It is never pleasant to perceive an injector noise on your Fiat Idea. It is a noise that happens repeatedly, usually when you accelerate or your engine is idling. However, this indication may be connected to several kind of concerns with your car injectors. It may not be anything serious, but when a recurrent noise happens, you have to be sure. Especially since repairing your Fiat Idea’s injectors can be costly. That’s why our team chose to create this article content in order to support you see more clearly, learn about the different plausible failures and identify your problem. To do this, we will first look at the normal functioning and usefulness of the injectors in your Fiat Idea, then at the plausible triggers from which an injector noise may come.
Functions of the injectors
Injectors are a very useful 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 accumulated 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 reasons of a clicking or knocking noise caused by the injectors of your Fiat Idea
Listening injector noises on your Fiat Idea may result from different locations, we will now look into the potential triggers of these. In most cases, the typical noise of a faulty injector is of the snap type. Here are the several sources of these noises and the solutions to be implemented to get rid of them. If you perceive another clicking noise but it is not from your injectors, we advise you to examine this article content about clicking noise on Fiat Idea to discover the cause.
The explanations for injector clicking or knocking noise Fiat Idea
A clicking or knocking noise from your injectors can be justified by different explanations. In fact, the injectors of your Fiat Idea have three main tasks, to control the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to ease its combustion. Then, its goal is to manage the air/fuel dosage and finally the homogeneity of the mixture, always with the objective 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 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 Fiat Idea. The main cause of these problems 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 produce a malfunction of the injector. If after checking, this noise originates from another part of the engine of your Fiat Idea, have a look at this article content for more infos.
The effects of injector noise on Fiat Idea
Now that we have analyzed the diverse causes for injector noise on your Fiat Idea, we will end by stating the possible side 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 repercussions which can quickly become serious….
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 regular consequences noticed 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 degrading one of your pistons or your engine. Poor combustion will quickly affect your cylinders or pistons and your engine may tighten.
Here are three little suggestions to limit the risks connected 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>
