It is hardly ever relaxing to perceive an injector noise on your Fiat Bravo. It is a noise that comes up frequently, usually when you accelerate or your engine is idling. However, this indication may be linked to different types of concerns with your car injectors. It may not be anything serious, but when a continuing noise comes out, you have to be sure. Specifically since replacing your Fiat Bravo’s injectors can be costly. That’s why our team chose to produce this article content in order to support you see more clearly, learn about the different conceivable failures and determine your trouble. To do this, we will first look at the normal function and usefulness of the injectors in your Fiat Bravo, then at the conceivable causes from which an injector noise may come.injector-noise-fiat-bravo

Purposes of the injectors

Injectors are a very useful component of the operation of your engine. They were introduced to the modern vehicles 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 precisely (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 aim 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 Fiat Bravo

Finding out injector noises on your Fiat Bravo may come from different sources, we will now focus on the potential triggers of these. Generally, the typical noise of a faulty injector is of the snap type. Here are the different sources of these noises and the solutions to be adopted to get rid of them. If you perceive another clicking noise but it is not from your injectors, we recommend you to go through this article content about clicking noise on Fiat Bravo to find the trigger.

The explanations for injector clicking or knocking noise Fiat Bravo

A clicking or knocking noise from your injectors can be justified by different explanations. In fact, the injectors of your Fiat Bravo have three main missions, to control the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to ease its combustion. Then, its task is to control the air/fuel dosage and finally the homogeneity of the mixture, always with the aim of improving combustion. If one of these three tasks 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 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 Fiat Bravo. The main trigger 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 blockage will inevitably result in a malfunction of the injector. If after checking, this noise originates from another part of the engine of your Fiat Bravo, read this article content for more infos.

The side effects of injector noise on Fiat Bravo

Now that we have examined the different reasons for injector noise on your Fiat Bravo, we will end by stating the possible consequences 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 promptly become major….
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 basic repercussions felt by drivers is a significant 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 promptly harm your cylinders or pistons and your engine may tighten.
Here are three little tips to limit the risks linked 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>
