Carburetors

The carburetor is a mechanism that combines both air and fuel for internal combustion engines in a specific ratio for combustion. To carburate is to mix air and fuel for the combustion process.

Carburetor principles

The carburetor operates on the notion that, the faster the air moves, the lower its static pressure and high the pressure is. The accelerator linkage does not manage the flow of the fuel, but it does have carburetor machinery that calculates the amount of air entering the engine. The speed of flow and pressure tells you the amount of fuel being sucked into the airstream.

Carburetor function

The combustion process begins by mixing fuel with air in the precise ratio for working conditions and demand. The carburetor utilizes a fuel and air combination for combustion. The carburetor operates because of the pressure differential, it sucks air in and travels via the venturi causing an increase in speed and the pressure drops which draw fuel from the float bowl.

Common problems with a faulty carburetor

A defective carburetor can lead to rough idling, failure to start, or a decline in engine performance.
