Gasoline injection system Vs Carburetor System and drawbacks of carburetor system


In the modern automobile industry, most of the companies use the gasoline injection system in SI engines. There is the availability of more efficient carburetors which are very cheap and reliable in the market but still, most of the automobile companies use gasoline injection system over the carburetor system.

There are various reasons for using gasoline injection system over the carburetor system. Let's see the drawbacks of carburetor system:

Drawbacks of carburetor system:


1. In the carburetor system, there are restrictions of the mixture of flow across the venturi tube and other metering devices in the air passage. It causes low volumetric efficiency in the carburetor.

2. In multi-cylinder engines, distribution of air-fuel mixture to the cylinder is non-uniform that causes due to resistance to air-fuel mixture flow at intake manifolds.

3. Increasing or decreasing load on the engines differs the air-fuel ratio. A.F ratio changes when the load on the engine changes.

4. At low load running and idling conditions engine needs more fuel which is not economical as compared to the gasoline injection system.

5. Use of compression (C.R) ration in the carburetor system is limited.

6. In a multi-cylinder engine, there is always a possibility of backfiring at low speed.

7. Emission at the exhaust is high which is not good for our lovely environment.

8. In the winter season, the carburetor system faces ice formation issue due to low temperature.

9. Working of the carburetor can be affected by changes in the atmospheric pressure.

10. Carburetor system is not economical.

From this article, you can learn about the drawbacks of carburetor system  over gasoline fuel injection system.
