Understanding the Carburetor: A Comprehensive Guide

“My old truck’s been sluggish lately, probably a clogged carburetor again!” This common complaint from Mr. Ba, the owner of a well-worn truck in Long Bien, Hanoi, reminds me of my early days exploring the fascinating world of automobiles. The carburetor, seemingly complex, actually has a rather interesting structure and operating principle. Today, let’s delve into the details of this “heart” of the gasoline engine with XE TẢI HÀ NỘI!

Carburetor Structure

1. Introduction to the Carburetor

The carburetor is a crucial mechanical device responsible for mixing air and fuel in a specific ratio before it enters the combustion chamber of a gasoline engine. Thanks to the carburetor, the engine can operate smoothly and efficiently.

2. Detailed Structure

Although there are various types of carburetors, they generally consist of the following main components:

• Intake Manifold: The primary air passage where air enters the carburetor.
• Throttle Body: Includes the throttle valve and fuel injector, responsible for regulating the amount of air-fuel mixture entering the combustion chamber.
• Float Chamber: Contains the float and float needle, maintaining a consistent fuel level within the chamber.
• Venturi: A narrow section in the intake manifold that accelerates airflow and creates low pressure to draw fuel.
• Jets: Small precisely sized holes that control the amount of fuel sprayed.

3. Operating Principle

When the engine runs, the piston moves downward, creating a vacuum in the combustion chamber. This vacuum draws air through the intake manifold into the carburetor. As air passes through the venturi, its speed increases, creating a pressure lower than that in the float chamber. This pressure difference draws fuel from the float chamber through the jets, mixing it with the air to form the air-fuel mixture.

The air-fuel ratio is controlled by the throttle valve and fuel injector. When you press the accelerator, the throttle valve opens, allowing more air-fuel mixture into the combustion chamber, enabling the engine to generate more power.

Price List

Currently, various carburetors are available on the market with diverse prices, depending on the brand, type, and condition. Below is a reference price list for some common types:
