Additive to improve combustion in internal combustion engines and boilers |
(57) The present invention relates to additives for internal combustion engine and boiler
fuels containing water, to improve combustion, reduce emissions of carbon monoxide
(CO) and unburned hydrocarbons (HC), reduce formation of fumes, particles and carbonaceous
deposits and reduce fuel consumption, consisting of mixtures of a) aqueous solutions
of one or more aminoacids, b) one or more alcohols having 1 to 5 carbon atoms, and
optionally c) reaction products of acids and basic nitrogenated products and/or d)
methyl esters of fatty acids and/or e) solvents compatible with the fuel. The formulation
of the additives for gasoline and diesel engines can also include compounds for improving
the octane and cetane numbers, respectively.
