It is never pleasant to hear an injector noise on your Fiat Scudo. It is a noise that comes up frequently, usually when you accelerate or your engine is idling. However, this warning sign may be relating to several types of trouble with your automobile injectors. It may not be anything serious, but when a repeated noise comes out, you have to be sure. Especially since fixing your Fiat Scudo’s injectors can be expensive. That’s why our team chose to produce this content page in order to help you see more clearly, learn about the different conceivable failures and determine your trouble. To do this, we will first look at the normal running and usefulness of the injectors in your Fiat Scudo, then at the conceivable causes from which an injector noise may come.
Functions of the injectors
Injectors are a very important part of the operation of your engine. They were released to the modern cars 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 possibility, 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 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 reasons of a clicking or knocking noise coming from the injectors of your Fiat Scudo
Listening injector noises on your Fiat Scudo may originate from different sources, we will now center on the potential causes of these. In general, the usual noise of a faulty injector is of the snap type. Here are the different origins of these noises and the solutions to be applied to eliminate them. If you hear another clicking noise but it is not from your injectors, we recommend you to examine this content page about clicking noise on Fiat Scudo to find the cause.
The causes for injector clicking or knocking noise Fiat Scudo
A clicking or knocking noise from your injectors can be justified by different causes. Indeed, the injectors of your Fiat Scudo 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 goal is to control the air/fuel dosage and at last the homogeneity of the mixture, always with the goal of improving combustion. If one of these three attributes is modified, the main purpose 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 provoke thoses knocking or clicking noises on your Fiat Scudo. The main cause of these trouble commonly comes from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible blockage will inevitably lead to a malfunction of the injector. If after checking, this noise comes from another part of the engine of your Fiat Scudo, have a look at this content page for more informations.
The side effects of injector noise on Fiat Scudo
Now that we have analyzed the several reasons for injector noise on your Fiat Scudo, we will end by stating the possible effects of malfunctioning one or more of your injectors. Whether only one is obstructed, or broken, or your entire fuel rail is involved, you cannot escape these consequences which can fairly quickly become serious….
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 effects noticed by drivers is a serious loss of power. Indeed, 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 suggestions 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>
