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 19):
The piston of  claim 18 , wherein said ring grooves are spaced from one another by lands, said lands include a top land depending from said upper surface and having an axial thickness of less than 3% of said bore diameter, and a second land spaced from said top land by one of said ring grooves and having an axial thickness of less than 3.5% of said bore diameter;\n said hollowed regions extend to within 2 mm of said undercrown surface; each of said hollowed regions is bridged by a pair of pin boss piers, each of said pin boss piers having a thickness of less than 9.5% of said bore diameter; said projected skirt area is 27% to 34% of said total piston bore area; each of said skirts includes a chord width of 30% to 60% of said bore diameter, said skirts increase in width from said chord width to said piston crown, and said skirts increase in width from said cord width to a lower end of said skirts; said skirts include panels inwardly or outwardly curved from a plane by at least 0.7 mm and skirt wings projecting beyond said panels by more than 1 mm; and further including at least one stiffening rib disposed along an undercrown surface of said piston crown, and/or one of said skirts; and a coating formed of manganese phosphate disposed on said inner faces of said pin bosses forming said pin bores.
