Coating to reduce coking deposits on steel pistons

Coating to reduce coking deposits on steel pistons

A piston for an internal combustion engine is provided. The piston includes a coating applied to a ferrous body portion to reduce or prevent chemical bonding of carbon deposits or coking on the body portion at temperatures ranging from 200 to 400° C. The coating includes a fluoropolymer, such as pol...

description A piston for an internal combustion engine is provided. The piston includes a coating applied to a ferrous body portion to reduce or prevent chemical bonding of carbon deposits or coking on the body portion at temperatures ranging from 200 to 400° C. The coating includes a fluoropolymer, such as polytetrafluoroethylene, fluorosilane, fluorocarbon, fluoroplastic resin, and/or perfluoroplastic, and may be hydrocarbon or silicone based. The coating also has a thickness of 25 microns to 1 millimeter. The coating can be disposed on an undercrown surface, ring grooves, ring lands, pin bosses, and/or skirt sections of the body portion.
