METHOD OF ELECTRICAL TREATMENT AND USE OF LOW-OCTANE FUEL IN INTERNAL COMBUSTION ENGINE AND FUEL PREPARATION SYSTEM FOR ITS EMBODIMENT Russian patent published in 2009 - IPC F02M27/00 F02B51/04 

FIELD: engines and pumps.

SUBSTANCE: invention relates to methods and systems of fuel preparation and can be used in oil and automotive industries and other industrial branches. Proposed invention aims at increasing efficiency of application of low-octane fuels and control over their physical and chemical properties. To this end, proposed method comprises suction of air from atmosphere, cleaning it in air filter, throttling, forming fuel-air mixture, adding high-octane component and feeding produced mix into engine cylinders. In compliance with this method, prior to forming fuel-air mixture, low-octane hydrocarbon fuel is fed into the field of centrifugal forces and subjected to chain reaction of cracking of fuel hydrocarbon molecules at normal conditions and feeding it through electric field with intensity of 2.12…7.54 kV/A, current strength of 1.48…3.35 A, pulse frequency of 0.46…1.0 kHz and voltage of 10…30 kV in fuel electric treatment unit. After electric treatment, amine fuel and/or xylidines, or mix thereof, or ethers, for example monomethyl ether and/or mix thereof are added as high-octane component. Obtained mix is fed into mixer-proportioner fuel properties are brought to required values. This method is implemented in the ICE fuel preparation system comprising electric preparation and quality control units, low-octane and high-octane components tanks, pipeline with shut-off and control valves and mixer-proportioner.

EFFECT: perfected method of fuel preparation.
