It is rarely ever pleasant to listen to an injector noise on your CUPRA FORMENTOR. It is a noise that arises regularly, usually when you accelerate or your engine is idling. However, this indicator may be connected to different sort of problems with your car injectors. It may not be anything major, but when a repeated noise appears, you have to be sure. Specifically since fixing your CUPRA FORMENTOR’s injectors can be expensive. That’s why our team decided to write this content page in order to help you see more clearly, learn about the different conceivable failures and identify your problem. To do this, we will first look at the normal functioning and usefulness of the injectors in your CUPRA FORMENTOR, then at the conceivable reasons from which an injector noise may come.
Purposes of the injectors
Injectors are a very useful part of the operation of your engine motor. They were released to the modern vehicles 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 precisely (quantity of fuel injected, air/fuel mixture) via the analysis of the data compiled from the various sensors equipping the car (engine temperature, acceleration level, engine speed, etc.). Their purpose 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 triggers of a clicking or knocking noise based on the injectors of your CUPRA FORMENTOR
Finding out injector noises on your CUPRA FORMENTOR may result from different locations, we will now focus on the potential triggers of these. In general, the usual noise of a faulty injector is of the snap type. Here are the different origins of these noises and the solutions to be applied to prevent them. If you listen to another clicking noise but it is not from your injectors, we suggest you to go through this content page about clicking noise on CUPRA FORMENTOR to find the cause.
The reasons for injector clicking or knocking noise CUPRA FORMENTOR
A clicking or knocking noise from your injectors can be explained for different reasons. Indeed, the injectors of your CUPRA FORMENTOR have three main tasks, 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 tasks is modified, the main functionality of the injectors will be disrupted and this will lead to poor combustion. This bad combustion will be a violent explosion in the cylinders due to bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will provoke thoses knocking or clicking noises on your CUPRA FORMENTOR. The main cause of these problems usually originates from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible obstruction will inevitably produce a malfunction of the injector. If after checking, this noise originates from another element of the engine of your CUPRA FORMENTOR, browse this content page for more informations.
The consequences of injector noise on CUPRA FORMENTOR
Now that we have reviewed the several causes for injector noise on your CUPRA FORMENTOR, we will end by stating the possible end result 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 effects which can quickly become severe….
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 basic effects felt by drivers is a serious loss of power. Indeed, if your engine is running on 3 out of 4 cylinders for example, you will obviously have a loss of power
Finally, you risk degrading one of your pistons or your engine. Poor combustion will quickly damage your cylinders or pistons and your engine may tighten.
Here are three little tips 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 changing your diesel fuel filter regularly>
