A fuel additive composition essentially comprising nitrogen-containing dispersants, carrier oils, the above tertiary hydrocarbyl amines and optionally further friction modifiers. A fuel composition comprising a major amount of gasoline and a minor amount of the above fuel additive composition.
Abstract:
The invention provides a fuel composition comprising: a base fuel; a copolymer of ethylene and an olefinically unsaturated compound; and a cloud point depressant additive which comprises a nitrogen-containing compound and a polysulphone; wherein the cloud point of the fuel composition is lower than it would have been in the absence of the cloud point depressant additive; and wherein the CFPP of the composition is no higher than it would have been in the absence of the cloud point depressant additive.
Abstract:
There is described a method of combating antagonism between a first component, namely a cold flow improver, and a second component, namely a drag reducing agent, in a liquid fuel composition, the antagonism being a reduction in the low temperature benefit achieved by the first component, by including in the fuel composition a third component, namely a compound selected from: a copolymer of one or more alkenes and sulphur dioxide; a copolymer of one or more alkenes with acrylonitrile; a copolymer of alkyl vinyl monomers and cationic monomers; a conductivity improver; and mixtures thereof. Related compositions and uses are also described.
