It is hardly ever pleasant to hear an injector noise on your Peugeot 5008. It is a noise that comes up repeatedly, usually when you accelerate or your engine is idling. However, this indication may be linked to different kind of complications with your car injectors. It may not be anything severe, but when a continuing noise happens, you have to be sure. Specifically since fixing your Peugeot 5008’s injectors can be costly. That’s why our team decided to prepare 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 running and usefulness of the injectors in your Peugeot 5008, then at the conceivable reasons from which an injector noise may come.
Functions of the injectors
Injectors are a very vital part of the operation of your engine unit. 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 possibility, thanks to the injectors pump, to control electronically each stage of the intake process very accurately (quantity of fuel injected, air/fuel mixture) via the analysis of the data received from the various sensors equipping the car (engine temperature, acceleration level, engine speed, etc.). Their goal 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 Peugeot 5008
Finding out injector noises on your Peugeot 5008 may result from different locations, we will now look into the potential causes of these. In most cases, the usual noise of a faulty injector is of the snap type. Here are the several sources of these noises and the solutions to be put into practice to get rid of them. If you hear another clicking noise but it is not from your injectors, we recommend you to go through this content page about clicking noise on Peugeot 5008 to discover the cause.
The reasons for injector clicking or knocking noise Peugeot 5008
A clicking or knocking noise from your injectors can be justified by different reasons. Indeed, the injectors of your Peugeot 5008 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 goal is to control 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 functionality 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 trigger thoses knocking or clicking noises on your Peugeot 5008. The main cause of these problems commonly comes from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible blockage will inevitably lead to a malfunction of the injector. If after checking, this noise comes from another component of the engine of your Peugeot 5008, browse this content page for more infos.
The consequences of injector noise on Peugeot 5008
Now that we have reviewed the diverse causes for injector noise on your Peugeot 5008, we will end by stating the possible side 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 side effects which can 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 felt by drivers is a severe loss of power. Indeed, if your engine is running on 3 out of 4 cylinders for example, you will obviously have a loss of power
Finally, you risk deteriorating one of your pistons or your engine. Poor combustion will quickly affect your cylinders or pistons and your engine may tighten.
Here are three little tips 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>
