Know Everything About Car's Fuel Injection

Within the intake manifold, air, and fuel mix, the fuel injector injects/sprays fuel at a highly exact angle into the intake manifold. In the combustion chamber, the air-fuel combination is compressed, starting the chemical reaction that powers your engine. Learn more about the Fuel Injection of your vehicle and how to properly maintain it.

What Is A Car Fuel Injection?

Fuel injectors use electrically controlled valves that may open and close several times per second to spray fuel into a car's engine. They have an atomizing nozzle that properly distributes the gasoline or fuel for efficient burning.

How Does My Car Fuel Injection Work?

Have a look below to understand the fuel injector working process:

In petrol-powered vehicles, the fuel injection system is always indirect, with petrol pumped into the input manifold or inlet port rather than directly into the combustion chambers. Before the fuel enters the chamber, it is properly mixed with the air.

A lot of diesel engines utilize direct injection, in which the diesel is injected directly into the compressed air-filled cylinder. Others employ indirect injection, in which the diesel fuel is injected into a specifically formed pre-combustion chamber which is connected to the cylinder head by a narrow passage. The cylinder is only filled with air.

The cylinder is only filled with air. Compression heats it to where atomized fuel is injected after a compression stroke self-ignites.

How Do I Choose The Right Fuel Injector?

What Are The Common Car Fuel Injection Problems?

Some frequent problems with fuel injection are as follows:

  1. Clogged Fuel Injectors - The petrol does not reach the intake manifold because of the blocked fuel injectors. This problem is generally caused because of the build-up of rust which gives rise to the clogged fuel injection.
  1. Dirty Fuel Injection - When the fuel additives are not sprayed into the intake manifold, then a residue is left on the injectors which burn and then become crusty. This can give rise to a weak spray and then an uneven pattern.
  1. Unable to Open Injector - There can be some reasons due to which the fuel injectors would be stuck closed, which can include defective windings or rust. Now if the fuel injector does not open up, then it will not be able to perform its job of delivering petrol through the nozzle.

  1. Unable to Close the Injection - If there is a defective spring or a build-up of rust or fuel additives, then it can cause the injector to be unable to close, which can give rise to the leakages in the petrol.
  2. Leaking Fuel Injection - Leakages in the fuel system can cause bad performance, high fuel consumption and hard starting. There can be some cases in which it can be very dangerous. If there is a leakage in the external fluid, then it can cause a fire.

What Are The Steps Of Changing My Car Fuel Injection?

Keen to know about the procedure of changing the Fuel Injection? Well, we have simplified the entire procedure for you:

Follow these steps to restore the fuel injector on your specific vehicle model:

Step 1

First of all, it is essential to relieve fuel system pressure.

Step 2

Then the fuel pump relay should be located.

Step 3

A negative battery cable should be detached by utilizing a wrench.

Step 4

If there are any accessories from the top of the engine which would interfere with the removal of the fuel injector like engine cover, accessory brackets, or air cleaner assembly components, then they should be removed.

Step 5

The wiring harness from the fuel injector should be unplugged if you want to remove them.

Step 6

The mounting screws of the fuel rail with the injector should be located so that the bolts can be removed and unfasten by utilizing a ratchet, ratchet extension, and socket.

Step 7

After that, the fuel rail should be carefully lifted when you would pull the injectors from the intake manifold.

Step 8

The injector which you want to replace from the fuel rail should be detached.

Step 9

Any seals, washers, boots, or collars which might come off after pulling the injector off the fuel rail should be stored.

Step 10

The new fuel injector should be mounted on the fuel rail along with any original seals, washers, boots, or collars. The seals, as well as boots, should be replaced with brand new ones.

Step 11

The injector-mounting bolt should be screwed in by utilizing the wrench or ratchet and socket if equipped.

Step 12

The shop rags from the intake manifold should be removed and then the fuel injectors should be inserted.

Step 13

The fuel rail should be screwed in place by utilizing the ratchet, ratchet extension, and socket.

Step 14

The fuel injector should be plugged into the wiring harness.

Step 15

Any accessories you removed to gain access to the fuel rail should be installed. Use the wrench or ratchet and socket as per the requirement.

Step 16

The ground, battery cable should be attached by utilizing the wrench.

FAQ
Cleaning fuel injectors is a service that many dealers and repair shops recommend. It may not be essential unless there are visible indicators of clogged fuel injectors (such as a rough idle, stalling, poor acceleration, or excessive emissions levels).
Fuel injectors use electrically controlled valves that may open and close multiple times per second to spray fuel into a car's engine. They have an atomizing nozzle that properly distributes the gasoline or fuel for efficient burning.
It is advised that you clean your fuel injectors every 60,000 to 90,000 kilometers. If you've observed a significant drop in your fuel efficiency, a loss of power in your vehicle, or a sluggish feeling when accelerating, you may require a fuel injection cleaning service.
However, if a fuel injector cracks or breaks, it must be replaced, which can be costly. Although each fuel injector is unique, they are meant to work together with the other injectors as a team. So, if you're wondering if you should replace one injector or all of them, the answer is usually all of them.
Unlike installing a low restriction air filter, changing fuel injectors is not a “plug-and-play” performance upgrade. It's something that necessitates an understanding of how the fuel delivery system operates. If done incorrectly, changing fuel injectors might reduce engine output.
