It is hardly ever enjoyable to notice an injector noise on your Peugeot 207. It is a noise that appears frequently, usually when you accelerate or your engine is idling. However, this sign may be linked to different types of concerns with your vehicle injectors. It may not be anything severe, but when a persistent noise appears, you have to be sure. Specifically since fixing your Peugeot 207’s injectors can be costly. That’s why our team chose to create this content in order to help you see more clearly, learn about the different conceivable failures and determine your trouble. To do this, we will first look at the normal functioning and usefulness of the injectors in your Peugeot 207, then at the conceivable causes from which an injector noise may come.
Purposes of the injectors
Injectors are a very fundamental part of the operation of your engine unit. They were launched to the modern vehicles 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 accumulated from the various sensors equipping the vehicle (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 causes of a clicking or knocking noise caused by the injectors of your Peugeot 207
Finding out injector noises on your Peugeot 207 may originate from different origins, we will now center on the potential triggers of these. In most cases, the typical 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 prevent them. If you notice another clicking noise but it is not from your injectors, we recommend you to browse this content about clicking noise on Peugeot 207 to discover the reason.
The causes for injector clicking or knocking noise Peugeot 207
A clicking or knocking noise from your injectors can be explained for different causes. Indeed, the injectors of your Peugeot 207 have three main missions, to control 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 aim of improving combustion. If one of these three tasks 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 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 Peugeot 207. The main reason of these concerns commonly originates from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible obstruction will inevitably result in a malfunction of the injector. If after checking, this noise originates from another component of the engine of your Peugeot 207, have a look at this content for more informations.
The end result of injector noise on Peugeot 207
Now that we have examined the several causes for injector noise on your Peugeot 207, we will end by stating the possible consequences 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 effects which can promptly become critical….
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 common effects felt by drivers is a noticeable loss of power. Indeed, if your engine is running on 3 out of 4 cylinders for example, you will surely 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 tips 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>
