It is hardly ever relaxing to listen to an injector noise on your Peugeot 807. It is a noise that appears frequently, usually when you accelerate or your engine is idling. However, this indication may be related to multiple types of trouble with your automobile injectors. It may not be anything major, but when a frequent noise comes out, you have to be sure. Most importantly since fixing your Peugeot 807’s injectors can be expensive. That’s why our team decided to write this article content in order to help you see more clearly, learn about the different conceivable failures and identify your problem. To do this, we will first look at the normal functioning and usefulness of the injectors in your Peugeot 807, then at the conceivable causes from which an injector noise may come.
Benefits of the injectors
Injectors are a very vital part of the operation of your engine. They were released to the modern vehicles about 20 years ago. Before their appearance, 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 opportunity, 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 automobile (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 origins of a clicking or knocking noise based on the injectors of your Peugeot 807
Listening injector noises on your Peugeot 807 may originate from different locations, we will now look into the potential triggers of these. In general, the common noise of a faulty injector is of the snap type. Here are the different origins of these noises and the solutions to be put into practice to get rid of them. If you listen to another clicking noise but it is not from your injectors, we suggest you to go through this article content about clicking noise on Peugeot 807 to find the reason.
The causes for injector clicking or knocking noise Peugeot 807
A clicking or knocking noise from your injectors can be explained for different causes. In fact, the injectors of your Peugeot 807 have three main missions, to control the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to ease its combustion. Then, its objective is to control the air/fuel dosage and at last the homogeneity of the mixture, always with the target of improving combustion. If one of these three characteristics 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 because of bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will trigger thoses knocking or clicking noises on your Peugeot 807. The main reason of these trouble commonly comes from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible obstruction will inevitably produce a malfunction of the injector. If after verifying, this noise comes from another element of the engine of your Peugeot 807, check this article content for more informations.
The side effects of injector noise on Peugeot 807
Now that we have examined the diverse causes for injector noise on your Peugeot 807, 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 promptly become considerable….
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 regular effects experienced by drivers is a severe loss of power. In fact, if your engine is running on 3 out of 4 cylinders for example, you will surely have a loss of power
Finally, you risk deteriorating one of your pistons or your engine. Poor combustion will promptly affect your cylinders or pistons and your engine may tighten.
Here are three little recommendations to limit the risks connected 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>
