Abstract:
The present invention relates to the use of a diesel fuel additive comprising a peroxide for reducing the fuel consumption in a diesel engine.
Abstract:
An additive composition for use in a diesel fuel formulation, comprising a cetane improver which is present as a guest molecule in an inclusion complex with a modified cyclodextrin of formula (I): wherein n is an integer from 6 to 20, and R 1 , R 2 and R 3 are each independently selected from hydrogen, optionally substituted alkyl, optionally substituted aryl and carbonyl, provided that R 1 , R 2 and R 3 are not all hydrogen. Also provided is a diesel fuel formulation comprising the additive composition, and the use of a modified cyclodextrin (I) as a vehicle for a cetane improver in an additive composition or diesel fuel formulation.
Abstract:
The invention provides fuel mixtures containing fuel oil, glycerol, glycerol impurities and non-ionic surfactants. The mixtures remain homogeneous longer and are more chemically stable than previous mixtures. Upon combustion, the mixtures generate reduced SOx, NOx and particulate matter emissions compared to residual fuels and offer improved engine performance over previous mixtures.
Abstract:
A diesel fuel composition is disclosed, as well as a method for reducing NOx emissions from a diesel engine at minimum fuel consumption wherein the diesel engine operates in a low temperature combustion mode, comprising the step of adding to the diesel engine at least one diesel fuel or blending component for a diesel fuel having a combination of a low T50 in the range of from 19O0C to 28O0C, a high cetane number in the range of from 31 to 60, and an effective emissions reducing amount of a nitrogen-free cetane improver.
Abstract:
The use of at least one cetane improver and at least one fatty acid mono-alkyl ester in which the fatty acid has less than 16 carbon atoms, to reduce the emissions of both particulate matter having a particle size of up to 32 nm and nitrogen oxides, on combustion of a fuel composition in a compression ignition engine; a method of reducing the emissions of both particulate matter having a particle size of up to 32 nm and nitrogen oxides on combustion in a compression ignition engine of a fuel composition comprising at least one fatty acid mono-alkyl ester by providing sufficient of at least one cetane improver in the fuel composition to provide a pre-determined cetane value for the fuel composition and providing that at least 5 percent by volume of the fatty acid mono-alkyl esters in the fuel composition are mono-alkyl esters of fatty acids in which the fatty acids have less than 16 carbon atoms; and a fuel composition comprising at least one fatty acid mono-alkyl ester and at least one cetane improver in which that at least 5 percent by volume of the fatty acid mono-alkyl esters in the fuel composition are mono-alkyl esters of fatty acids in which the fatty acids have less than 16 carbon atoms.
Abstract:
The present invention relates generally to a composition and method for decreasing the emissions from combustion of fuel that contains biodiesel, where the composition contains at least one ignition accelerator and at least one plant extract or synthetic component similar to a portion of a plant extract. The ignition accelerator is preferably a peroxide, for example, di-tert-butyl peroxide. The composition may optionally contain meadowfoam oil or jojoba oil. The composition may also enhance the lubricity of the fuel that contains biodiesel.
Abstract:
[PROBLEMS] To provide a modifier for a biodiesel fuel (BDF) such as a methylesterificated fuel. [MEANS FOR SOLVING PROBLEMS] A modifier for a biodiesel fuel, which is prepared by a method comprising subjecting a vegetable oil such as a sun flower oil, a rapeseed oil, or a soybean oil to an ozone treatment. The addition of the above modifier for a biodiesel fuel lowers the pour point of the biodiesel fuel, and thus the above modifier allows the use of a biodiesel fuel also in a cold district. Further, the addition of the above modifier for a biodiesel fuel to a biodiesel fuel can improve the engine performance of a diesel engine, in particular, the torque and horsepower during a low engine speed.
