Mechanical Features and Designs

A carburetor is a tube-like device that connects to an internal combustion engine—namely a gasoline engine—and controls the intake of air into the engine. Its objective is to mix the exact amount of gasoline with air so the engine can run effectively. For example, if there is an insufficient amount of fuel mixed with air, the engine "runs lean." On the contrary, if there is a surplus of fuel mixed with air, the engine "runs rich."[1]

The carburetor works by having an adjustable plate called a throttle plate positioned across the tube, controlling the airflow into the tube by allowing only the necessary amount. In the tube, there is a narrowing called the venturi. This narrowing essentially creates a vacuum. Inside the narrowing, a hole called a jet lets the vacuum draw in the fuel.[2]

Most old vehicles were built with carburetors but it has now become standard that all new vehicles are universally built with fuel injection systems. A carburetor is also referred to as a “carb.”[3]
