It is never enjoyable to listen an injector noise on your Fiat 500. It is a noise that happens regularly, usually when you accelerate or your engine is idling. However, this indication may be related to multiple kind of complications with your automobile injectors. It may not be anything major, but when a recurrent noise comes out, you have to be sure. Specifically since repairing your Fiat 500’s injectors can be expensive. That’s why our team chose to create this article content in order to help you see more clearly, learn about the different conceivable failures and distinguish your issue. To do this, we will first look at the normal function and usefulness of the injectors in your Fiat 500, then at the conceivable triggers from which an injector noise may come.
Benefits of the injectors
Injectors are a very significant part of the operation of your engine. They were released to the modern cars 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 compiled from the various sensors equipping the automobile (engine temperature, acceleration level, engine speed, etc.). Their objective 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 causes of a clicking or knocking noise based on the injectors of your Fiat 500
Finding out injector noises on your Fiat 500 may originate from different origins, we will now concentrate on the potential causes of these. In most cases, the regular noise of a faulty injector is of the snap type. Here are the several sources of these noises and the solutions to be implemented to eliminate them. If you listen another clicking noise but it is not from your injectors, we suggest you to read this article content about clicking noise on Fiat 500 to discover the trigger.
The reasons for injector clicking or knocking noise Fiat 500
A clicking or knocking noise from your injectors can be justified by different reasons. In fact, the injectors of your Fiat 500 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 mission is to manage the air/fuel dosage and at last the homogeneity of the mixture, always with the target of improving combustion. If one of these three attributes is altered, 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 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 500. The main trigger of these concerns commonly originates from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible blockage will inevitably end up in a malfunction of the injector. If after verifying, this noise originates from another part of the engine of your Fiat 500, read this article content for more informations.
The repercussions of injector noise on Fiat 500
Now that we have analyzed the different causes for injector noise on your Fiat 500, we will end by stating the possible side effects of malfunctioning one or more of your injectors. Whether only one is clogged, or broken, or your entire fuel rail is involved, you cannot escape these side effects which can fairly quickly become critical….
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 significant loss of power. In fact, if your engine is running on 3 out of 4 cylinders for example, you will surely have a loss of power
Finally, you risk deteriorating one of your pistons or your engine. Poor combustion will fairly quickly harm your cylinders or pistons and your engine may tighten.
Here are three little tips to limit the risks relating 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>
