It is hardly ever pleasant to listen to an injector noise on your Fiat Tipo. It is a noise that arises repeatedly, usually when you accelerate or your engine is idling. However, this indicator may be linked to several sort of concerns with your car injectors. It may not be anything severe, but when a persistent noise arises, you have to be sure. Especially since replacing your Fiat Tipo’s injectors can be expensive. That’s why our team decided to compose this content in order to help you see more clearly, learn about the different possible failures and establish your trouble. To do this, we will first look at the normal functioning and usefulness of the injectors in your Fiat Tipo, then at the possible causes from which an injector noise may come.
Functions of the injectors
Injectors are a very vital component of the operation of your engine unit. They were launched to the modern cars 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 possibility, 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 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 coming from the injectors of your Fiat Tipo
Finding out injector noises on your Fiat Tipo may result from different locations, we will now concentrate on the potential causes of these. In most cases, the usual 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 get rid of them. If you listen to another clicking noise but it is not from your injectors, we encourage you to examine this content about clicking noise on Fiat Tipo to locate the cause.
The causes for injector clicking or knocking noise Fiat Tipo
A clicking or knocking noise from your injectors can be justified by different causes. In fact, the injectors of your Fiat Tipo have three main missions, to manage 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 goal of improving combustion. If one of these three functions 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 due to bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will induce thoses knocking or clicking noises on your Fiat Tipo. The main cause of these concerns in most cases originates from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible obstruction will inevitably cause a malfunction of the injector. If after verifying, this noise originates from another element of the engine of your Fiat Tipo, have a look at this content for more informations.
The end result of injector noise on Fiat Tipo
Now that we have reviewed the different causes for injector noise on your Fiat Tipo, we will end by stating the possible effects of malfunctioning one or more of your injectors. Whether only one is clogged, or damaged, or your entire fuel rail is involved, you cannot escape these side effects which can fairly quickly 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 common consequences experienced by drivers is a serious 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 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>
