7 Types of Carburetors in Cars and How They Work
The carburetor is a car component that functions as a regulator of the mixture of air and fuel in the engine cylinder. Knowing how it works and the types of carburetors is very beneficial for you, as you can better understand the power generation process for the car to move. Here are the types of carburetors in detail along with how they work.
Types of Carburetors
There are several types of carburetors that you need to know. Here are the complete types.
1. Down Draft Carburetor
The first type is the down draft carburetor. To move air, this type of carburetor uses a vertical flow from top to bottom. This type of carburetor is usually used in large capacity cars.
2. Up Draft Carburetor
The second type is the up draft carburetor. This type can be said to be the opposite of the down draft carburetor. To move air, the up draft carburetor uses a vertical flow from bottom to top towards the intake part.
3. Side Draft Carburetor
The third type is the side draft carburetor. As the name suggests, this carburetor uses the side part as the entry point for fuel or air. Later, the air and fuel will be mixed and distributed to the cylinder for the engine combustion process.
4. Fixed Venturi Carburetor
The fourth type is the fixed venturi carburetor. This type can be found in newer model cars due to its simple design.
5. Variable Venturi Carburetor
The next type is the variable venturi carburetor. This type has a slightly more complex shape compared to the fixed venturi type. This type of carburetor utilizes the surface area to regulate the amount of air that will enter. The mechanism of this carburetor is quite unique, as the valve opening is always aligned even at medium or low speeds.
6. Air Valve Venturi Carburetor
The next type is the air valve venturi carburetor. As the name suggests, this type of carburetor utilizes air as the main regulator when the air valve opens. The surface of this air valve carburetor is similar to that of a downdraft double barrel carburetor.

7. Barrel Carburetor
The barrel carburetor uses a barrel as its main support. The barrel type carburetor is divided into two, namely single barrel and double barrel. Here is a more detailed explanation.
Single Barrel Carburetor
In its working mechanism, the single barrel carburetor only utilizes one barrel as support. Therefore, the performance of this carburetor is somewhat slow due to the heavy workload it bears.
Double Barrel Carburetor
As the name suggests, this type of carburetor utilizes two barrels and venturis with a relatively small diameter to perform its function. The use of two barrels affects the performance of the carburetor, making it faster compared to the single barrel carburetor.
Thus, here are some types of carburetors that you need to know. To ensure this component functions optimally, you can perform regular checks and maintenance on the carburetor. You can do the maintenance yourself.
If you intend to perform maintenance yourself, you can open the engine air filter using a size 12 and 10 wrench. Then remove the carburetor drain bolt using a size 14 wrench.
Next, readjust the carburetor and don't forget to clean the carburetor with carburetor cleaner. The next step is to check the performance of the carburetor by starting the engine in idle condition to determine if it is running smoothly or not.
