carburetor

a device that mixes air and fuel for internal combustion engines

A carburetor is a part of an engine that mixes air and fuel in the right proportions before it enters the engine. It helps the engine get the right amount of fuel for different driving conditions. When the driver presses the gas pedal, the carburetor adjusts the amount of air and fuel to allow the engine to accelerate or slow down. The carburetor plays an important role in ensuring the engine runs smoothly, especially in older vehicles. Many modern cars use fuel injectors instead, which perform a similar function more precisely.
