It is rarely ever enjoyable to listen to an injector noise on your Ford Focus C-max. It is a noise that comes up continually, usually when you accelerate or your engine is idling. However, this warning sign may be linked to several types of trouble with your automobile injectors. It may not be anything major, but when a repeated noise happens, you have to be sure. Most importantly since fixing your Ford Focus C-max’s injectors can be expensive. That’s why our team chose to write this content in order to support you see more clearly, learn about the different plausible failures and identify your issue. To do this, we will first look at the normal function and usefulness of the injectors in your Ford Focus C-max, then at the plausible causes from which an injector noise may come.
Functions of the injectors
Injectors are a very important element of the operation of your engine motor. They were released 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 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 received 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 obtain the best possible combustion in the cylinders.
The different causes of a clicking or knocking noise coming from the injectors of your Ford Focus C-max
Discovering injector noises on your Ford Focus C-max may result from different sources, we will now concentrate on the potential triggers of these. In most cases, the regular noise of a faulty injector is of the snap type. Here are the several sources of these noises and the solutions to be applied to stop them. If you listen to another clicking noise but it is not from your injectors, we suggest you to browse this content about clicking noise on Ford Focus C-max to locate the trigger.
The causes for injector clicking or knocking noise Ford Focus C-max
A clicking or knocking noise from your injectors can be explained for different causes. In fact, the injectors of your Ford Focus 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 mission is to manage the air/fuel dosage and at last the homogeneity of the mixture, always with the objective of improving combustion. If one of these three features is altered, 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 induce thoses knocking or clicking noises on your Ford Focus C-max. The main trigger of these trouble usually originates from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible obstruction will inevitably end up in a malfunction of the injector. If after verifying, this noise originates from another part of the engine of your Ford Focus C-max, read this content for more infos.
The consequences of injector noise on Ford Focus C-max
Now that we have examined the different reasons for injector noise on your Ford Focus C-max, we will end by stating the possible effects of malfunctioning one or more of your injectors. Whether only one is obstructed, or damaged, or your entire fuel rail is involved, you cannot escape these repercussions which can almost instantly become severe….
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 known consequences felt by drivers is a serious 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 tips to limit the risks connected 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>
