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 5):
A piston, comprising:\n a piston body and piston crown formed of a ferrous material; said piston crown including a crown wall presenting an undercrown surface for being exposed to cooling oil during operation; said piston body presenting a bore diameter being the largest outer diameter of said piston body; said piston body including a pair of pin bosses extending from said piston crown, each of said pin bosses including an inner face forming a pin bore surrounding a pin bore axis; each of said pin bosses having an axial thickness of less than 3.7% of said bore diameter measured between said pin bore and said piston crown at 1 mm from said inner face forming said pin bore; each of said pin bosses having a radial thickness of less than 3% of said bore diameter measured between said pin bore and a lower end of said pin boss; said piston crown including a least one valve pocket formed in said crown wall; 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; and wherein said piston does not include a closed oil cooling gallery along said undercrown surface,  6 , The piston of  claim 5 , wherein said pin bores each have an upper half surface extending upwardly from said pin bore axis, said upper half surface presents a projected pin bore area being less than 10% of a total piston bore area, said total piston bore area being \u03c0BD 2 /4, wherein BD is said bore diameter.
