Carburetor

A carburetor is a device that mixes air and fuel in the correct ratio for combustion in a gasoline internal combustion engine, delivering this mixture to the engine cylinders.

Here’s a more detailed explanation:

Function:

The primary function of a carburetor is to prepare the air-fuel mixture that is needed for combustion in an engine.

How it works:

Air enters the carburetor, often through an air cleaner.
Within the carburetor, fuel is added to the air stream.
The mixture then passes into the intake manifold, where it’s delivered to the engine cylinders.

The mixture is then ignited, which powers the vehicle.

Components:

Venturi: A narrowed section in the carburetor that increases air velocity, creating a low-pressure area that draws fuel into the airstream.

Jets: Small orifices that control the flow of fuel into the air stream.

Float Chamber: A reservoir that holds a supply of fuel.

Choke: A valve that restricts airflow during cold starts, enriching the fuel mixture.

Throttle: A valve that controls the amount of air and fuel entering the engine.

Historical Context:
Carburetors were commonly used in older gasoline-powered vehicles before the widespread adoption of fuel injection systems.

Modern Use:
While fuel injection has become more common in newer vehicles, carburetors are still used in some smaller engines, such as those found in lawnmowers and
chainsaws.
