The use of tetrahydrobenzoxazines I ##STR00001##
where R.sup.1 is a hydrocarbyl radical and R.sup.2, R.sup.3, R.sup.4 and R.sup.5 are each independently hydrogen atoms, hydroxyl groups or hydrocarbyl radicals, and where R.sup.2 to R.sup.5 may also form a second and a third tetrahydrooxazine ring, with the proviso that at least one of the substituents has from 4 to 3000 carbon atoms and the remaining substituents, when they are hydrocarbyl radicals, each have from 1 to 20 carbon atoms, as stabilizers for stabilizing inanimate organic material, especially turbine fuels, against the action of light, oxygen and heat.

Provided is a gasoline product containing a combustion improver, and a method for preparing the gasoline product. The combustion improver is added to gasoline to reduce an octane number and thus an ignition point of the gasoline, so that the gasoline product can be used in a compression ignition internal combustion engine. The combustion improver-containing gasoline product is a low-octane number gasoline, and is capable of being ignited through compression by an internal combustion engine having a compression ratio in the range from 12 to 22.

The present technology is related to imide containing quaternary ammonium salts having a hydrocarbyl substituent of number average molecular weight less 300, and additive packages having such quaternary ammonium salts and improved stability.

New, highly effective substantially pure Mannich detergents for use in hydrocarbon fuels reduce engine deposits in spark and compression ignition internal combustion engines. The Mannich condensation reaction products are obtainable by reacting: (i) a polyamine having primary amino groups, (ii) a hydrocarbyl-substituted hydroxyaromatic compound, and (iii) an aldehyde, wherein the reaction is conducted at in a molar ratio of (i):(ii):(iii) of approximately 1:2:3. The Mannich detergent compounds may be dispersed in a liquid carrier to provide a fuel additive concentrate for hydrocarbon engine fuels which effectively control engine deposit formation in intake valves, port fuel injectors and combustion chambers.

Provided herein are biodiesel fuel mixtures having improved properties for reducing NOx emissions as well as total particular matter emissions, CO emissions, and total hydrocarbon emissions.

A fuel composition that provides a renewable biofuel energy source for reducing dependence on fossil fuels and improving air quality by reducing the amount of carbon monoxide released into the air during combustion. The fuel composition includes an energy crop comprising: a solid granular component being suspended in a liquid non-petroleum plant based fuel. The liquid fuel containing the granular component is efficacious in releasing copious quantities of vapor for burning. The vapor provides a more complete and efficient burn. The fuel composition further comprises an oxidizing agent for removing a plurality of electrons from the granular component during combustion, and/or an additive that imparts a change in the physical properties of the fuel composition.
