve reduced mass and improved performance is provided. The piston crown has a thickness of less than 4 mm and includes valve pockets with an axial clearance between the valve pockets and an uppermost ring groove of less than 1.5 mm. The pin bosses have an axial thickness of less than 3.7% of a bore diameter, which is the largest outer diameter of the piston, measured between a pin bore and the crown at 1 mm from an inner face forming the pin bore. Each pin boss has a radial thickness of less than 3% of the bore diameter measured between the pin bore and a lower end of the pin boss. An undercrown surface presents a projected area of less than 45% of a total piston bore area, wherein the total piston bore area is πBD 2 /4, BD being the bore diameter.

Claim (Index 1):
A piston, comprising:\n a piston body and piston crown formed of a ferrous material; said piston crown including a crown wall presenting an upper surface for being exposed to combustion gases and an undercrown surface for being exposed to cooling oil during operation, said crown wall having a crown wall thickness extending from said upper surface to said undercrown surface, said crown wall thickness being less than 4 mm; said piston crown including a least one valve pocket formed in said crown wall; and said piston crown including a ring belt extending from said upper surface, said ring belt including a plurality of ring grooves, wherein an axial clearance between said valve pocket and an uppermost one of said ring grooves is less than 1.5 mm.
