How a Carburetor Works | Air–Fuel Mixing Explained

This visual explains the basic working principle of a carburetor, showing how air intake, fuel flow, and the venturi effect combine to create the air–fuel mixture delivered to the engine cylinders. While carburetors were simple and reliable for their time, they lack the precision of modern fuel injection systems, often leading to wasted fuel and reduced emissions control. Understanding this system highlights why fuel injection has become the standard for efficiency, performance, and cleaner operation in today’s engines.
