  • Publication number: 20170029734
    Abstract: 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.

  • Publication number: 20160257906
    Abstract: A silicone modified lubricant includes a Group I, II, III, IV or V base oil in combination with a minor amount of a silicone oil. Further, the lubricant includes a dispersant such as a dispersant olefin copolymer which maintains the silicone oil dispersed in the base oil. The silicone oil reduces the surface tension of the lubricant thereby reducing power loss. Preferably the lubricant formation has a surface tension less than 28 mN/m, making it particularly suitable for dip lubrication systems.

  • Patent number: 9360103
    Abstract: Energy loss in a dip lubrication system is reduced by reducing the immersion depth of the gear within a pool of oil. This can be accomplished by increasing the pressure within the dip lubrication system which effectively reduces the flow rate of the oil so that the oil remains separated from the oil pool for a longer period of time thereby reducing the oil level and the immersion depth of the gear within the oil pool. Alternately, this can be accomplished by substituting a higher density gas for air which has the same effect. In a third embodiment the immersed gear includes wind vanes that direct air against the oil pool creating a trough which effectively reduces the immersion depth of the gear within the oil pool.

  • Publication number: 20150148272
    Abstract: A gear or engine oil or other type of lubricant, which effectively reduces churning losses in a dip lubrication system or any lubrication system where churning loss occur has a surface tension less than 28 mN/m and viscosity less than 400 mPa-sec at 25° C. (about 500 cSt at 25° C.). Formulations include Group I-IV base oil, in combination with an amount of silicone oil effective to decrease the surface tension of the oil, thereby reducing churning losses. When the base oil is prominently Group III, the coefficient of friction of the gear oil is also reduced.

  • Patent number: 8258206
    Abstract: A hydrophobic coating has been made for use on interior pipe surfaces, exterior boat surfaces, and in many other applications, to reduce drag in fluid flow, thus providing an energy savings. The coating utilizes a blend of organic and/or inorganic polymers with hydrophobic nanoparticles of fumed silica and/or titania in a solvent. The coating solves the problem of poor resistance to UV light and/or abrasion found in previous coatings of similar nature. The coating of the present invention can be made to be translucent and nearly transparent whereas previous coatings of comparable hydrophobicity have all been white or opaque. The coating can be applied in a single application by an easy spraying method and the super hydrophobic property can be achieved by drying the film at room temperature for 5 to 10 minutes. A preferred coating has good resistance to UV light and some resistance to abrasion.

  • Patent number: 7926617
    Abstract: A method and apparatus for changing engine motor oil more quickly and simply than previously existing methods. To change oil on a gasoline or diesel engine, the conventional oil filter is removed and an adapter is screwed in its place. An inlet oil port of the adapter connects with the oil filter inlet line and an outlet port of the adapter connects to the oil filter outlet line. The adapter top is sealed with a recessed O-ring extending around the periphery so that oil can be pumped through the adapter into and out of the engine without leaking. The adapter inlet and outlet ports are connected by hoses/tubes to an external container with its own internal piston. The engine is turned on to idle and the engine oil pump pumps used oil from the oil pan out through the adapter outlet port into the external container.

  • Publication number: 20100022422
    Abstract: A process for producing a nanographite dispersion in a fluid wherein the thermal conductivity of the dispersion is enhanced from the base fluid by more than 10% for a 1% graphite dispersion. A high purity graphite with high crystallinity and reduced surface damage and oxidation is selected as the starting material. The starting material is subjected to a process of wet media milling in the presence of dispersant and solvent fluid. The mill temperature is controlled to control and reduce surface damage to yield a nanographite with flake shape and controlled aspect ratio until a particle size average of 300 nm diameter and 50 nm is obtained. The process recycles a portion of the milled material to increase the ratio of small particle distribution to large particles in an intermediate product with small and large particle bi-modal distribution. The large particle distribution is removed by a separation process such as centrifugation or filtration.

  • Publication number: 20090131289
    Abstract: The introduction of nanotubes 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; however, nanotubes behave like hydrophobic particles and tend to clump together in liquids. Methods of preparing stable dispersions of nanotubes are described and surfactants/dispersants are identified which can disperse carbon nanotubes in aqueous and petroleum liquid medium. The appropriate dispersant is chosen for the carbon nanotube and the water or oil based medium and the dispersant is dissolved into the liquid medium to form a solution. The carbon nanotube is added to the dispersant containing the solution with agitation, ultrasonication, and/or combinations thereof.

  • Publication number: 20090018249
    Abstract: A hydrophobic self cleaning coating composition that can be applied by conventional methods such as by spraying the composition onto a surface forming creating a wet and dry dirt repellent coating on the surface. The coating utilizes hydrophobic nanoparticles of fumed silica and/or titania in a solvent which evaporates at ambient temperature. The coating solves the problem of poor resistance to UV light, opaque appearance, and/or abrasion found in previous coatings of similar nature. Virtually transparent coating are produced as compared to conventional coatings of comparable hydrophobicity which are typically white or opaque. The coating can be applied by a single and easy spraying method and the super hydrophobic property can be achieved by drying the film by evaporation of the solvent at ambient temperature for 5 to 10 minutes.
