It is never pleasurable to experience an injector noise on your Renault Trafic 2. It is a noise that happens continually, usually when you accelerate or your engine is idling. However, this symptom may be relating to several kind of complications with your vehicle injectors. It may not be anything severe, but when a persistent noise shows up, you have to be sure. Most importantly since fixing your Renault Trafic 2’s injectors can be costly. That’s why our team decided to prepare this article content in order to help you see more clearly, learn about the different plausible failures and establish your issue. To do this, we will first look at the normal functioning and usefulness of the injectors in your Renault Trafic 2, then at the plausible reasons from which an injector noise may come.
Functions of the injectors
Injectors are a very important element of the operation of your engine. They were launched to the modern vehicles about 20 years ago. Before their arrival, 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 accumulated from the various sensors equipping the vehicle (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 get the best possible combustion in the cylinders.
The different causes of a clicking or knocking noise coming from the injectors of your Renault Trafic 2
Hearing injector noises on your Renault Trafic 2 may come from different origins, we will now concentrate on 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 used to prevent them. If you experience another clicking noise but it is not from your injectors, we recommend you to examine this article content about clicking noise on Renault Trafic 2 to locate the reason.
The causes for injector clicking or knocking noise Renault Trafic 2
A clicking or knocking noise from your injectors can be justified by different causes. In fact, the injectors of your Renault Trafic 2 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 finally the homogeneity of the mixture, always with the aim of improving combustion. If one of these three tasks is modified, 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 provoke thoses knocking or clicking noises on your Renault Trafic 2. The main reason of these situations commonly originates from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible blockage will inevitably lead to a malfunction of the injector. If after verifying, this noise originates from another part of the engine of your Renault Trafic 2, check this article content for more informations.
The effects of injector noise on Renault Trafic 2
Now that we have analyzed the different causes for injector noise on your Renault Trafic 2, we will end by stating the possible effects of malfunctioning one or more of your injectors. Whether only one is obstructed, or damaged, or your entire fuel rail is involved, you cannot escape these effects which can fairly 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 basic effects experienced by drivers is a severe 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 damage 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>
