METHOD OF AND SYSTEM TO PREPARE AND DELIVER FUEL-WATER EMULSION INTO INTERNAL COMBUSTION ENGINES AND REMOVE OF NON-USED FUEL-WATER EMULSION FROM STANDARD FUEL SYSTEM Russian patent published in 2007 - IPC F02M25/22 

FIELD: mechanical engineering; internal combustion engines.

SUBSTANCE: proposed method to prepare and deliver fuel-water emulsion into internal combustion engine and remove non-used fuel-water emulsion from standard fuel system includes delivery of fuel, water, and liquid additions, their mixing to from homogeneous emulsion and delivery of said emulsion into standard fuel system. Two emulsifiers are used to emulsify components. First emulsifier operates for suction from standard fuel pump, and second one operates for delivery from the same pump. At suction stage flow of components is saturated with atmosphere air, and at delivery stage, air is forced out. Proposed system for preparation and delivery of fuel-water emulsion into internal combustion engine and removal of non-used fuel-water emulsion from standard fuel system contains fuel tank, reservoir with water, water filter, fuel filter, meters, standard fuel pump, fuel-feed pump and first emulsifier. System contains also second emulsifier and container with additions. First emulsifier operates for suction from standard fuel pump, and second emulsifier operates for delivery from the same pump. Fuel-feed pump provides evacuation of non-used fuel-water emulsion from standard fuel system after stopping of internal combustion engine and it feeds pure fuel into standard fuel system when switching on ignition.

EFFECT: possibility of preparation of fuel-water emulsion which can be used in engines without modification of standard fuel system.
