It is rarely ever relaxing to acknowledge an injector noise on your Fiat 500 L. It is a noise that comes up regularly, usually when you accelerate or your engine is idling. However, this indication may be connected to multiple kind of complications with your automobile injectors. It may not be anything serious, but when a repeated noise happens, you have to be sure. Especially since fixing your Fiat 500 L’s injectors can be expensive. That’s why our team decided to write this content in order to support you see more clearly, learn about the different plausible failures and identify your problem. To do this, we will first look at the normal function and usefulness of the injectors in your Fiat 500 L, then at the plausible reasons from which an injector noise may come.
Functions of the injectors
Injectors are a very vital part of the operation of your engine motor. They were brought in to the modern vehicles about 20 years ago. Before their appearance, 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 causes of a clicking or knocking noise caused by the injectors of your Fiat 500 L
Finding out injector noises on your Fiat 500 L may result from different sources, we will now concentrate on the potential triggers of these. In general, 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 prevent them. If you acknowledge another clicking noise but it is not from your injectors, we recommend you to browse this content about clicking noise on Fiat 500 L to locate the trigger.
The reasons for injector clicking or knocking noise Fiat 500 L
A clicking or knocking noise from your injectors can be explained for different reasons. In fact, the injectors of your Fiat 500 L have three main missions, to control the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to facilitate its combustion. Then, its goal is to control the air/fuel dosage and at last the homogeneity of the mixture, always with the aim of improving combustion. If one of these three functions 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 because of 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 L. The main trigger of these trouble commonly originates from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible obstruction will inevitably end in a malfunction of the injector. If after checking, this noise originates from another element of the engine of your Fiat 500 L, browse this content for more informations.
The effects of injector noise on Fiat 500 L
Now that we have analyzed the several reasons for injector noise on your Fiat 500 L, we will end by stating the possible side effects 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 repercussions which can promptly become critical….
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 common repercussions experienced by drivers is a distinctive 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 recommendations 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>
