It is never pleasant to acknowledge an injector noise on your Ford Fusion. It is a noise that appears repeatedly, usually when you accelerate or your engine is idling. However, this indicator may be relating to different types of concerns with your automobile injectors. It may not be anything severe, but when a repeated noise happens, you have to be sure. Especially since fixing your Ford Fusion’s injectors can be expensive. That’s why our team decided to produce this content in order to support you see more clearly, learn about the different possible failures and distinguish your trouble. To do this, we will first look at the normal function and usefulness of the injectors in your Ford Fusion, then at the possible reasons from which an injector noise may come.injector-noise-ford-fusion

Benefits of the injectors

Injectors are a very important element of the operation of your engine. They were released to the modern cars about 20 years ago. Before their appearance, more conventional carburettor-type intake systems were employed, which handled the intake of air and fuel into the engine cylinders. With the injectors, manufacturers now have the ability, thanks to the injectors pump, to control electronically each stage of the intake process very accurately (quantity of fuel injected, air/fuel mixture) via the analysis of the data received from the various sensors equipping the automobile (engine temperature, acceleration level, engine speed, etc.). Their goal is therefore to inject under high pressure a precise quantity of an air/fuel mixture at a perfect timing to get the best possible combustion in the cylinders.

The different triggers of a clicking or knocking noise based on the injectors of your Ford Fusion

Hearing injector noises on your Ford Fusion may result from different locations, we will now look into the potential triggers of these. Generally, the usual noise of a faulty injector is of the snap type. Here are the different sources of these noises and the solutions to be put into practice to get rid of them. If you acknowledge another clicking noise but it is not from your injectors, we suggest you to browse this content about clicking noise on Ford Fusion to discover the trigger.

The explanations for injector clicking or knocking noise Ford Fusion

A clicking or knocking noise from your injectors can be justified by different explanations. In fact, the injectors of your Ford Fusion have three main missions, to manage the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to facilitate its combustion. Then, its objective is to manage the air/fuel dosage and at last the homogeneity of the mixture, always with the aim of improving combustion. If one of these three characteristics is altered, the main purpose of the injectors will be disrupted and this will lead to poor combustion. This bad combustion will be a violent explosion in the cylinders as a consequence of bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will induce thoses knocking or clicking noises on your Ford Fusion. The main trigger of these concerns generally originates from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible blockage will inevitably end up in a malfunction of the injector.

The end result of injector noise on Ford Fusion

Now that we have reviewed the diverse causes for injector noise on your Ford Fusion, we will end by stating the possible side effects of malfunctioning one or more of your injectors. Whether only one is obstructed, or damaged, or your entire fuel rail is involved, you cannot escape these repercussions which can fairly quickly become considerable….
First, you risk destroying your exhaust unit in the long run, because the unburned fuel residues that will end up in your exhaust system can corrode the metal in it.
One of the most basic effects noticed by drivers is a distinctive loss of power. In fact, if your engine is running on 3 out of 4 cylinders for example, you will undoubtedly have a loss of power
Finally, you risk degrading one of your pistons or your engine. Poor combustion will fairly quickly harm your cylinders or pistons and your engine may tighten.
Here are three little tips to limit the risks linked to your injectors and protect you from engine failure:

  • Do not drive at the bottom of the tank, as you may absorb impurities
  • Use quality fuel
  • Think of changing your diesel fuel filter regularly>
