What is a carburetor?

1 Answers

Carburetor is a device which combines gasoline and air creating a highly combustible mixture, regulates the ratio of air and fuel, and also controls the engine's speed.

How Carburetor Works: When the piston moves down the cylinder on the intake stroke it draws air from the cylinder and intake manifold. A vacuum is created that draws air from the carburetor. The airflow through the carburetor causes fuel to be drawn from the carburetor through the intake manifold past the intake valves and into the cylinder. The amount of fuel mixed into the air to obtain the required air to fuel ratio is controlled by the venturi or choke. When air flows through the venturi its speed increases and the pressure drops. This causes the fuel to be sucked into the air stream from a hole or jet.
