It is hardly ever relaxing to listen an injector noise on your Renault Trafic 3. It is a noise that appears continually, usually when you accelerate or your engine is idling. However, this indicator may be connected to different kind of concerns with your vehicle injectors. It may not be anything serious, but when a continuing noise shows up, you have to be sure. Specifically since fixing your Renault Trafic 3’s injectors can be costly. That’s why our team decided to create this article in order to support you see more clearly, learn about the different plausible failures and establish your problem. To do this, we will first look at the normal functioning and usefulness of the injectors in your Renault Trafic 3, then at the plausible reasons from which an injector noise may come.
Purposes of the injectors
Injectors are a very useful element of the operation of your engine. They were brought in to the modern automobiles 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 accurately (quantity of fuel injected, air/fuel mixture) via the analysis of the data obtained from the various sensors equipping the vehicle (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 origins of a clicking or knocking noise caused by the injectors of your Renault Trafic 3
Listening injector noises on your Renault Trafic 3 may result from different origins, we will now look into the potential causes of these. In general, the typical 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 listen another clicking noise but it is not from your injectors, we recommend you to go through this article about clicking noise on Renault Trafic 3 to locate the trigger.
The causes for injector clicking or knocking noise Renault Trafic 3
A clicking or knocking noise from your injectors can be justified by different causes. Indeed, the injectors of your Renault Trafic 3 have three main tasks, to control the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to facilitate its combustion. Then, its objective is to deal with the air/fuel dosage and finally the homogeneity of the mixture, always with the goal of improving combustion. If one of these three features 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 because of bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will provoke thoses knocking or clicking noises on your Renault Trafic 3. The main trigger of these problems in most cases comes from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible obstruction will inevitably lead to a malfunction of the injector. If after checking, this noise comes from another part of the engine of your Renault Trafic 3, have a look at this article for more informations.
The side effects of injector noise on Renault Trafic 3
Now that we have analyzed the diverse reasons for injector noise on your Renault Trafic 3, we will end by stating the possible end result of malfunctioning one or more of your injectors. Whether only one is clogged, or broken, or your entire fuel rail is involved, you cannot escape these repercussions which can quickly become major….
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 common repercussions experienced by drivers is a noticeable 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 quickly affect your cylinders or pistons and your engine may tighten.
Here are three little tips to limit the risks connected 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 changing your diesel fuel filter regularly>
