Abstract:
The present disclosure provides compositions and methods for reducing deposit formation in engines combusting a fuel containing ethanol and a corrosion inhibitor. The present disclosure also provides compositions and methods for reducing deposit formation in engines combusting a fuel containing ethanol, a corrosion inhibitor, and a dispersant.
Abstract:
The present invention relates to the use of detergent additives for reducing or preventing the formation of deposits in the injection systems of direct-injection diesel engines and in particular in common rail injection systems.
Abstract:
The invention relates to the field of masking mineral oil odor and the fragrancing of mineral oils. In this connection, the invention relates to a selection of particularly suitable odoriferous substances for masking a mineral oil odor and for fragrancing mineral oils. The invention furthermore relates to additives and to corresponding fragranced mineral oils themselves, in particular motor fuels and heating or lubricant oils.
Abstract:
An adjustable fuel power booster component composition having three components: (A) an ignition accelerator which is preferably normal propyl nitrate and/or diterbutyl peroxide; (B) propylene glycol monoalkyl ether and/or butylene glycol monoalkyl ether; and (C) methyl carbonate and/or ethyl carbonate and/or propyl carbonate and/or butyl carbonate, which may be used mixed in any proportion with methylal (dimethoxymethane) or ethylal (diethoxymethane). The adjustable fuel power booster component composition of the present invention can be used by itself or in mixture with gasoline, diesel or burning oils in combustion engines without the need for modification thereof. The adjustable fuel power booster component composition enables low energy content alcohol based fuels to substitute conventional fuels, such as gasoline or diesel, in conventional non-modified internal combustion engines, thereby generating lower amounts of toxic gas emission all the while proving more power.
Abstract:
Compositions containing phenolic antioxidant solutions are provided. The invention further provides methods of making and using such compositions as well as compositions that contain both biodiesel and at least one antioxidant concentrate solutions and blended fuel compositions containing biodiesel blended with other fuels.
Abstract:
The present invention provides a diesel composition having an excellent ignitability despite inclusion of ethanol therein. The diesel composition includes a diesel base material, ethanol in a range from 5 to 30% by weight based on the total amount of the diesel base material, and ethyl nitrite or ethyl nitrate in a range from 0.5 to 7% by weight based on the total amount of the diesel base material. The content of the ethyl nitrite or ethyl nitrate falls within a range of 50% by weight or less of the content of the ethanol, and the ethyl nitrite or ethyl nitrate is derived from ethanol as a raw material.
Abstract:
The present invention relates to a fuel conditioning process for internal combustion engines of motor vehicles. According to the present invention, on board a motor vehicle at a temperature of from 20° C. to 150° C. and at atmospheric pressure, nitrous gases essentially including nitrogen monoxide, nitrogen dioxide, or dinitrogen monoxide, or gaseous mixtures thereof are passed through the liquid fuel of the motor vehicle, nitro compounds being formed in the fuel as a result of the passing through of the nitrous gases through the fuel.
Abstract:
Diesel fuels with additives to increase cetane number include chemistries to increase surface absorption and improve lubricity in high cetane number fuels. Fuels and additives also contain thermal stability improvers.
Abstract:
Fuel for motor vehicles comprising an emulsion between water and a liquid hydrocarbon, and an anti-cavitation additive comprising a copolymer including 20-80% in moles, preferably 35-70% in moles, of units containing at least one carboxylic group and 80-20% in moles, preferably 65-30% in moles, of units deriving from at least one monomer having an ethylene unsaturation, and wherein at least 20% in moles of the carboxylic groups, preferably 30-90% in moles, is in the form of at least one derivative selected from carboxylate salt, ester, amide and imide.
Abstract:
A method for marking a liquid petroleum hydrocarbon. The method comprises adding to the liquid petroleum hydrocarbon at least one substituted anthraquinone dye having formula (I) wherein R1 and R2 independently are hydrogen, hydroxy, OR11, amino or NR11R12; R3 and R5 independently are alkyl, aryl, aralkyl, heteroalkyl or heterocyclic; R4 and R6 independently are hydrogen or alkyl; R7, R8, R9 and R10 independently are cyano, nitro or hydrogen, provided that at least two of R7, R8, R9 and R10 are cyano or nitro; R11 is alkyl, aryl, aralkyl, heteroalkyl, heterocyclic or alkanoyl; R12 is hydrogen or alkyl; and wherein the substituted anthraquinone dye(s) has an absorption maximum in the range from 690 nm to 1000 nm.
