Abstract:
A fuel composition for internal combustion engines, and more particularly, a fuel composition for internal combustion engines containing less than about 0.5 gram of lead per gallon of fuel. The fuel provides acceptable valve seat protection in eingines designed to operate on leaded fuels. A further aspect of the invention is to reduce deposit formation within the cylinders.
Abstract:
Improved additives/detergents for lubricant and fuel compositions are obtained by condensing a hydroxyalkyl or hydroxyaryl compound with an amine compound. The condensates according to the present invention are produced by the acid catalyzed condensation of the amine reactant with the hydroxy reactant.
Abstract:
The present invention is related to the use of formulations of new random copolymers and terpolymers, synthesized by a method of semi continuous emulsion polymerization, and that function as flow improvers, lowering the pour point and reducing the viscosity of Mexicans crude oils, which have gravities within the range of 9 to 30° API.
Abstract:
This invention relates to a fuel additive whose composition in weight percentage is as follows: nitrogen monoxide 1˜76%, hydrogen peroxide 20˜83%, ethylene 3˜66%, acetone 1˜64%, dichlorodifluoromethane 1˜60%, benzene 1˜60%, carbon tetrachloride 1˜60%, petroleum ether 1˜60%, butanone 1˜60%, ethanol 1˜60%, methanol 1˜60%, ethyl ether 1˜60%, nitryl oil 1˜60%, isopropanol 1˜60%, dichloromethane 1˜60%, toluene 1˜60%, acetonitrile 1˜89%, n-butanol 1˜76%, 2-butanol 1˜60%, tert-butanol 1˜89%, cyclohexane 1˜76%, diethyl ether 1˜90% and nitromethane 1˜76%. Mix the above components well and dissolve them into a solution. The addition should be in the volume ratio of 1:700˜1:60000 when applied. The fuel additive using this invention can improve the combustion rate of the fuel, reduce the emission of air pollutants, cause no damage or side effect on any metal component of the engine, prolong the equipment life, accelerate the start of the engine, clear the accumulated carbon in the valves, spark plugs, cylinder, flywheel ring gear and in various engines.
Abstract:
Tropospheric volume elements enriched with vital elements and/or protective substances as well as procedures for their production and application. The term “vital elements” applies to all matter supporting the development of life within the earth's biosphere and the term “protective substances” means all those substances which contribute directly or indirectly to the prevention of harmful effects on the earth's biosphere and in particular on man. Tropospheric volume elements in the form of clouds which contain contaminants and which can escape from industrial facilities due to damage or malfunction are enriched with protective substances which prevent the organism from taking in radioactive elements and minimize the extent of the area affected by the clouds and possess additional warning and identification properties.
Abstract:
Disclosed is a leaded motor fuel additive composition which synergistically interacts with the alkyl lead additive to reduce both fuel intake system deposit formation and combustion chamber deposit formation, thereby reducing engine ORI and maintaining desired engine performance.
Abstract:
A fuel rendering composition, an alternative supplemental fuel and a universal fuel treatment. Halogenated hydrocarbon(s) and solvent(s), particularly terpenoid containing solvent(s), are combined to form a composition that when mixed with vegetable oil, crude or refined, renders that oil suitable for use in a diesel engine. Various hydrocarbons, solvents and related compounds are disclosed. Providing a metal-organic compound such as a cyclopentadienyl compound with a halogenated hydrocarbon and solvent at appropriate rates produces a universal fuel treatment.
