It is hardly ever relaxing to hear an injector noise on your Renault Espace 3. It is a noise that happens repeatedly, usually when you accelerate or your engine is idling. However, this indication may be connected to multiple sort of problems with your vehicle injectors. It may not be anything severe, but when a repeated noise shows up, you have to be sure. Especially since repairing your Renault Espace 3’s injectors can be costly. That’s why our team decided to produce this article content 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 Espace 3, then at the conceivable reasons from which an injector noise may come.
Functions of the injectors
Injectors are a very important component of the operation of your engine motor. They were introduced 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 ability, 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 goal 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 triggers of a clicking or knocking noise caused by the injectors of your Renault Espace 3
Hearing injector noises on your Renault Espace 3 may originate from different origins, we will now focus on the potential triggers of these. In most cases, 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 eliminate them. If you hear another clicking noise but it is not from your injectors, we recommend you to read this article content about clicking noise on Renault Espace 3 to find the reason.
The reasons for injector clicking or knocking noise Renault Espace 3
A clicking or knocking noise from your injectors can be justified by different reasons. Indeed, the injectors of your Renault Espace 3 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 task is to control the air/fuel dosage and at last the homogeneity of the mixture, always with the target of improving combustion. If one of these three attributes 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 due to bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will induce thoses knocking or clicking noises on your Renault Espace 3. The main reason of these situations generally originates from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible blockage will inevitably cause a malfunction of the injector. If after verifying, this noise originates from another element of the engine of your Renault Espace 3, check this article content for more informations.
The consequences of injector noise on Renault Espace 3
Now that we have reviewed the several causes for injector noise on your Renault Espace 3, 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 effects which can promptly 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 regular repercussions felt by drivers is a significant loss of power. Indeed, if your engine is running on 3 out of 4 cylinders for example, you will inevitably have a loss of power
Finally, you risk degrading one of your pistons or your engine. Poor combustion will promptly harm 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>
