Patent number: 5478463Abstract: A method, composition and filter for reducing the presence of sludge or varnish precursors in a lubricating oil circulating within an internal combustion engine. The lubricating oil containing sludge or varnish precursors is contacted with discrete particles of an oil insoluble, oil wettable compound having an antioxidant functional group and/or a dispersant functional group, which are capable of complexing with sludge or varnish precursors. Preferably the compounds comprises a crosslinked amine having ethylene amine functionality. The starting polyethylene amines have a number average molecular weight in the range of about 100 to about 60,000, preferably 200 to 250 and are crosslinked with a silicon oxide, silane, silicate, epoxide, quinone, or phenol-formaldehyde crosslinking agent.

Patent number: 5164101Abstract: Piston deposits resulting from neutralizing combustion acids present in the lubricating oil circulating within the lubrication system of an internal combustion engine are reduced or eliminated by first cntacting the acids with a soluble weak base in the piston ring zone of the engine to form soluble neutral salts containing the weak base and the combustion acids. Thereafter, the neutral salts are contacted with a heterogenous strong base immobilized within the lubrication system but outside of the piston ring zone. The strong base displaces the weak base from the neutral salts, returning the weak base to the oil for recirculation to the piston ring zone for further use. The remaining strong base/combustion adic salts are immobilized as deposits with the strong base rather than on the piston. In a preferred embodiment, trioctadecyl amine is the weak base and magnesium oxide is the strong base.Type: GrantFiled: March 5, 1991Date of Patent: November 17, 1992Assignee: Exxon Research and Engineering Co.Inventors: Darrell W.
