It is never pleasurable to perceive an injector noise on your Ford S-max. It is a noise that appears repeatedly, usually when you accelerate or your engine is idling. However, this indication may be relating to multiple kind of concerns with your car injectors. It may not be anything major, but when a repeated noise appears, you have to be sure. Specifically since replacing your Ford S-max’s injectors can be expensive. That’s why our team chose to prepare this article in order to help you see more clearly, learn about the different conceivable failures and establish your issue. To do this, we will first look at the normal functioning and usefulness of the injectors in your Ford S-max, then at the conceivable reasons from which an injector noise may come.
Attributes of the injectors
Injectors are a very useful component of the operation of your engine. They were introduced to the modern cars about 20 years ago. Before their arrival, 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 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 car (engine temperature, acceleration level, engine speed, etc.). Their aim 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 triggers of a clicking or knocking noise caused by the injectors of your Ford S-max
Experiencing injector noises on your Ford S-max may result from different sources, we will now concentrate on the potential causes of these. In general, the common noise of a faulty injector is of the snap type. Here are the different sources of these noises and the solutions to be used to stop them. If you perceive another clicking noise but it is not from your injectors, we recommend you to read this article about clicking noise on Ford S-max to discover the reason.
The explanations for injector clicking or knocking noise Ford S-max
A clicking or knocking noise from your injectors can be explained for different explanations. Indeed, the injectors of your Ford S-max have three main missions, to manage the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to ease its combustion. Then, its objective is to manage the air/fuel dosage and finally the homogeneity of the mixture, always with the goal of improving combustion. If one of these three characteristics is modified, the main functionality 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 S-max. The main reason of these concerns commonly comes from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible blockage will inevitably cause a malfunction of the injector.

The effects of injector noise on Ford S-max
Now that we have analyzed the several causes for injector noise on your Ford S-max, 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 promptly become critical….
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 regular effects experienced by drivers is a distinctive 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 deteriorating one of your pistons or your engine. Poor combustion will promptly 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>
