Carburettors are divided into bubbling and wick, currently not in use, membrane-needle and float, which make up the vast majority of all carburetors.
A bubbling carburetor is a gas tank in which, at some distance from the fuel surface, there is a blank board and two wide pipes - which supply air from the atmosphere and take the mixture into the engine. The air passed under the board above the surface of the fuel and, saturated with its v***rs, formed a combustible mixture. For all its primitiveness, this carburetor is the only one that provides a mixture with air of precisely the v***r fraction of the fuel. The throttle valve was on the engine separately. The bubbling carburetor made the engine very demanding on the fractional composition of the fuel, since its volatility had to occupy a very narrow temperature range, the whole structure was explosive, cumbersome, and difficult to regulate. The fuel-air mixture in the long path was partially condensed, this process often depended on the weather.
