It is rarely ever pleasurable to experience an injector noise on your Fiat Punto. It is a noise that happens repeatedly, usually when you accelerate or your engine is idling. However, this sign may be related to several types of problems with your car injectors. It may not be anything major, but when a continuing noise arises, you have to be sure. Specifically since fixing your Fiat Punto’s injectors can be expensive. That’s why our team decided to produce this content page in order to support you see more clearly, learn about the different possible failures and distinguish your trouble. To do this, we will first look at the normal functioning and usefulness of the injectors in your Fiat Punto, then at the possible reasons from which an injector noise may come.
Attributes of the injectors
Injectors are a very significant component of the operation of your engine motor. They were introduced 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 precisely (quantity of fuel injected, air/fuel mixture) via the analysis of the data obtained 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 triggers of a clicking or knocking noise caused by the injectors of your Fiat Punto
Finding out injector noises on your Fiat Punto may come from different origins, we will now look into the potential triggers of these. Generally, 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 used to eliminate them. If you experience another clicking noise but it is not from your injectors, we encourage you to examine this content page about clicking noise on Fiat Punto to locate the cause.
The explanations for injector clicking or knocking noise Fiat Punto
A clicking or knocking noise from your injectors can be justified by different explanations. In fact, the injectors of your Fiat Punto 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 objective is to deal with the air/fuel dosage and finally the homogeneity of the mixture, always with the objective of improving combustion. If one of these three functions is altered, the main purpose of the injectors will be disrupted 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 Punto. The main cause of these situations generally originates from a particle that gets into the injectors. The precision 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 Punto, have a look at this content page for more informations.
The effects of injector noise on Fiat Punto
Now that we have reviewed the different reasons for injector noise on your Fiat Punto, we will end by stating the possible effects of malfunctioning one or more of your injectors. Whether only one is blocked, or damaged, or your entire fuel rail is involved, you cannot escape these effects which can fairly 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 regular effects felt by drivers is a severe 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 fairly quickly damage your cylinders or pistons and your engine may tighten.
Here are three little tips to limit the risks associated 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 swapping your diesel fuel filter regularly>
