METHOD AND DEVICE FOR PREPARING FUEL-AIR MIXTURE IN INTERNAL COMBUSTION ENGINE Russian patent published in 1995 - IPC

FIELD: engine engineering. SUBSTANCE: device has the mixing chamber of a carburetor, plate 2 with the space of mixer 3, blower 4 with sucking space 5 and delivery space 6, space 7 for treating fuel- air mixture, opening (passage) for supplying exhaust gases (heater) 8 made up as a pipe line in treating space 7, and passageway 9 of the circulator used to combine al of these members (3,5,6,7) and to define closed loop. To increase the area of heat contact, heater 8 is constructed as a coil pipe or provided with additional plates. A portion of the main flow of the fuel-air mixture is fed from the space of mixer 3 to blower 4 and then to the treating space 7 (heating and evaporation). Treated and heated fuel-air mixture in the form of vapor- air enter the space of mixer 3 wherein the mixture is mixed with the main flow of the fuel-air mixture to form a highly homogeneous mixture. EFFECT: simplified method and device. 5 cl, 5 dwg
