A device for reducing noxious emissions from carburetor engines of the internal combustion type, the body of which comprises at least one main passage designed for feeding a fuel-air mixture to the engine cylinders and has an emulsion passage. The main passage accommodates a throttle valve which divides it into an upstream throttle space and a downstream throttle space, as viewed in the direction of the fuel-air mixture flow. The emulsion passage communicates with the upstream throttle space substantially in the area where the throttle valve upper edge locates when the throttle valve is in the closed position and also communicates further, as viewed in the direction of the emulsion flow, via an adjustable throttle element with a chamber which communicates via an air passage with the upstream throttle space and via a passage with the downstream throttle space. The chamber accommodates a movable element adapted to move coaxially with the passage for the purpose of closing same. A sleeve is installed in the chamber in such a manner that a narrow annular passage is formed between the inner wall of the sleeve and the outer wall of the movable element. Said annular passage connects with the emulsion passage downstream of the adjustable throttling element with respect to the direction of the emulsion flow and separates the chamber space communicating with the downstream throttle space from the chamber space which communicates with the upstream throttle space.
