It is hardly ever pleasant to listen to an injector noise on your Fiat Grande Punto. It is a noise that appears frequently, usually when you accelerate or your engine is idling. However, this indicator may be relating to several sort of trouble with your automobile injectors. It may not be anything serious, but when a recurrent noise appears, you have to be sure. Most importantly since repairing your Fiat Grande Punto’s injectors can be costly. That’s why our team decided to create this article content in order to support you see more clearly, learn about the different possible failures and distinguish your problem. To do this, we will first look at the normal function and usefulness of the injectors in your Fiat Grande Punto, then at the possible triggers from which an injector noise may come.
Functions of the injectors
Injectors are a very vital element of the operation of your engine motor. They were launched to the modern automobiles 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 ability, 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 automobile (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 obtain the best possible combustion in the cylinders.
The different triggers of a clicking or knocking noise coming from the injectors of your Fiat Grande Punto
Finding out injector noises on your Fiat Grande Punto may result from different sources, we will now focus on the potential causes of these. In general, the regular 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 get rid of them. If you listen to another clicking noise but it is not from your injectors, we advise you to go through this article content about clicking noise on Fiat Grande Punto to locate the reason.
The explanations for injector clicking or knocking noise Fiat Grande Punto
A clicking or knocking noise from your injectors can be justified by different explanations. Indeed, the injectors of your Fiat Grande Punto have three main missions, to manage the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to ease its combustion. Then, its objective is to deal with the air/fuel dosage and at last the homogeneity of the mixture, always with the goal of improving combustion. If one of these three characteristics is altered, the main role of the injectors will be disrupted and this will lead to poor combustion. This bad combustion will be a violent explosion in the cylinders resulting from bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will trigger thoses knocking or clicking noises on your Fiat Grande Punto. The main reason of these situations generally comes from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible obstruction will inevitably result in a malfunction of the injector. If after checking, this noise comes from another element of the engine of your Fiat Grande Punto, have a look at this article content for more infos.
The consequences of injector noise on Fiat Grande Punto
Now that we have analyzed the different reasons for injector noise on your Fiat Grande Punto, we will end by stating the possible end result of malfunctioning one or more of your injectors. Whether only one is blocked, or broken, or your entire fuel rail is involved, you cannot escape these effects which can almost instantly become considerable….
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 repercussions felt by drivers is a distinctive 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 degrading 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 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 swapping your diesel fuel filter regularly>
