The present invention relates to fuel additives, fuel compositions and methods of manufacture in which the additives are provided to impart desired properties to fuels. These properties include, without limitation, reduction of nitrogen oxide and particulate emissions from the exhaust stream of internal combustion engines using the fuels. Preferred embodiments of an additive form of the composition include a nitrogen-containing compound selected from the group consisting of urea, cyanuric acid, triazine, ammonia and mixtures thereof, a carrier blend comprising an alkoxylated alcohol, a polyalkylene glycol ester and an alkanolamide and water. The additive may be provided in a concentrate form by addition of a solvent or may be provided as a final form fuel composition. A method of additive manufacture and is disclosed.

Fuel additive, additive-containing fuel compositions and method of manufacture

A stable, substantially clear and homogeneous fuel composition contains an additive comprising a nitrogen donor and carrier, the nitrogen donor being present in an amount sufficient to reduce the NOemissions of the fuel when subject to combustion and the carrier being selected to render the nitrogen donor soluble and to give the additive a molecular weight compatible with the energy properties of the fuel.

Fuel combustion

A method is provided for reducing the vapour pressure (RVP) of a gasoline/alcohol mixture which comprises adding a surfactant composition comprising an alkanolamide, an alkoxylated alcohol and an alkoxylated fatty acid to a gasoline/alcohol mixture.

Fuel composition

A fuel composition for a combustion engine that is treated with a hybrid molecule that is balanced into a polymer by ethoxylation, the result being a commercially viable fuel that is delivered to the point of combustion in the best possible condition with least resistance.
