Although carburetor technology in automobiles reached a very high degree of sophistication and precision, from the mid-1980s it lost out on cost and flexibility to fuel injection. Simple forms of carburetor remain in widespread use in small engines such as lawn mowers and more sophisticated forms are still used in small motorcycles.

A 'power valve', which is a spring-loaded valve in the carburetor that is held shut by engine vacuum, is often used to do so. As the airflow through the carburetor increases the reduced manifold vacuum pulls the power valve open, allowing more fuel into the main metering circuit.
Petrol engines often use simple fuel systems consisting of a float-type carburetor with a fuel tank located above it (so that the fuel is delivered by gravity, avoiding the need for a fuel pump). Sometimes, the fuel tank is located below the carburetor and fuel is delivered using engine vacuum or crankcase pressure pulsations.
Most choke valves in engines are butterfly valves mounted upstream of the carburetor jet to produce a higher partial vacuum, which increases the fuel draw. [ 1 ] In heavy industrial or fluid engineering contexts, including oil and gas production, a choke valve or choke is a particular design of valve with a solid cylinder placed inside another ...
Of the three types of carburetors used on large, high-performance aircraft engines manufactured in the United States during World War II, the Bendix-Stromberg pressure carburetor was the one most commonly found. The other two carburetor types were manufactured by Chandler Groves (later Holley Carburetor Company) and Chandler Evans Control ...
An updraft carburetor is a type of carburetor in which the air flows upward within the device. [1] Other types are downdraft and sidedraft. [2] An updraft carburetor was the first type in common use. [3] In it air flows upward into the venturi to mix with the fuel. [2] An updraft carburetor may need a drip collector. [4]
