It is rarely ever relaxing to hear an injector noise on your Ford Mondeo. It is a noise that comes up regularly, usually when you accelerate or your engine is idling. However, this symptom may be linked to several sort of complications with your car injectors. It may not be anything major, but when a repeated noise appears, you have to be sure. Especially since replacing your Ford Mondeo’s injectors can be costly. That’s why our team chose to prepare this content in order to help you see more clearly, learn about the different plausible failures and identify your trouble. To do this, we will first look at the normal functioning and usefulness of the injectors in your Ford Mondeo, then at the plausible reasons from which an injector noise may come.
Functions of the injectors
Injectors are a very useful component of the operation of your engine. They were launched to the modern automobiles about 20 years ago. Before their introduction, more conventional carburettor-type intake systems were used, 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 accumulated 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 get the best possible combustion in the cylinders.
The different reasons of a clicking or knocking noise coming from the injectors of your Ford Mondeo
Hearing injector noises on your Ford Mondeo may originate from different locations, we will now center on the potential causes of these. Generally, the regular noise of a faulty injector is of the snap type. Here are the different origins of these noises and the solutions to be adopted to get rid of them. If you hear another clicking noise but it is not from your injectors, we encourage you to go through this content about clicking noise on Ford Mondeo to locate the trigger.
The reasons for injector clicking or knocking noise Ford Mondeo
A clicking or knocking noise from your injectors can be explained for different reasons. In fact, the injectors of your Ford Mondeo have three main tasks, to control the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to facilitate its combustion. Then, its objective is to deal with the air/fuel dosage and at last the homogeneity of the mixture, always with the objective of improving combustion. If one of these three characteristics is modified, the main purpose of the injectors will be disturbed and this will lead to poor combustion. This bad combustion will be a violent explosion in the cylinders because of bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will trigger thoses knocking or clicking noises on your Ford Mondeo. The main trigger of these problems commonly comes from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible obstruction will inevitably cause a malfunction of the injector. If after verifying, this noise comes from another part of the engine of your Ford Mondeo, read this content for more informations.
The end result of injector noise on Ford Mondeo
Now that we have analyzed the different reasons for injector noise on your Ford Mondeo, we will end by stating the possible effects of malfunctioning one or more of your injectors. Whether only one is clogged, or damaged, or your entire fuel rail is involved, you cannot escape these consequences which can 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 regular effects felt by drivers is a noticeable loss of power. In fact, 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 suggestions 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 changing your diesel fuel filter regularly>
