It is hardly ever relaxing to listen to an injector noise on your Renault Trafic. It is a noise that appears frequently, usually when you accelerate or your engine is idling. However, this indication may be relating to multiple sort of complications with your vehicle injectors. It may not be anything major, but when a repeated noise shows up, you have to be sure. Especially since replacing your Renault Trafic’s injectors can be expensive. That’s why our team decided to prepare this article content in order to support you see more clearly, learn about the different conceivable failures and establish your trouble. To do this, we will first look at the normal function and usefulness of the injectors in your Renault Trafic, then at the conceivable triggers from which an injector noise may come.
Purposes of the injectors
Injectors are a very important element of the operation of your engine unit. They were launched 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 accumulated 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 reasons of a clicking or knocking noise coming from the injectors of your Renault Trafic
Experiencing injector noises on your Renault Trafic may result from different origins, we will now look into the potential triggers of these. In most cases, the common noise of a faulty injector is of the snap type. Here are the different origins of these noises and the solutions to be put into practice to get rid of them. If you listen to another clicking noise but it is not from your injectors, we advise you to examine this article content about clicking noise on Renault Trafic to locate the trigger.
The explanations for injector clicking or knocking noise Renault Trafic
A clicking or knocking noise from your injectors can be justified by different explanations. In fact, the injectors of your Renault Trafic have three main missions, to manage the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to ease its combustion. Then, its goal is to manage the air/fuel dosage and at last the homogeneity of the mixture, always with the goal of improving combustion. If one of these three features is altered, the main role of the injectors will be disrupted and this will lead to poor combustion. This bad combustion will be a violent explosion in the cylinders as a consequence of bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will induce thoses knocking or clicking noises on your Renault Trafic. The main trigger of these trouble generally originates from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible blockage will inevitably result in a malfunction of the injector.

The side effects of injector noise on Renault Trafic
Now that we have reviewed the different reasons for injector noise on your Renault Trafic, we will end by stating the possible side effects 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 consequences which can promptly become serious….
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 effects 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 degrading one of your pistons or your engine. Poor combustion will promptly affect your cylinders or pistons and your engine may tighten.
Here are three little tips 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 changing your diesel fuel filter regularly>
