It is never relaxing to hear an injector noise on your Renault Maxity. It is a noise that appears frequently, usually when you accelerate or your engine is idling. However, this indication may be relating to several kind of concerns with your vehicle injectors. It may not be anything major, but when a repeated noise shows up, you have to be sure. Specifically since fixing your Renault Maxity’s injectors can be expensive. That’s why our team decided to prepare this article content in order to help you see more clearly, learn about the different plausible failures and identify your trouble. To do this, we will first look at the normal functioning and usefulness of the injectors in your Renault Maxity, then at the plausible causes from which an injector noise may come.
Functions of the injectors
Injectors are a very fundamental element of the operation of your engine unit. They were launched to the modern vehicles about 20 years ago. Before their introduction, 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 precisely (quantity of fuel injected, air/fuel mixture) via the analysis of the data received from the various sensors equipping the vehicle (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 obtain the best possible combustion in the cylinders.
The different causes of a clicking or knocking noise caused by the injectors of your Renault Maxity
Experiencing injector noises on your Renault Maxity may come from different locations, we will now center on the potential triggers of these. In most cases, the regular 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 stop them. If you hear another clicking noise but it is not from your injectors, we suggest you to read this article content about clicking noise on Renault Maxity to locate the reason.
The causes for injector clicking or knocking noise Renault Maxity
A clicking or knocking noise from your injectors can be explained for different causes. In fact, the injectors of your Renault Maxity have three main tasks, to manage the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to facilitate its combustion. Then, its objective 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 attributes 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 due to bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will trigger thoses knocking or clicking noises on your Renault Maxity. The main reason of these concerns commonly comes from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible obstruction will inevitably cause a malfunction of the injector. If after verifying, this noise comes from another part of the engine of your Renault Maxity, browse this article content for more informations.
The consequences of injector noise on Renault Maxity
Now that we have analyzed the several causes for injector noise on your Renault Maxity, we will end by stating the possible effects of malfunctioning one or more of your injectors. Whether only one is obstructed, or damaged, 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 regular consequences noticed by drivers is a noticeable loss of power. In fact, 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 fairly quickly affect your cylinders or pistons and your engine may tighten.
Here are three little suggestions to limit the risks connected 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>
