It is hardly ever enjoyable to experience an injector noise on your Alfa Romeo 147. It is a noise that arises frequently, usually when you accelerate or your engine is idling. However, this indication may be linked to different types of complications with your automobile injectors. It may not be anything serious, but when a frequent noise happens, you have to be sure. Most importantly since fixing your Alfa Romeo 147’s injectors can be costly. That’s why our team chose to prepare this article content in order to help 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 Alfa Romeo 147, then at the possible triggers from which an injector noise may come.
Attributes of the injectors
Injectors are a very important element of the operation of your engine. 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 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 received 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 origins of a clicking or knocking noise caused by the injectors of your Alfa Romeo 147
Experiencing injector noises on your Alfa Romeo 147 may result from different locations, we will now center on the potential causes of these. Generally, 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 applied to get rid of them. If you experience another clicking noise but it is not from your injectors, we advise you to examine this article content about clicking noise on Alfa Romeo 147 to discover the reason.
The explanations for injector clicking or knocking noise Alfa Romeo 147
A clicking or knocking noise from your injectors can be justified by different explanations. Indeed, the injectors of your Alfa Romeo 147 have three main missions, to control the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to ease its combustion. Then, its mission is to deal with 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 modified, the main purpose 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 trigger thoses knocking or clicking noises on your Alfa Romeo 147. The main reason of these problems commonly originates from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible obstruction will inevitably end in a malfunction of the injector.

The effects of injector noise on Alfa Romeo 147
Now that we have reviewed the several causes for injector noise on your Alfa Romeo 147, we will end by stating the possible consequences of malfunctioning one or more of your injectors. Whether only one is blocked, or damaged, 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 basic repercussions noticed by drivers is a severe loss of power. Indeed, if your engine is running on 3 out of 4 cylinders for example, you will undoubtedly have a loss of power
Finally, you risk deteriorating one of your pistons or your engine. Poor combustion will fairly quickly damage 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 swapping your diesel fuel filter regularly>
