Today, gasoline and diesel are used as fuel for cars. In traditional gasolene engines air-fuel mixture is done by the corroborator whereas in direct fuel delivery system, the process is different. In this article, we'll study about how direct fuel injection system works and the advantages of direct fuel delivery system
Direct fuel injection is a fuel supply system that provides gasoline engines to burn fuel more efficiently, resulting in more power and increased fuel efficiency. In this system there is no need of the carburetor to mix the air/fuel mixture. Now,let us discuss how the direct fuel injection system works
Working of gasoline direct fuel delivery
In traditional (indirect) fuel injection system pre-mixing of air/fuel mixture in a chamber just outside the cylinder. In direct-injection system, the air/fuel are not pre-mixed; air comes in via the intake manifold where as the gasoline is injected directly into the cylinder.
GDI is an advanced injection system for gasoline engines with high operating pressures (more than 100 bars) and with advanced injection port combined with turbocharger that improves performances, and reductions in fuel consumption. GDI represents an effective powertrain system.
The Direct Injection system has the injection nozzle actually fixed to the top of the combustion chamber, usually the piston on the engine with this type of injection system has a crown shape in the top to create the needed swirl.
Gasoline direct fuel injection system works by sucking the air/fuel mixture into a cylinder.
In Direct Gasoline Injection engines, the Air/Fuel mixture is formed directly in the combustion chamber. During intake stroke only air is drawn into the intake manifold valve.
The fuel is injected at high pressure into the combustion chamber through a special injectors. The air/fuel mixture is compressed with a piston during compression stroke.
At the end of the compression stoke ignition of air/fuel mixture occurs resulting explosion which drives the piston downwards, producing power,which is used to transmit the vehicle through transmission system.
With the help of precise computer control unit, direct injection system allows more accurate control over the amount of fuel injected and injection timing. The position of the injector also allows more optimal spray pattern that breaks the gasoline into very smaller droplets. Resulting in more gasoline to burn causing more power and less pollution from each drop of gasoline. The is is the working of gasoline direct fuel injection system.

Advantages of gasoline direct fuel delivery system
Now let us discuss about the advantages of the gasoline direct fuel delivery system
- Using GDI system stating of vehicle in cold condition is easier.
- The GDI system require smaller combustion space due to which combustion happens more effectively.
- Using GDI,it reduces the 15% of the fuel consumption and increases the torque compare to other fuel injection system.
- In GDFI system,engine being operated at 14.7:1 air/fuel ratio by weight which provides more effective combustion.
- The better the fuel combustion happens the better will be the thermal efficiency of the vehicle.
- Gasoline direct injection is favored due to their efficiency, performance potential, and cleaner exhaust emission.
These are the advantages and working of gasoline direct injection system.
