METHOD OF AND DEVICE FOR DELIVERY OF FUEL-AIR MIXTURE TO INTERNAL COMBUSTION ENGINE Russian patent published in 1997 - IPC

FIELD: mechanical engineering; fuel systems of carburetor engines. SUBSTANCE: method of fuel air-mixture delivery into internal combustion engine comes to the following: fuel-air mixture getting from emulsion well is additionally heated, prior to atomizing by additional air stream, to temperature higher than boiling point but lower than fuel-air mixture self-ignition point. Heating is done by heating additional air stream which, in its turn, is heated by engine exhaust gases. Device has additional air source, pneumatic line with series sections one of which encloses exhaust gas muffler intake pipe and other is provided with cooling gasket with intake and outlet branch pipes. Valve-thermostat is installed in one of branch pipes. Fuel-air mixture atomizer is made of heat conducting material being enclosed in tapering housing connected with pneumatic line. Additional diffuser is arranged concentrically with tapering housing so that end of housing is located in plane of minimum passage area of additional diffuser. EFFECT: improved delivery of fuel. 5 cl, 1 dwg
