It is rarely ever pleasurable to acknowledge an injector noise on your Renault Kadjar. It is a noise that arises continually, usually when you accelerate or your engine is idling. However, this indication may be connected to several types of concerns with your automobile injectors. It may not be anything severe, but when a persistent noise arises, you have to be sure. Specifically since replacing your Renault Kadjar’s injectors can be expensive. That’s why our team decided to compose this content page in order to support you see more clearly, learn about the different plausible failures and establish your problem. To do this, we will first look at the normal function and usefulness of the injectors in your Renault Kadjar, then at the plausible reasons 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 introduced 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 collected from the various sensors equipping the automobile (engine temperature, acceleration level, engine speed, etc.). Their objective 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 Kadjar
Finding out injector noises on your Renault Kadjar may come from different sources, we will now concentrate on the potential triggers of these. In general, 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 put into practice to stop them. If you acknowledge another clicking noise but it is not from your injectors, we suggest you to examine this content page about clicking noise on Renault Kadjar to locate the reason.
The explanations for injector clicking or knocking noise Renault Kadjar
A clicking or knocking noise from your injectors can be explained for different explanations. In fact, the injectors of your Renault Kadjar have three main tasks, to manage the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to facilitate its combustion. Then, its task is to manage the air/fuel dosage and finally the homogeneity of the mixture, always with the target of improving combustion. If one of these three functions is modified, the main role of the injectors will be disturbed and this will lead to poor combustion. This bad combustion will be a violent explosion in the cylinders because of bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will induce thoses knocking or clicking noises on your Renault Kadjar. The main reason of these concerns in most cases 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 Kadjar, check this content page for more infos.
The consequences of injector noise on Renault Kadjar
Now that we have analyzed the diverse reasons for injector noise on your Renault Kadjar, we will end by stating the possible side effects 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 fairly quickly become critical….
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 common repercussions felt 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 surely have a loss of power
Finally, you risk deteriorating one of your pistons or your engine. Poor combustion will fairly quickly damage your cylinders or pistons and your engine may tighten.
Here are three little tips to limit the risks linked 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>
