What are the differences between the injector and carburetor systems ?….
The main difference between the carburetor system and the injection system lies in the location and method of mixing fuel and air. The carburetor system’s air filter pulls some fuel with it when it passes through the carburator. This mixture is then distributed to the cylinders via the intake manifold.
In the injection, the fuel is sprayed in the air through the intake manifold into the combustion chamber. The fuel is injected into combustion chambers in the new direct-injection gasoline engines (FSI).
The principle behind the injection system is to get the fuel into the chamber as small as possible. The fuel will burn at its highest efficiency. Additionally, homogeneous combustion in the combustion chamber eliminates the possibility of regional combustion (knock), especially in diesel engines.
Due to the possibility of burning some of the fuel, it can extend the engine’s life and lower its emissions. The average fuel economy of the injection system is between 5% and 15%, compared to that of carburetor systems.
