It is rarely ever relaxing to hear an injector noise on your Renault Vel Satis. It is a noise that arises repeatedly, usually when you accelerate or your engine is idling. However, this sign may be linked to different types of problems with your car injectors. It may not be anything severe, but when a frequent noise arises, you have to be sure. Especially since fixing your Renault Vel Satis’s injectors can be costly. That’s why our team decided to compose this content page in order to support you see more clearly, learn about the different conceivable failures and determine your problem. To do this, we will first look at the normal running and usefulness of the injectors in your Renault Vel Satis, then at the conceivable triggers from which an injector noise may come.
Functions of the injectors
Injectors are a very vital component of the operation of your engine unit. They were brought in to the modern vehicles about 20 years ago. Before their appearance, 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 accurately (quantity of fuel injected, air/fuel mixture) via the analysis of the data received from the various sensors equipping the car (engine temperature, acceleration level, engine speed, etc.). Their purpose 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 causes of a clicking or knocking noise caused by the injectors of your Renault Vel Satis
Experiencing injector noises on your Renault Vel Satis may originate from different sources, we will now focus on the potential triggers of these. Generally, 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 implemented to get rid of them. If you hear another clicking noise but it is not from your injectors, we advise you to examine this content page about clicking noise on Renault Vel Satis to find the reason.
The causes for injector clicking or knocking noise Renault Vel Satis
A clicking or knocking noise from your injectors can be justified by different causes. Indeed, the injectors of your Renault Vel Satis have three main missions, to manage 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 altered, 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 as a consequence 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 Vel Satis. The main reason of these trouble usually comes from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible blockage will inevitably produce a malfunction of the injector. If after verifying, this noise comes from another component of the engine of your Renault Vel Satis, have a look at this content page for more infos.
The effects of injector noise on Renault Vel Satis
Now that we have reviewed the different causes for injector noise on your Renault Vel Satis, we will end by stating the possible side effects of malfunctioning one or more of your injectors. Whether only one is clogged, or damaged, or your entire fuel rail is involved, you cannot escape these consequences which can promptly 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 known effects noticed by drivers is a significant loss of power. Indeed, if your engine is running on 3 out of 4 cylinders for example, you will obviously have a loss of power
Finally, you risk degrading one of your pistons or your engine. Poor combustion will promptly 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>
