| Gasoline Injection System |
In this article, we are going to see about drawbacks of carburetor system in S I engines. There are various reasons for using the gasoline injection system over the carburetor system.
Drawbacks of carburetor system:
- 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.
- In multi-cylinder engines, the distribution of air-fuel mixture to the cylinder is non-uniform that causes due to resistance to air-fuel mixture flow at intake manifolds.
- Increasing or decreasing load on the engines differs from the air-fuel ratio. A.F ratio changes when the load on the engine changes.
- At low load running and idling conditions engine needs more fuel which is not economical as compared to the gasoline injection system.
- The use of compression (C.R) ration in the carburetor system is limited.
- In a multi-cylinder engine, there is always a possibility of backfiring at low speed.
- Emission at the exhaust is high which is not good for our lovely environment.
- In the winter season, the carburetor system faces ice formation issues due to low temperatures.
- The working of the carburetor can be affected by changes in the atmospheric pressure.
- The carburetor system is not economical.
Why the gasoline injection 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 the gasoline injection system over the carburetor system.
From this article, you can learn about the drawbacks of carburetor system over the gasoline fuel injection system.
