摘要： A low-friction piston construction for use in an oil-fed cylinder bore with the piston skirt relieved to define lands that are coated with SFL (graphite, MoS.sub.2, BN, and a special expoxy resin). A method of making such piston construction including provision of asperities on the skirt wall onto which the SFL coating is thermally sprayed and formation of small pockets at the mouth of the asperities to additionally act as oil replenishing reservoirs. A method of using such piston construction in an engine which comprises provisions of a slightly increased gap between the piston and cylinder wall and formation of a transferred SFL coating from the piston to the cylinder wall resulting in two polished microsmooth mating coatings, each attractive to oil films.

摘要： A method of flexibly manufacturing engine blocks by first bonding an extruded tube liner insert, of a given thickness (1-15 mm), to a fixed configuration block, the liner insert having been coated with an anti-friction wear-resistant coating having a controlled standard thickness, and secondly bonding an extruded tube liner insert of a different thickness (again selected from 1-15 mm) to another of the fixed configuration blocks, the second liner insert having been coated with the same type of anti-friction wear-resistant coating in essentially the same controlled standard thickness. The common sized engine block can have (i) identically shaped circular cylindrical bore walls or (ii) ovoid cylindrical bore walls with the liner insert having an interior surface shape selection varying between circular to ovoid. The block and liner insert may be both made of aluminum. To promote wear-resistant and lubricant qualities, the coating may contain a mixture of hard particles (such as stainless steel, nickel, chromium or vanadium) and solid lubricant particles such as oxides of iron having controlled oxygen, BN, LiF, NaF.sub.2 or a eutectic of LiF/NaF.sub.2.

摘要： A piston and ring assembly operative within a cylindrical bore wall to retain fluid to one side of the assembly, comprising a piston having at least one annular stepped groove in the side wall of the piston, the groove being stepped into uppermost and lowermost spaces with the uppermost space having the greatest depth; at least two split compression rings in the groove, effective to each substantially annularly engage the bore wall, the rings having mating surfaces superimposed one upon another and having their split ends out of superimposed alignment, and a solid lubricant that coats essentially all of the groove and constitutes the non-mating surfaces of the superimposed rings. Pressure of the retained fluid forces the rings together to act in unison and seal jointly against both the step and a side of the groove opposite the retained fluid. The solid film lubricant assists in eliminating freezing of the rings against the groove sides, increasing ring fatigue life, enhancing ring tension and reducing engine emissions.
