It is hardly ever relaxing to notice an injector noise on your Renault Espace. It is a noise that appears repeatedly, usually when you accelerate or your engine is idling. However, this warning sign may be related to multiple sort of complications with your vehicle injectors. It may not be anything severe, but when a recurrent noise comes out, you have to be sure. Specifically since repairing your Renault Espace’s injectors can be costly. That’s why our team chose to create this content page 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 Espace, then at the conceivable triggers from which an injector noise may come.
Functions of the injectors
Injectors are a very useful part of the operation of your engine. They were brought in to the modern cars about 20 years ago. Before their appearance, 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 compiled from the various sensors equipping the vehicle (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 get the best possible combustion in the cylinders.
The different origins of a clicking or knocking noise caused by the injectors of your Renault Espace
Discovering injector noises on your Renault Espace may come from different origins, we will now look into the potential causes of these. Generally, the common noise of a faulty injector is of the snap type. Here are the different sources of these noises and the solutions to be put into practice to get rid of them. If you notice another clicking noise but it is not from your injectors, we suggest you to go through this content page about clicking noise on Renault Espace to locate the trigger.
The causes for injector clicking or knocking noise Renault Espace
A clicking or knocking noise from your injectors can be justified by different causes. In fact, the injectors of your Renault Espace have three main missions, to manage the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to facilitate its combustion. Then, its mission is to deal with the air/fuel dosage and finally the homogeneity of the mixture, always with the target of improving combustion. If one of these three attributes 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 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 Espace. The main trigger of these trouble in most cases comes from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible obstruction will inevitably produce a malfunction of the injector. If after verifying, this noise comes from another component of the engine of your Renault Espace, check this content page for more infos.
The side effects of injector noise on Renault Espace
Now that we have analyzed the different causes for injector noise on your Renault Espace, 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 side effects which can quickly become severe….
First, you risk destroying your exhaust system 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 consequences experienced by drivers is a distinctive 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 quickly damage your cylinders or pistons and your engine may tighten.
Here are three little suggestions to limit the risks associated with 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>
