It is rarely ever relaxing to hear an injector noise on your Renault Zoe. It is a noise that appears regularly, usually when you accelerate or your engine is idling. However, this warning sign may be relating to multiple types of complications with your automobile injectors. It may not be anything serious, but when a recurrent noise happens, you have to be sure. Specifically since repairing your Renault Zoe’s injectors can be expensive. That’s why our team chose to produce this article in order to support you see more clearly, learn about the different plausible failures and distinguish your issue. To do this, we will first look at the normal running and usefulness of the injectors in your Renault Zoe, then at the plausible triggers from which an injector noise may come.
Purposes of the injectors
Injectors are a very useful part of the operation of your engine. They were launched to the modern cars 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 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 automobile (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 reasons of a clicking or knocking noise caused by the injectors of your Renault Zoe
Listening injector noises on your Renault Zoe may result from different origins, we will now focus on the potential triggers of these. In general, the usual noise of a faulty injector is of the snap type. Here are the different sources of these noises and the solutions to be applied to stop them. If you hear another clicking noise but it is not from your injectors, we recommend you to browse this article about clicking noise on Renault Zoe to discover the trigger.
The explanations for injector clicking or knocking noise Renault Zoe
A clicking or knocking noise from your injectors can be explained for different explanations. Indeed, the injectors of your Renault Zoe have three main tasks, to control 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 finally the homogeneity of the mixture, always with the goal of improving combustion. If one of these three characteristics is modified, 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 resulting from bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will induce thoses knocking or clicking noises on your Renault Zoe. The main trigger of these concerns 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 cause a malfunction of the injector. If after checking, this noise originates from another component of the engine of your Renault Zoe, browse this article for more informations.
The repercussions of injector noise on Renault Zoe
Now that we have reviewed the several reasons for injector noise on your Renault Zoe, we will end by stating the possible effects of malfunctioning one or more of your injectors. Whether only one is clogged, or broken, or your entire fuel rail is involved, you cannot escape these consequences which can fairly quickly become considerable….
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 repercussions experienced by drivers is a serious loss of power. Indeed, if your engine is running on 3 out of 4 cylinders for example, you will undoubtedly have a loss of power
Finally, you risk deteriorating one of your pistons or your engine. Poor combustion will fairly quickly harm 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 swapping your diesel fuel filter regularly>
