Abstract:
This invention relates to compositions which are useful as additives in lubricants and fuels, and more particularly, to additives which are chlorine-free or contain only minor amounts of chlorine. More particularly, carboxylic compositions are described which are prepared by reacting a terpolymer derived from a mixture of monomers comprising ethylene, an alpha-olefin containing 3 to about 20 carbon atoms, and a non-conjugated polyene with an alpha,beta-monounsaturated dicarboxylic acid or reactive derivative thereof. These carboxylic compositions may be used in lubricating oil or fuel compositions or may be used to form carboxylic derivative compositions which are useful in lubricating oil and fuel compositions. Such useful carboxylic derivative compositions can be prepared by reacting at least one of the above-described carboxylic compositions with a reactant selected from the group consisting of (A) amines characterized by the presence within their structure of at least one H-N
Abstract:
The present invention relates to a process for reducing nitrogen oxides emissions from a diesel engine which comprises preparing an emulsion (80) of water in diesel fuel which contains a catalytically effective amount of catalyst composition (26) and a lubricity additive and supplying said emulsion to a diesel engine for combusting therein, whereby combustion of the emulsion leads to a reduction in the nitrogen oxides emissions from the diesel engine when compared with combustion of diesel fuel alone.
Abstract:
An additive for lubricant or fuel, comprising at least one member selected from substituted hydroxy aromatic ester derivatives represented by general formulae (I) and (II), (wherein R1 through R5 represent each an organic group having six or more carbon atoms; a, b, d, e, k and m represent each 1 to 3; c, f, g, i and j represent each 0 to 3; h represents 0 to 4, provided f+g=1 to 3 and h+i=1 to 6); a lubricant or fuel additive composition containing the same; and a lubricant or fuel composition containing the same. The additive is suitable as an ashless cleaning agent that is excellent in high-temperature stability and can substitute for metallic cleaning agents. The lubricant or fuel composition containing the same is suitable as an internal-combustion engine lubricant or fuel capable of coping with future severe exhaust gas regulation.
Abstract:
Mannich condensation products prepared by the condensation of a compound of formula (III), wherein R is hydrogen or lower alkyl having 1 to 6 carbon atoms; R1 is hydrogen, hydroxy, lower alkyl or lower alkoxy; R3 and R4 are independently hydrogen or lower alkyl; R5 is hydrogen, alkyl, phenyl, aralkyl, alkaryl, or an acyl group of formula (a), wherein R6 is alkyl, phenyl, aralkyl or alkaryl; and n is an integer from 5 to 100; with an aldehyde and a nitrogen base selected from ammonia, lower alkylamine, a polyamine and mixtures thereof. The Mannich condensation products and their fuel-soluble salts are useful as fuel additives for the prevention and control of engine deposits.
Abstract:
A fuel composition for two-cycle engines comprising a major amount of fuel boiling in the gasoline range and a minor amount of a lubricant composition comprising a base oil of lubricating viscosity and an additive formulation comprising (1) a molybdenum/sulfur complex of a basic nitrogen compound, (2) a carboxylic acid amide, and (3) a succinimide.
Abstract:
A lubricant-fuel mixture containing an amine salt and/or amide of a benzoic acid or thiobenzoic acid derivative, an amine salt of a phosphoric acid derivative, or certain quaternary ammonium hydroxides is effective in reducing the smoke emitted during operation of a two-cycle internal combustion engine.
