FIELD: mechanical engineering; internal combustion engines.
SUBSTANCE: proposed device contains primary channel for air, controllable throttle, secondary channel for air, jet with adjustable hole for delivery into primary air channel, narrowing needle installed for movement in direction towards primary air channel and installed in bell, needle position control mechanism and narrowing needle drive. Device is furnished additionally with evaporating unit with holes provided with great number of channels for air passing through unit which divide longitudinal part of primary air channel between point of fuel intake and outlet. Device is such that fuel, air passing along secondary air channel and air passing along primary air channel pass along channels for mixing fuel and air. Control mechanism contains cam plate installed on shaft on which throttle is installed and provided with cam surface with drive for narrowing needle thrusting against cam plate.
EFFECT: improved mixing of fuel and air.
