It is hardly ever relaxing to experience an injector noise on your Ford Galaxy. It is a noise that appears repeatedly, usually when you accelerate or your engine is idling. However, this indication may be connected to several types of problems with your car injectors. It may not be anything major, but when a persistent noise happens, you have to be sure. Especially since fixing your Ford Galaxy’s injectors can be expensive. That’s why our team chose to write this content in order to support you see more clearly, learn about the different possible failures and determine your trouble. To do this, we will first look at the normal functioning and usefulness of the injectors in your Ford Galaxy, then at the possible causes from which an injector noise may come.
Benefits of the injectors
Injectors are a very important part of the operation of your engine. They were released to the modern vehicles 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 possibility, thanks to the injectors pump, to control electronically each stage of the intake process very precisely (quantity of fuel injected, air/fuel mixture) via the analysis of the data obtained from the various sensors equipping the car (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 obtain the best possible combustion in the cylinders.
The different causes of a clicking or knocking noise based on the injectors of your Ford Galaxy
Listening injector noises on your Ford Galaxy may come from different locations, we will now look into the potential triggers of these. In general, the common noise of a faulty injector is of the snap type. Here are the several sources of these noises and the solutions to be implemented to eliminate them. If you experience another clicking noise but it is not from your injectors, we encourage you to examine this content about clicking noise on Ford Galaxy to discover the trigger.
The reasons for injector clicking or knocking noise Ford Galaxy
A clicking or knocking noise from your injectors can be justified by different reasons. Indeed, the injectors of your Ford Galaxy 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 task is to manage the air/fuel dosage and at last the homogeneity of the mixture, always with the objective of improving combustion. If one of these three features is modified, 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 due to bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will provoke thoses knocking or clicking noises on your Ford Galaxy. The main trigger of these concerns usually originates from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible blockage will inevitably result in a malfunction of the injector.

The end result of injector noise on Ford Galaxy
Now that we have reviewed the different causes for injector noise on your Ford Galaxy, we will end by stating the possible 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 effects which can fairly quickly become severe….
First, you risk destroying your exhaust system 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 known consequences experienced by drivers is a significant loss of power. Indeed, if your engine is running on 3 out of 4 cylinders for example, you will surely have a loss of power
Finally, you risk degrading one of your pistons or your engine. Poor combustion will fairly quickly affect your cylinders or pistons and your engine may tighten.
Here are three little suggestions to limit the risks connected with 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>
