It is never relaxing to hear an injector noise on your Ford C Max. It is a noise that appears regularly, usually when you accelerate or your engine is idling. However, this symptom may be related to different types of problems with your car injectors. It may not be anything serious, but when a persistent noise arises, you have to be sure. Most importantly since replacing your Ford C Max’s injectors can be costly. That’s why our team chose to create this content page in order to help you see more clearly, learn about the different conceivable failures and establish your problem. To do this, we will first look at the normal function and usefulness of the injectors in your Ford C Max, then at the conceivable triggers from which an injector noise may come.
Purposes of the injectors
Injectors are a very fundamental part of the operation of your engine. They were brought in 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 opportunity, 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 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 causes of a clicking or knocking noise coming from the injectors of your Ford C Max
Finding out injector noises on your Ford C Max may originate from different locations, we will now concentrate on the potential causes of these. In general, the usual noise of a faulty injector is of the snap type. Here are the several origins of these noises and the solutions to be adopted to prevent them. If you hear another clicking noise but it is not from your injectors, we advise you to read this content page about clicking noise on Ford C Max to locate the cause.
The causes for injector clicking or knocking noise Ford C Max
A clicking or knocking noise from your injectors can be explained for different causes. In fact, the injectors of your Ford C Max have three main tasks, to manage the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to ease its combustion. Then, its task is to manage the air/fuel dosage and finally the homogeneity of the mixture, always with the target of improving combustion. If one of these three functions 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 as a consequence 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 C Max. The main cause of these trouble usually comes from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible obstruction will inevitably cause a malfunction of the injector.

The repercussions of injector noise on Ford C Max
Now that we have analyzed the several reasons for injector noise on your Ford C Max, we will end by stating the possible side effects of malfunctioning one or more of your injectors. Whether only one is obstructed, or broken, 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 felt by drivers is a significant loss of power. In fact, if your engine is running on 3 out of 4 cylinders for example, you will obviously have a loss of power
Finally, you risk deteriorating 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 recommendations 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>
