Patent number: 11434447Abstract: 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.Type: GrantFiled: May 16, 2016Date of Patent: September 6, 2022Assignees: Valvoline Licensing and Intellectual Property, LLC, Imperial Innovations LimitedInventors: Anant S. Kolekar, Andrew V. Olver, Adam E. Sworski, Frances E. Lockwood, Gefei Wu, Xiurong Cheng

Patent number: 10927321Abstract: A traction fluid comprising a blend of 2,3-dicyclohexyl-2,3-dimethylbutane (HAD) and 2,3-dicyclohexyl-2,3-dimethylbutane (iso-HAD) is found to have a lower viscosity at low temperatures when compared to a traction fluid having only HAD or only iso-HAD as a base fluid with no compromise to traction coefficient. The traction fluid may comprise additives. The traction fluid usually comprises HAD:isoHAD between about 8:1 to about 1:3. Further, the HAD:iso-HAD traction fluid blend is produced by a method of simultaneous co-production of hydrogenated HAD and hydrogenated iso-HAD from an alpha styrene dimer and an iso-HAD precursor with a yield of about 90% in a method that does not require a purification step.Type: GrantFiled: July 10, 2020Date of Patent: February 23, 2021Assignee: VALVOLINE LICENSING AND INTELLECTUAL PROPERTY LLCInventors: Gefei Wu, Rajkumar Rajule, Ning Ren, Jesse Dambacher, Frances Lockwood

Patent number: 10774287Abstract: Traction fluid additive combination that is usable with any traction fluids base stock is provided. To optimize the traction, low temperature viscosity and shear stability performance, a combination of a polyisobutene and a polymethacrylate may be added to a base oil to obtain a traction fluid with good low temperature viscosity without degrading the shear strength properties of the fluid. To minimize foaming of the traction fluid, a combination of one, two, or more anti-foaming agents may be added to the fluid in addition to a standard additive package.Type: GrantFiled: March 6, 2019Date of Patent: September 15, 2020Assignee: VALVOLINE LICENSING AND INTELLECTUAL PROPERTY LLCInventors: Gefei Wu, Ning Ren, Frances E.

Patent number: 10323207Abstract: 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.Type: GrantFiled: November 20, 2014Date of Patent: June 18, 2019Assignees: Imperial Innovations Limited, Valvoline Licensing and Intellectual Property LLCInventors: Anant S.
