A carburetor is a device used in older petrol internal combustion engines to control and mix air and fuel entering the engine. It relies on the Venturi effect or Bernoulli's principle to create a vacuum that draws fuel into the airstream. Key components include the float chamber, throttle valve, choke valve, and jet needles, which work together to adjust the air-fuel mixture. However, since the late 1980s, carburetors have been largely replaced by fuel injection systems in cars and trucks due to their greater efficiency, precision, and reduced pollution. Today, carburetors are mostly found in small engines like those in lawnmowers, generators, and some motorcycles, as well as in piston-engine-driven aircraft[5).
