It is rarely ever enjoyable to listen an injector noise on your Renault Kangoo 2. It is a noise that appears frequently, usually when you accelerate or your engine is idling. However, this symptom may be relating to several sort of problems with your automobile injectors. It may not be anything major, but when a recurrent noise arises, you have to be sure. Especially since repairing your Renault Kangoo 2’s injectors can be costly. That’s why our team decided to write this content page in order to support you see more clearly, learn about the different possible failures and establish your problem. To do this, we will first look at the normal function and usefulness of the injectors in your Renault Kangoo 2, then at the possible causes from which an injector noise may come.
Benefits of the injectors
Injectors are a very important part of the operation of your engine. They were launched to the modern automobiles 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 compiled 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 coming from the injectors of your Renault Kangoo 2
Listening injector noises on your Renault Kangoo 2 may come from different sources, we will now focus on the potential causes of these. In most cases, the regular noise of a faulty injector is of the snap type. Here are the several origins of these noises and the solutions to be adopted to get rid of them. If you listen another clicking noise but it is not from your injectors, we advise you to examine this content page about clicking noise on Renault Kangoo 2 to discover the reason.
The causes for injector clicking or knocking noise Renault Kangoo 2
A clicking or knocking noise from your injectors can be explained for different causes. In fact, the injectors of your Renault Kangoo 2 have three main tasks, to manage the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to ease its combustion. Then, its task is to manage the air/fuel dosage and finally the homogeneity of the mixture, always with the objective of improving combustion. If one of these three attributes is altered, 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 resulting from bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will trigger thoses knocking or clicking noises on your Renault Kangoo 2. The main reason of these concerns generally comes from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible obstruction will inevitably lead to a malfunction of the injector. If after checking, this noise comes from another part of the engine of your Renault Kangoo 2, have a look at this content page for more informations.
The side effects of injector noise on Renault Kangoo 2
Now that we have examined the different reasons for injector noise on your Renault Kangoo 2, 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 side effects which can fairly quickly become serious….
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 basic repercussions noticed by drivers is a significant loss of power. In fact, if your engine is running on 3 out of 4 cylinders for example, you will obviously 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 relating 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 swapping your diesel fuel filter regularly>
