It is never pleasurable to listen to an injector noise on your Peugeot 4007. It is a noise that happens regularly, usually when you accelerate or your engine is idling. However, this indicator may be connected to multiple sort of trouble with your vehicle injectors. It may not be anything serious, but when a continuing noise happens, you have to be sure. Most importantly since fixing your Peugeot 4007’s injectors can be costly. That’s why our team chose to prepare this article content in order to support you see more clearly, learn about the different conceivable failures and distinguish your problem. To do this, we will first look at the normal running and usefulness of the injectors in your Peugeot 4007, then at the conceivable reasons from which an injector noise may come.
Attributes of the injectors
Injectors are a very significant part of the operation of your engine. They were brought in to the modern vehicles about 20 years ago. Before their appearance, 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 obtained from the various sensors equipping the vehicle (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 get the best possible combustion in the cylinders.
The different origins of a clicking or knocking noise based on the injectors of your Peugeot 4007
Discovering injector noises on your Peugeot 4007 may come from different origins, we will now center on the potential causes of these. In most cases, the typical noise of a faulty injector is of the snap type. Here are the several sources of these noises and the solutions to be implemented to stop them. If you listen to another clicking noise but it is not from your injectors, we advise you to examine this article content about clicking noise on Peugeot 4007 to find the reason.
The causes for injector clicking or knocking noise Peugeot 4007
A clicking or knocking noise from your injectors can be justified by different causes. Indeed, the injectors of your Peugeot 4007 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 task 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 features is modified, the main functionality 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 Peugeot 4007. The main reason of these problems in most cases comes from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible obstruction will inevitably end up in a malfunction of the injector. If after checking, this noise comes from another part of the engine of your Peugeot 4007, read this article content for more infos.
The effects of injector noise on Peugeot 4007
Now that we have examined the several causes for injector noise on your Peugeot 4007, we will end by stating the possible end result 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 promptly 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 effects experienced by drivers is a significant loss of power. Indeed, 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 promptly harm 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 changing your diesel fuel filter regularly>
