It is never pleasant to hear an injector noise on your Ford C-max. It is a noise that happens repeatedly, usually when you accelerate or your engine is idling. However, this sign may be related to different kind of complications with your automobile injectors. It may not be anything serious, but when a repeated noise appears, you have to be sure. Specifically since fixing your Ford C-max’s injectors can be expensive. That’s why our team chose to produce this content page in order to support you see more clearly, learn about the different plausible failures and distinguish your problem. To do this, we will first look at the normal functioning and usefulness of the injectors in your Ford C-max, then at the plausible reasons from which an injector noise may come.
Benefits of the injectors
Injectors are a very vital part of the operation of your engine unit. They were launched to the modern automobiles about 20 years ago. Before their appearance, 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 compiled from the various sensors equipping the automobile (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 caused by the injectors of your Ford C-max
Experiencing injector noises on your Ford C-max may result from different locations, we will now look into the potential triggers of these. In most cases, 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 applied to eliminate them. If you hear another clicking noise but it is not from your injectors, we suggest you to go through this content page about clicking noise on Ford C-max to discover the reason.
The reasons for injector clicking or knocking noise Ford C-max
A clicking or knocking noise from your injectors can be justified by different reasons. In fact, the injectors of your Ford C-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 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 induce thoses knocking or clicking noises on your Ford C-max. The main reason of these trouble generally originates from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible blockage will inevitably end in a malfunction of the injector. If after verifying, this noise originates from another component of the engine of your Ford C-max, read this content page for more infos.
The consequences of injector noise on Ford C-max
Now that we have reviewed the several reasons for injector noise on your Ford C-max, we will end by stating the possible end result 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 almost instantly become major….
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 consequences 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 undoubtedly have a loss of power
Finally, you risk deteriorating one of your pistons or your engine. Poor combustion will almost instantly affect your cylinders or pistons and your engine may tighten.
Here are three little recommendations to limit the risks relating 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 swapping your diesel fuel filter regularly>
