It is hardly ever pleasurable to perceive an injector noise on your Renault Laguna 3. It is a noise that appears continually, usually when you accelerate or your engine is idling. However, this warning sign may be relating to multiple sort of problems with your automobile injectors. It may not be anything severe, but when a frequent noise arises, you have to be sure. Most importantly since repairing your Renault Laguna 3’s injectors can be costly. That’s why our team chose to produce this content page in order to support you see more clearly, learn about the different conceivable failures and establish your problem. To do this, we will first look at the normal running and usefulness of the injectors in your Renault Laguna 3, then at the conceivable triggers from which an injector noise may come.
Purposes of the injectors
Injectors are a very important component of the operation of your engine. They were launched to the modern automobiles about 20 years ago. Before their arrival, 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 precisely (quantity of fuel injected, air/fuel mixture) via the analysis of the data obtained 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 get the best possible combustion in the cylinders.
The different origins of a clicking or knocking noise coming from the injectors of your Renault Laguna 3
Experiencing injector noises on your Renault Laguna 3 may originate from different sources, 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 used to get rid of them. If you perceive another clicking noise but it is not from your injectors, we advise you to read this content page about clicking noise on Renault Laguna 3 to find the trigger.
The reasons for injector clicking or knocking noise Renault Laguna 3
A clicking or knocking noise from your injectors can be explained for different reasons. In fact, the injectors of your Renault Laguna 3 have three main tasks, to manage the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to ease its combustion. Then, its goal is to control 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 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 as a consequence of bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will trigger thoses knocking or clicking noises on your Renault Laguna 3. The main trigger of these problems in most cases originates 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 verifying, this noise originates from another component of the engine of your Renault Laguna 3, have a look at this content page for more informations.
The end result of injector noise on Renault Laguna 3
Now that we have analyzed the different causes for injector noise on your Renault Laguna 3, 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 fairly quickly become severe….
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 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 surely have a loss of power
Finally, you risk degrading 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 suggestions to limit the risks linked 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>
