Carburetor VS Fi System :
Difference Between Carburetor and Fuel Injection:
Since the invention of the internal combustion engine, automobile engineers have strived to find effective ways to deliver air and fuel to the combustion engine. The device which controls the ratio of air-fuel mixture entering the engine is known as a carburetor, a fuel injection system also does the same. Then what is the difference between carburetor and fuel injection?
In simple terms, a carburetor helps the air-fuel mixture to enter the combustion chamber. All this is done through mechanical parts. The fuel injection system also helps the combustion chamber to get air-fuel mixture, but with the aid of electronics and sensors, and not through mechanical parts.
Carburetor Engine: How Does It Work
The only or primary job of a carburetor is to mix fuel and air in a certain ratio and feed it to the combustion chamber. The device intercepts the flow of air to the combustion chamber, mixes fuel and delivers it to the engine. When the throttle of the bike is squeezed, the airflow to the carburetor increases causing suction of air and the delivery of fuel increases accordingly resulting in increased acceleration.
In technical terms, think of the carburetor as a tube that regulates or rather restricts the fuel delivery to increase the velocity of the air. This part which restricts the fuel is known as Venturi. With the increase in velocity of air, a low-pressure space is created, which facilitates drawing of fuel from a jet located near the venturi. This creates a concoction of air-fuel mixture that burns inside the combustion chamber. This is known as the Vacuum Venturi Effect.
Advantages of Carburetor:
While fuel injection systems may have replaced the conventional carburetors, there are advantages of carburetors as well. Below are the advantages:

Fuel Injection (FI): How Does It Work
Fuel injection system comprises a complex set of electronic components and sensors. The system depends on a fuel pump to control the flow of fuel to the combustion chamber. This fuel pump is located inside the fuel tank of the bike. The supply of fuel to the combustion chamber is enabled through an Electronic Control Unit (ECU). This electric brain constantly monitors and makes complex calculations to deliver the best possible air-fuel mixture.
The complex calculations include parameters such as throttle position, engine speed, engine temperature and load, among others. The nozzle of the fuel injection system goes right into the chamber of the cylinder. Hence, the ECU directs the injectors to control the amount of fuel to enable the most efficient mode of combustion.
Performance: The ECU is constantly working on complex calculations to offer the best performance of the engine. The carburetors struggle when it comes to ever-changing fuel temperature and air pressure.
Mileage: FI system provides an accurate measurement of fuel and air resulting in higher performance of the engine which leads to better fuel management and mileage. The ECU can be mapped for a higher power ratio if you require.
Maintenance: This is the only category where the carburetor is better compared to the fuel injection system. Carburetors can easily be repaired or replaced while FI systems require professional help which can lead to higher costs.
