It is never relaxing to listen to an injector noise on your Fiat Punto 2. It is a noise that arises regularly, usually when you accelerate or your engine is idling. However, this sign may be relating to multiple kind of complications with your automobile injectors. It may not be anything severe, but when a recurrent noise happens, you have to be sure. Most importantly since fixing your Fiat Punto 2’s injectors can be costly. That’s why our team chose to prepare this article content in order to help you see more clearly, learn about the different conceivable failures and distinguish your trouble. To do this, we will first look at the normal running and usefulness of the injectors in your Fiat Punto 2, then at the conceivable reasons from which an injector noise may come.injector-noise-fiat-punto-2

Benefits of the injectors

Injectors are a very vital part of the operation of your engine. They were released to the modern vehicles about 20 years ago. Before their introduction, 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 precisely (quantity of fuel injected, air/fuel mixture) via the analysis of the data collected from the various sensors equipping the automobile (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 reasons of a clicking or knocking noise coming from the injectors of your Fiat Punto 2

Experiencing injector noises on your Fiat Punto 2 may come from different locations, we will now focus on the potential causes of these. Generally, the common 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 prevent them. If you listen to another clicking noise but it is not from your injectors, we suggest you to examine this article content about clicking noise on Fiat Punto 2 to find the reason.

The causes for injector clicking or knocking noise Fiat Punto 2

A clicking or knocking noise from your injectors can be explained for different causes. Indeed, the injectors of your Fiat Punto 2 have three main tasks, to control the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to facilitate its combustion. Then, its objective is to deal with the air/fuel dosage and at last the homogeneity of the mixture, always with the target of improving combustion. If one of these three tasks 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 due to bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will trigger thoses knocking or clicking noises on your Fiat Punto 2. The main reason of these situations in most cases originates from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible obstruction will inevitably cause a malfunction of the injector.

The consequences of injector noise on Fiat Punto 2

Now that we have reviewed the diverse reasons for injector noise on your Fiat Punto 2, we will end by stating the possible end result 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 quickly become considerable….
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 experienced by drivers is a serious loss of power. Indeed, 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 quickly damage your cylinders or pistons and your engine may tighten.
Here are three little recommendations 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 changing your diesel fuel filter regularly>
