Abstract
Official abstract text for this publication.
A piston, comprising a crown, an insert having an outer ring, an inner ring, and at least one interconnection between the outer ring and the inner ring, and a skirt integrally formed with the crown through the insert so that the crown and skirt are made from a type of aluminum and the insert is made from a material other than aluminum.
First claim
Opening claim text (preview).
The invention claimed is: 1. A piston, comprising: a crown; an insert having an outer member comprising a channel through a thickness of the outer member, an inner member, and at least one interconnection between the outer member and the inner member; and a skirt integrally formed with the crown through the insert, wherein the crown and skirt are made from a type of aluminum and the insert is made from a material other than aluminum. 2. The piston of claim 1 , further comprising a groove in the outer member in the same plane as a circumference of the piston. 3. The piston of claim 2 , further comprising a plurality of interconnections between the outer member and the inner member. 4. The piston of claim 3 , further comprising an aperture through the inner member. 5. The piston of claim 1 , further comprising an aperture through the inner member. 6. The piston of claim 5 , further comprising a plurality of interconnections between the outer member and the inner member. 7. The piston of claim 1 , further comprising a plurality of interconnections between the outer member and the inner member. 8. The piston of claim 7 , wherein each of the plurality of interconnections is equally spaced about a common center of the outer member and the inner member. 9. The piston of claim 7 , further comprising an aperture through the inner member. 10. The piston of claim 1 , further comprising a channel along a radial direction of the outer member and a groove in the outer member. 11. The piston of claim 1 , wherein the piston is operatively connected to an engine for a vehicle. 12. The piston of claim 1 , wherein the outer member is an annular shape. 13. The piston of claim 12 , wherein the inner member is an annular shape. 14. A piston, comprising: a crown; an insert having an outer member comprising a channel through a thickness of the outer membercomprising a channel through a thickness of the outer member and a groove in the outer member, an inner member, and a plurality of interconnections between the outer member and the inner member, wherein the at least one interconnection is angled so that the inner member and the outer member are not in the same plane; and a skirt integrally formed with the crown through the insert, wherein the crown and skirt are made from a type of aluminum and the insert is made from a material other than aluminum. 15. The piston of claim 14 , wherein the piston is operatively connected to an engine for a vehicle. 16. The piston of claim 14 , wherein the outer member is an annular shape. 17. The piston of claim 16 , wherein the inner member is an annular shape.
