It is rarely ever relaxing to experience an injector noise on your Ford E Series. It is a noise that comes up continually, usually when you accelerate or your engine is idling. However, this indicator may be relating to different types of concerns with your car injectors. It may not be anything severe, but when a recurrent noise shows up, you have to be sure. Most importantly since repairing your Ford E Series’s injectors can be costly. That’s why our team chose to create this article in order to support you see more clearly, learn about the different plausible failures and establish your problem. To do this, we will first look at the normal functioning and usefulness of the injectors in your Ford E Series, then at the plausible triggers from which an injector noise may come.
Purposes of the injectors
Injectors are a very fundamental element of the operation of your engine unit. They were introduced 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 opportunity, 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 compiled 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 coming from the injectors of your Ford E Series
Experiencing injector noises on your Ford E Series may result from different sources, we will now concentrate on the potential causes of these. Generally, 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 adopted to prevent them. If you experience another clicking noise but it is not from your injectors, we suggest you to read this article about clicking noise on Ford E Series to discover the cause.
The causes for injector clicking or knocking noise Ford E Series
A clicking or knocking noise from your injectors can be justified by different causes. Indeed, the injectors of your Ford E Series have three main tasks, to control the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to ease its combustion. Then, its mission is to deal with the air/fuel dosage and finally the homogeneity of the mixture, always with the goal of improving combustion. If one of these three functions is modified, the main role of the injectors will be disturbed and this will lead to poor combustion. This bad combustion will be a violent explosion in the cylinders resulting from bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will induce thoses knocking or clicking noises on your Ford E Series. The main cause of these trouble in most cases originates from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible blockage will inevitably produce a malfunction of the injector. If after checking, this noise originates from another part of the engine of your Ford E Series, have a look at this article for more informations.
The end result of injector noise on Ford E Series
Now that we have analyzed the diverse reasons for injector noise on your Ford E Series, we will end by stating the possible side effects of malfunctioning one or more of your injectors. Whether only one is blocked, or broken, or your entire fuel rail is involved, you cannot escape these repercussions which can quickly become serious….
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 common consequences noticed by drivers is a significant loss of power. Indeed, if your engine is running on 3 out of 4 cylinders for example, you will inevitably have a loss of power
Finally, you risk deteriorating one of your pistons or your engine. Poor combustion will quickly damage your cylinders or pistons and your engine may tighten.
Here are three little tips to limit the risks associated 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 swapping your diesel fuel filter regularly>
