Abstract
Official abstract text for this publication.
A piston that maintains excellent lubricating performance even when the internal combustion engine is operated in severe environments. A primer layer including a resinous material is disposed on the sliding surface of the skirt of a piston, and solid lubricating parts, preferably including silver (Ag), a silver alloy, copper (Cu), or a copper alloy are disposed on the primer layer. In the primer layer and the solid lubricating parts, a fibrous filler including metallic fibers, etc., is present so as to extend across the boundary between the primer layer and the solid lubricating parts.
First claim
Opening claim text (preview).
1 . A piston for use in an internal combustion engine, which is movable back and forth in a cylinder of the internal combustion engine, comprising: a base layer disposed on a sliding contact surface of a piston skirt, the base layer containing a resin material; a solid lubricator disposed on the base layer; and fibrous fillers that reside within and extend between the base layer and the solid lubricator. 2 . The piston according to claim 1 , wherein, assuming that a weight of the resin material is given as 100% by weight, the proportion of the fibrous fillers lies within a range from 10% to 65% by weight. 3 . The piston according to claim 2 , wherein the solid lubricator comprises at least one of silver, silver alloy, copper, or copper alloy.
