It is rarely ever enjoyable to hear an injector noise on your Fiat Bravo 2. It is a noise that comes up repeatedly, usually when you accelerate or your engine is idling. However, this symptom may be related to several kind of complications with your car injectors. It may not be anything major, but when a continuing noise appears, you have to be sure. Especially since replacing your Fiat Bravo 2’s injectors can be expensive. That’s why our team decided to write this content in order to support you see more clearly, learn about the different possible failures and identify your issue. To do this, we will first look at the normal functioning and usefulness of the injectors in your Fiat Bravo 2, then at the possible triggers from which an injector noise may come.
Functions of the injectors
Injectors are a very important component of the operation of your engine. They were released to the modern vehicles about 20 years ago. Before their arrival, 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 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 collected from the various sensors equipping the car (engine temperature, acceleration level, engine speed, etc.). Their aim 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 origins of a clicking or knocking noise caused by the injectors of your Fiat Bravo 2
Experiencing injector noises on your Fiat Bravo 2 may come from different origins, we will now focus on the potential triggers of these. Generally, the common noise of a faulty injector is of the snap type. Here are the several origins of these noises and the solutions to be applied to stop them. If you hear another clicking noise but it is not from your injectors, we advise you to browse this content about clicking noise on Fiat Bravo 2 to discover the trigger.
The reasons for injector clicking or knocking noise Fiat Bravo 2
A clicking or knocking noise from your injectors can be explained for different reasons. In fact, the injectors of your Fiat Bravo 2 have three main missions, to control the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to facilitate its combustion. Then, its goal is to deal with 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 modified, 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 induce thoses knocking or clicking noises on your Fiat Bravo 2. The main trigger of these trouble generally comes from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible obstruction will inevitably result in a malfunction of the injector.

The effects of injector noise on Fiat Bravo 2
Now that we have examined the diverse reasons for injector noise on your Fiat Bravo 2, 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 consequences which can almost instantly become critical….
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 consequences noticed 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 inevitably 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 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>
