It is hardly ever pleasant to perceive an injector noise on your Peugeot 607. It is a noise that appears repeatedly, usually when you accelerate or your engine is idling. However, this sign may be related to different sort of concerns with your car injectors. It may not be anything major, but when a persistent noise appears, you have to be sure. Most importantly since replacing your Peugeot 607’s injectors can be expensive. That’s why our team decided to write this content in order to support you see more clearly, learn about the different plausible failures and determine your trouble. To do this, we will first look at the normal functioning and usefulness of the injectors in your Peugeot 607, then at the plausible reasons from which an injector noise may come.
Purposes of the injectors
Injectors are a very useful element of the operation of your engine. They were launched to the modern cars 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 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 car (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 obtain the best possible combustion in the cylinders.
The different reasons of a clicking or knocking noise based on the injectors of your Peugeot 607
Listening injector noises on your Peugeot 607 may originate from different sources, 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 different sources of these noises and the solutions to be used to stop them. If you perceive another clicking noise but it is not from your injectors, we encourage you to browse this content about clicking noise on Peugeot 607 to discover the reason.
The reasons for injector clicking or knocking noise Peugeot 607
A clicking or knocking noise from your injectors can be justified by different reasons. In fact, the injectors of your Peugeot 607 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 objective is to control the air/fuel dosage and finally the homogeneity of the mixture, always with the target 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 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 607. The main reason of these problems usually 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 verifying, this noise comes from another component of the engine of your Peugeot 607, read this content for more infos.
The end result of injector noise on Peugeot 607
Now that we have analyzed the different reasons for injector noise on your Peugeot 607, we will end by stating the possible side effects of malfunctioning one or more of your injectors. Whether only one is obstructed, 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 common consequences felt 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 inevitably have a loss of power
Finally, you risk deteriorating one of your pistons or your engine. Poor combustion will quickly harm 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>
