The Carburetor: Structure, Working Principles, and FAQs

I vividly remember my childhood days, tagging along with my grandfather to the auto repair shop at the end of Ly Nam De Street. Amidst the clang of hammers and the pungent smell of oil, my grandfather, a skilled mechanic, would meticulously repair his old truck. I was fascinated by how he carefully adjusted each screw on the “heart” of the vehicle – the carburetor. Nowadays, electronic fuel injection systems are common, but for many, the carburetor remains a nostalgic part of “legendary” trucks.

What is a Carburetor?

A carburetor is a device that blends air and fuel (gasoline) in a specific ratio before delivering the mixture to the engine’s combustion chamber. It operates based on the principle of pressure difference, drawing fuel from the tank, mixing it with air, and then sending it to the engine cylinders.

Structure and Working Principles

Structure

A carburetor has a complex structure, consisting of many small parts working in harmony. Some of the main components include:

• Intake Manifold: Where air enters the carburetor.
• Mixing Chamber: Where fuel and air are mixed.
• Jets: Control the amount of fuel entering the combustion chamber.
• Throttle Valve: Regulates the amount of air-fuel mixture entering the engine.
• Float Valve: Maintains a consistent fuel level in the float chamber.

Working Principles

When the engine runs, the downward movement of the piston creates a pressure difference, drawing air into the intake manifold. Simultaneously, fuel is drawn from the tank to the float chamber due to pressure difference. In the mixing chamber, fuel is sprayed from the jets and mixed with air at a specific ratio. The amount of air-fuel mixture entering the engine is controlled by the throttle valve.

Advantages and Disadvantages of Carburetors

Advantages

• Simple Structure: Easy to repair and maintain.
• Low Cost: Replacement and repair costs are lower compared to electronic fuel injection systems.

Disadvantages

• Poor Fuel Mixing: Leads to low engine efficiency, high fuel consumption, and increased emissions.
• Difficult Cold Starts: Due to the difficulty of fuel vaporization at low temperatures.
