It is rarely ever enjoyable to notice an injector noise on your Peugeot 205. It is a noise that appears repeatedly, usually when you accelerate or your engine is idling. However, this sign may be connected to several kind of concerns with your automobile injectors. It may not be anything major, but when a persistent noise comes out, you have to be sure. Specifically since repairing your Peugeot 205’s injectors can be costly. That’s why our team chose to prepare this article 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 function and usefulness of the injectors in your Peugeot 205, then at the conceivable triggers from which an injector noise may come.
Purposes of the injectors
Injectors are a very vital part of the operation of your engine. They were launched 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 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 obtained from the various sensors equipping the automobile (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 obtain the best possible combustion in the cylinders.
The different causes of a clicking or knocking noise coming from the injectors of your Peugeot 205
Experiencing injector noises on your Peugeot 205 may result from different origins, we will now focus on the potential causes of these. Generally, 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 implemented to stop them. If you notice another clicking noise but it is not from your injectors, we recommend you to go through this article about clicking noise on Peugeot 205 to find the trigger.
The causes for injector clicking or knocking noise Peugeot 205
A clicking or knocking noise from your injectors can be explained for different causes. In fact, the injectors of your Peugeot 205 have three main missions, to manage 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 features is altered, the main purpose of the injectors will be disrupted and this will lead to poor combustion. This bad combustion will be a violent explosion in the cylinders due to bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will provoke thoses knocking or clicking noises on your Peugeot 205. The main trigger of these trouble 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 cause a malfunction of the injector. If after checking, this noise originates from another part of the engine of your Peugeot 205, check this article for more infos.
The consequences of injector noise on Peugeot 205
Now that we have analyzed the diverse reasons for injector noise on your Peugeot 205, 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 repercussions which can almost instantly 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 effects 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 surely have a loss of power
Finally, you risk deteriorating one of your pistons or your engine. Poor combustion will almost instantly affect your cylinders or pistons and your engine may tighten.
Here are three little suggestions 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>
