A carburetor is a device used in internal combustion engines to mix air and fuel in the correct ratio for combustion. It utilizes Bernoulli's principle to create a vacuum that draws in air and fuel into the engine.
Bernoulli's principle states that as the speed of a fluid increases, its pressure decreases. In a carburetor, air flows through a narrow passage called a venturi, which causes the air to speed up. This decrease in pressure creates a vacuum that draws fuel from the carburetor's fuel bowl into the air stream, where it mixes with the air before entering the engine's combustion chamber.
By using Bernoulli's principle, a carburetor is able to precisely control the air-fuel mixture entering the engine, ensuring optimal combustion and engine performance.

Bernoulli's Principle
Bernoulli's principle states that as the velocity of a fluid increases, its pressure decreases. This principle is fundamental to understanding carburetor operation.
Carburetor
A carburetor is a device used in gasoline engines to mix air and fuel in the correct proportions for combustion. It utilizes the Venturi effect, which is a consequence of Bernoulli's principle.
Operation of a Carburetor
1. Air Intake: Air is drawn into the carburetor through a venturi, a narrow section in the intake passage.
2. Venturi Effect: As the air flows through the venturi, its velocity increases due to the constriction. According to Bernoulli's principle, this increase in velocity causes a drop in air pressure.
3. Fuel Injection: Fuel is injected into the venturi at a point where the air pressure is lowest. The reduced pressure draws fuel out of the fuel chamber and into the air stream.
4. Mixing: The low pressure in the venturi effectively sucks fuel droplets into the air stream, creating a fine mixture of air and fuel.
5. Air-Fuel Mixture: The air-fuel mixture then flows into the engine's intake manifold, where it is distributed to the individual cylinders for combustion.
Role of Bernoulli's Principle
Bernoulli's principle plays a crucial role in the carburetor by:
- Creating a low-pressure area in the venturi, which helps draw fuel out of the fuel chamber.
- Maintaining a constant fuel-to-air ratio by adjusting the amount of fuel injected into the venturi based on the air pressure.
- Ensuring proper mixing of air and fuel, which is essential for efficient combustion.
In summary, a carburetor uses Bernoulli's principle to create a low-pressure area that draws fuel into the air stream, resulting in a well-mixed air-fuel mixture for combustion in gasoline engines.
