It is rarely ever pleasant to listen an injector noise on your Ford S-max 2. It is a noise that happens frequently, usually when you accelerate or your engine is idling. However, this sign may be related to several types of problems with your automobile injectors. It may not be anything severe, but when a frequent noise appears, you have to be sure. Specifically since fixing your Ford S-max 2’s injectors can be costly. That’s why our team decided to prepare this content page in order to help you see more clearly, learn about the different conceivable failures and determine your issue. To do this, we will first look at the normal functioning and usefulness of the injectors in your Ford S-max 2, then at the conceivable reasons from which an injector noise may come.
Benefits 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 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 accurately (quantity of fuel injected, air/fuel mixture) via the analysis of the data collected from the various sensors equipping the automobile (engine temperature, acceleration level, engine speed, etc.). Their objective 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 S-max 2
Finding out injector noises on your Ford S-max 2 may originate from different sources, we will now center on the potential triggers 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 eliminate them. If you listen another clicking noise but it is not from your injectors, we recommend you to go through this content page about clicking noise on Ford S-max 2 to locate the cause.
The reasons for injector clicking or knocking noise Ford S-max 2
A clicking or knocking noise from your injectors can be explained for different reasons. Indeed, the injectors of your Ford S-max 2 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 mission is to control the air/fuel dosage and at last the homogeneity of the mixture, always with the aim of improving combustion. If one of these three tasks is altered, 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 as a consequence of bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will provoke thoses knocking or clicking noises on your Ford S-max 2. The main cause of these situations 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 result in a malfunction of the injector. If after checking, this noise comes from another part of the engine of your Ford S-max 2, have a look at this content page for more infos.
The side effects of injector noise on Ford S-max 2
Now that we have analyzed the diverse reasons for injector noise on your Ford S-max 2, we will end by stating the possible side effects of malfunctioning one or more of your injectors. Whether only one is clogged, or broken, or your entire fuel rail is involved, you cannot escape these consequences which can fairly 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 known repercussions noticed by drivers is a severe 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 degrading one of your pistons or your engine. Poor combustion will fairly quickly damage 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>
