The carburetor has been losing relevance to fuel injection systems, as these are less polluting and more efficient. It is still valued for its robustness and simplicity.
In this blog article we explain what a carburetor is and why it should keep it in good condition. Continue reading the article!
What is a carburetor?
The carburetor is responsible for mixing air and gasoline before the explosion occurred in the engine block.
By which components is a carburetor constituted?
- Floating Chamber.
- Float;
- Choke valve.
- Throttle valve;
- Main injector;
- Injection syringe;
- Piston valve screw;
- Main entrance.
The carburetor works for several phases and by various movements. But let’s go in parts.
How does the carburetor work?
- The operating combustion engine pulls the air in the intake chamber into the carburetor, more specifically in the mixing chamber.
- The fuel is sucked into this mixing chamber where they are separated by a butterfly valve. This valve regulates the fuel flow and the air that is housed there for a short time.
- This butterfly valve lets the mixture between air and gasoline happen when the driver presses the accelerator;
- When the driver presses the accelerator, the butterfly valve opens allowing the mixture to enter In the carburetor.
- Then, this mixture is then carried into the cylinder for combustion.
What are the different types of carburetor?
- Vertical airflow carburetor;
- Horizontal airflow carburetor.
In the different types of airflow there are 3 types of mixing chambers:
- Simple type mixing chamber;
- Double mixing chamber;
- Mixing chamber register.
In each type of mixing chamber there are two types of airflow regulator:
- Butterfly valve;
- Guillotine.
What’s the carburetor for?
The carburetor serves to regulate the mixture between fuel and air that enters the engine. The carburetor is activated by the accelerator, that is, if the accelerator is pressed, the greater the air flow and fuel entering the engine and, consequently, the engine speed will be higher.
What are the most common problems in the carburetor?
- Air leak in the mixing adjustment screws;
- Dirty carburetor with fuel debris;
- Corrosion inside the carburetor;
- Seal in poor condition;
- Clogged carburetor.
How to clean the clogged carburetor?
- Clean the air filter;
- Disassemble the carburetor.
- Clean each part of the carburetor with a specific cleaning liquid.
- Use an air compressor to remove accumulated water and debris;
- Dry the components using a microfiber cloth;
- Reassemble all parts and put in place, always checking all fittings and functions.
- Start the engine and leave it running for 5 minutes;
- Drive the car for 20 minutes to confirm that the process was made correctly. Check the engine response as well.
Carburetor VS Electronic injection
Carburettor
The carburetor is a simple system that mixes air and fuel . It has the advantage of a being an equipment easily disassembled for any cleaning, repair or replacement. On the other hand, this system cannot be easily operated in cold environments as it has difficulty sending fuel to engine.
Electronic injection
Electronic injection systems are present in the most modern cars and has as main objectives: to make fuel consumption more efficient and reduce polluting gases emissions.
In addition, electronic injection easily adapts to all atmospheric conditions. On the other hand, this electronic system is vulnerable to errors and failures that cannot be circumvented by the user.
What is the necessary maintenance of the carburetor?
To ensure a good condition of the carburetor is essential:
- Make regular cleanings to prevent debris accumulation
- Synchronize the valves with the carburetor : KROFtools advises you to synchronize in a specialty workshop with a manometer kit.
