The selection and utilization of particularly characterized hydrocarbon oils as detergent carriers reduces intake valve deposits and combustion chamber deposits, in comparison to conventionally used carrier fluids.Type: ApplicationFiled: August 9, 2006Publication date: February 14, 2008Inventors: Lawrence J. Cunningham, Beth A. Sloane, Dennis J. Malfer, May Duffield Thomas

Patent number: 6488724Abstract: The additive described essentially comprises a selected alkoxylated fatty amine or fatty amine derivative and a special metal salt compound, preferably a metal soap. This additive for heavy oils effects a good emulsification or dispersion of asphaltenes and other higher-molecular weight compounds and, in addition, inter alia, increased storage stability, improved pumpability due to decreased viscosity of the oil and longer service lives of the filter systems. In addition, it also effects enhanced combustion of the heavy oils. The effective amount of additive in these oils is 2 to 2000 ppm. The oils described are suitable, in particular, as furnace fuel for industrial plants and power stations and as engine fuel for marine engines.Type: GrantFiled: October 27, 1997Date of Patent: December 3, 2002Assignee: Clariant GmbHInventors: Günther Hertel, Michael Feustel, Hakan Byström, Geoffrey Richards

Patent number: 6458172Abstract: The present invention is directed to fuel additive compositions of detergents combined with fluidizers and to hydrocarbon fuel compositions containing these fuel additive compositions. The fuel additive compositions of the present invention combine a Mannich detergent, formed from reaction of an alkylphenol with an aldehyde and an amine, with a fluidizer that can be a polyetheramine or a polyether or a mixture thereof and, optionally, with a succinimide detergent. Fuel compositions containing these fuel additive compositions are very effective in reducing intake valve deposits in gasoline fueled engines, especially when the weight ratio of detergent(s) to fluidizer(s) is about 1:1 on an actives basis.Type: GrantFiled: March 3, 2000Date of Patent: October 1, 2002Assignee: The Lubrizol CorporationInventors: Malcolm G.
