CARBURETOR FOR INTERNAL COMBUSTION ENGINE Russian patent published in 1997 - IPC

FIELD: mechanical engineering; internal combustion engines with devices for homogenizing fuel-air mixture. SUBSTANCE: carburetor of internal combustion engine has body with through channel, smaller and larger venturis and homogenizer installed in tandem in channel in direction of air flow. Homogenizer is made in form of rotor installed on axle and placed in larger venturi at smaller venturi outlet. Axle of homogenizer is located eccentrically relative to axis of main through channel and is fastened to wall of smaller venturi. Diameter of homogenizer is equal to 0.3-55 of diameter of neck of larger venturi. According to one design version, disk rotor can be used, axis of rotor rotation being parallel with axis of larger venturi. Drum rotor can also be used with ratio of rotor diameter to length equal to 1.7-2.2 and axis of rotation of rotor arranged square to axis of larger venturi. EFFECT: cut down fuel consumption. 3 cl, 5 dwg
