A lubricant formulation which is effective to remove or prevent carbon deposits in internal combustion engines has a solvency as defined by aniline point from about 20 to about 115, a volatility (as measured by NOACK) of less than 15%, an oxidative stability (as measured by PDSC) of above 40 minutes and a base oil viscosity of above 2 and below 10 cSt. The lubricant formulation can be formed from a blend of Group III, IV and V lubricants, in particularly polyalphaolefins, alkylated naphthalenes and polar Group V base stocks such as polyol esters. The carbon deposits can be removed from the engine piston by simply running the engine with the lubricant for one required cycle, or can be used continuously in the engine to prevent buildup.

Lubricant for preventing and removing carbon deposits in internal combustion engines

The introduction of nanostructures in a liquid provides a means for changing the physical and/or chemical properties of the liquid. Improvements in heat transfer, electrical properties, viscosity, and lubricity can be realized upon dispersion of nanotubes in liquids. Stable dispersions of nanostructures are described and surfactants/dispersants are identified which can disperse nanostructures in petroleum liquid medium. The appropriate dispersant is chosen for the selected nanostructure material and the oil based medium and the dispersant is dissolved into the liquid medium to form a solution. The nanostructure is added to the dispersant containing the solution with agitation, ultrasonication, and/or combinations thereof. Nanostructures dispersed in a fluid form a nanofluid utilized as a shock absorber oil whereby the nanostructures serve to improve the viscosity index of the fluid or more particularly the shock absorber oil in the form of a lubricant additive.

This invention relates generally to water resistant peelable protective and decorative clear or pigmented coating compositions and, more specifically, to aqueous and solvent based, polymeric coating compositions which form a protective and/or decorative coating and is removably adheres to a variety of substrates, including automotive paints, metals, glass, vinyl, plastics, concrete, natural and synthetic elastomers, and ceramics. The coatings can be either a flat film on the substrate, or a three-dimensional expandable foamy coating, and can be readily peeled off from the substrate as a whole piece. The coatings may be formulated for temporary or long-term protection depending upon the application. The peelable coatings can be applied as a paint, paste, film, or expandable foam cord whereby the expansion of the foam can be controlled by the formulation and applicator.

The present invention relates generally to the field of release agents commonly in uses in preventing asphalt and other sticky compounds such as rubbers from sticking to the transporting vehicles such as dump truck beds and processing tools, and equipment, and more particularly to a novel biodegradable release agent applied to metal surfaces prior to use for promoting free release of sticky hot-mix asphalt materials from the metal tools and equipment used in road construction applications.
