ABSTRACT:
The incorporation of these catalytic clean combustion promoters compositions to liquid fuels for internal combustion engines, improve their combustion properties; thus, reducing their air polluting emissions as nitrogen oxides (NO.sub.x), carbon monoxide (CO), and unburned hydrocarbons (HC). Also, these fuel activators reduce smoke and particulate matter exhaust emissions. Moreover, the addition of these fuel activators, reduce the corrosion properties of fuels, clean the whole fuel systems of gums and varnishes, clean and prevent carbon deposits on injectors, valves and on the combustion chamber parts.
The composition of these catalytic clean combustion promoters additives includes aromatic and aliphatic hydrocarbon solvents with and without oxygenated functional groups, aromatic amines, a catalytic agent in chemical reactions, nitroparaffin solvents, aliphatic ether as an octaine assistant, and/or Kerosene as a cetane assistant.
These chemical compositions can be incorporated to liquid fuels derivated from petroleum oils in micro-volumetric concentrations ranging from 400 to 2,500 parts per million (ppm.) by volume of engine fuel.
