Chemical clean combustion promoter compositions for liquid fuels used in compression ignition engines and spark ignition engines

摘要

Catalytic clean-combustion-promoter compositions for use with finished gasoline or diesel fuels in compression ignition engines and spark ignition engines improve fuel efficiency and reduce air polluting emissions. The compositions utilize ketones as solvents, alcohols as cosolvents, nitroparaffin compounds as combustion supporters, and, to promote the chemical reactions, a catalytic medium is used. When the additive compositions are employed in microvolumetric concentrations ranging from 670 to 1,350 parts per million by volume of engine fuel, the chemical bonding of the carbon molecules with the oxygen molecules is increased during the combustion process, thus, producing a synergistic effect, which increases the combustion characteristic of the fuels to be burned and reduces the tendency of the fuel to create deposits, and therefore reduces the CO.sub.2 and NO.sub.X emissions, and increases the fuel economy. Engines operating with the present compositions added to the fuel do not require the use of fuels with a high cetane or octane number for maximum performance. The present chemical clean-combustion- promoter compounds meet the standards of the EPA "Clean Air Act" as amended in 1990 for emissions from liquid hydrocarbon fuels.
