Abstract:
The present invention relates to a treatment to be used as an additive to a stock lubricant. The present invention may comprise an amount of a base fluid or other fluid, such as polybutylene, naphthenic oil, or a group III base fluid and a bismuth in a non-active sulfur. The present invention formula may further comprise one or more of a defoamer, a friction modifier, a detergent, a dispersant, and a polyol ester. Bismuth may be a particularly good sacrificial material for use as a lubricant additive because it is a heavy weight inorganic material that becomes soft at high temperatures. The preferred embodiment may utilize approximately 60% of the base fluid and approximately 30% of the bismuth in a non-active sulfur (approximately 15%-18% by weight bismuth) by volume. The treatment can be useful as a additive to a motor oil, a hydraulic lubricant, a gear lubricant, a diesel oil lubricant, or a compressor lubricant.
Abstract:
An additive composition comprising: (a) an ashless dispersant comprising an acylated nitrogen compound; and (b) a carboxylic acid, or an ester of the carboxylic acid and an alcohol wherein the acid has from 2 to 50 carbon atoms and the alcohol has one or more carbon atoms provides an improvement in the lubricity of fuel oils and exhibits improved solubility in the fuel oil.
Abstract:
The invention discloses a fuel oil composition comprising a major proportion of a liquid hydrocarbon middle distillate fuel oil, from 1 to 100 ppmw based on the composition of a polyoxyalkylene glycol dehazer and from 1 to 100 ppmw based on the composition of an organosilicone antifoam additive, wherein before mixing of the organosilicone antifoam with any other component of the fuel oil composition, the organosilicone antifoam additive is heated at a temperature of at least 40° C. for a sufficient period of time to achieve improved antifoam properties of the fuel oil composition; a process for the preparation of such a fuel oil composition; and a method of fuelling a road vehicle with such a composition.
Abstract:
The present invention relates to an additive for a fuel for the neutralization of SO2 and/or SO3 in the exhaust gases of internal combustion engines operated with the fuel, and a method for the neutralization of SO2 and/or SO3 in the exhaust gases of internal combustion engines. According to the invention, the additive contains one or more metal compounds soluble in the fuel. In the combustion of the fuel these compounds form stable sulfates which are present in solid particles in the exhaust gas. The method of the invention is characterized in that one or more of these additives are added to the fuel and the combustion of the fuel takes place in an oxidizing atmosphere.
Abstract:
A mixture contains(a) from 10 to 90% by weight of at least one imide of a copolymer based on an .alpha.-olefin and an ethylenically unsaturated dicarboxylic acid and a polyamine and(b) from 10 to 90% by weight of at least one reaction product of a poly(C.sub.2 -C.sub.20 -carboxylic acid) having a tertiary amino group with secondary aminesand is used as a paraffin dispersant in mineral oil middle distillates.
Abstract:
The lubricity of low sulphur fuels is enhanced by incorporation of a lubricity enhancing additive in combination with a polyoxyalkylene compound.
Abstract:
Reaction products of polyisobutenes having an average degree of polymerization P of from 10 to 100 and a content E of from 60 to 90% of double bonds which can react with maleic anhydride, E=100% corresponding to the theoretical value for the case where each molecule of the polyisobutene has such a reactive double bond, with oxides of nitrogen or mixtures of oxides of nitrogen and oxygen, are suitable as additives for fuels, in particular for gasoline engines, and for lubricants.
