It is hardly ever pleasurable to experience an injector noise on your Fiat Doblo Cargo. It is a noise that appears frequently, usually when you accelerate or your engine is idling. However, this sign may be related to different kind of complications with your car injectors. It may not be anything severe, but when a persistent noise shows up, you have to be sure. Especially since fixing your Fiat Doblo Cargo’s injectors can be costly. That’s why our team chose to compose this content page in order to support you see more clearly, learn about the different possible failures and establish your problem. To do this, we will first look at the normal functioning and usefulness of the injectors in your Fiat Doblo Cargo, then at the possible triggers from which an injector noise may come.
Purposes of the injectors
Injectors are a very fundamental component of the operation of your engine. They were brought in to the modern vehicles about 20 years ago. Before their introduction, more conventional carburettor-type intake systems were used, 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 car (engine temperature, acceleration level, engine speed, etc.). Their goal 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 based on the injectors of your Fiat Doblo Cargo
Hearing injector noises on your Fiat Doblo Cargo may originate from different sources, we will now center on the potential triggers of these. In general, the common noise of a faulty injector is of the snap type. Here are the several sources of these noises and the solutions to be adopted to stop them. If you experience another clicking noise but it is not from your injectors, we advise you to go through this content page about clicking noise on Fiat Doblo Cargo to find the reason.
The causes for injector clicking or knocking noise Fiat Doblo Cargo
A clicking or knocking noise from your injectors can be explained for different causes. In fact, the injectors of your Fiat Doblo Cargo 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 aim of improving combustion. If one of these three features is altered, the main functionality of the injectors will be disrupted 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 Doblo Cargo. The main reason of these trouble usually originates from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible blockage will inevitably cause a malfunction of the injector.

The effects of injector noise on Fiat Doblo Cargo
Now that we have analyzed the several reasons for injector noise on your Fiat Doblo Cargo, we will end by stating the possible consequences 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 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 regular 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 obviously have a loss of power
Finally, you risk degrading one of your pistons or your engine. Poor combustion will quickly harm 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>
