In this post, we will discuss how fuel injection system works,why it is required and how we can improve its working to make our engine fuel efficient?
Fuel injection is a system of admitting fuel into an internal combustion engine. It is a part of engine since automobile came into existence,though it is often used in Diesel or Gasoline engine only. Before ignition system, carburetor was used for fuel injection, where suction created by intake air accelerated through a Venturi tube to draw the fuel into the air stream.
So, how fuel injection is different from carburetor system?
In this system fuel is forced into the combustion chamber using atomizer nozzle at high pressure.It improves performance of engine considerably both in efficiency and performance.
Why Electronic fuel injection required?
In this system computers are used to calculate the amount of fuel requires by the engine at any given time.It is precise, reliable and cost effective system.It provides A/F ratio for all speed, load and temperature ranges.
