摘要:
A lubricant composition includes a mineral lubricanting lubricant composition and a friction modifying amount of a reaction product of an amine and maleic anhydride represented by the formula: ##STR1## in which X and X' are either: ##STR2## in which R and R' can be any hydrocarbon radicals and the total number of carbon atoms in R plus R' varies from about 6 to about 30, and wherein the nitrogen is bound to a secondary carbon atom, or wherein R is a hydrogen atom and R' is a branched hydrocarbon radical having from about 6 to 30 carbon atoms, or ##STR3## in which Y varies from 2 to 6, and in which R" is a hydrocarbon radical having from about 6 to 30 carbon atoms, and R"' is hydrogen or a methyl radical. The lubricant composition finds use in various internal combustion engines including slow and medium speed diesel engines and as a lubricant in the upper cylinder of a slow speed marine diesel engine.

A diesel fuel composition which is comprised of:(a) a major portion of a low-sulfur content diesel fuel; and(b) a minor amount, as an anti-wear lubricity additive, of a dithiophosphoric diester-dialcohol.
摘要:
The present invention provides a novel class of compounds, useful as gasoline detergent additives, comprising asymmetrical ureas of either a hydrocarbyloxypolyether amine alone, or a hydrocarbyloxypolyether amine and a tertiary aminoalkyl primary amine. The present invention also provides a motor fuel composition containing the novel asymmetrical ureas and further provides a method of synthesizing the asymmetrical ureas of the present invention.
摘要:
A method of stabilizing a diesel fuel formulation by substantially minimizing the oxidation thereof is disclosed. In particular, at least one amine containing copolymer is incorporated into the diesel fuel formulation in an amount sufficient to improve the storage stability and, also, substantially minimize the oxidation thereof. The method of this invention is particularly well suited for substantially minimizing the high temperature oxidation of diesel fuels.
