It is hardly ever pleasant to listen to an injector noise on your Peugeot 309. It is a noise that arises continually, usually when you accelerate or your engine is idling. However, this warning sign may be connected to several types of trouble with your vehicle injectors. It may not be anything serious, but when a persistent noise comes out, you have to be sure. Especially since replacing your Peugeot 309’s injectors can be costly. That’s why our team chose to create this content in order to support you see more clearly, learn about the different plausible failures and identify your problem. To do this, we will first look at the normal functioning and usefulness of the injectors in your Peugeot 309, then at the plausible causes from which an injector noise may come.
Functions of the injectors
Injectors are a very significant component of the operation of your engine. They were released to the modern vehicles about 20 years ago. Before their introduction, 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 obtained from the various sensors equipping the vehicle (engine temperature, acceleration level, engine speed, etc.). Their objective 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 based on the injectors of your Peugeot 309
Experiencing injector noises on your Peugeot 309 may come from different origins, we will now focus on the potential causes of these. In general, the regular noise of a faulty injector is of the snap type. Here are the different sources of these noises and the solutions to be applied to get rid of them. If you listen to another clicking noise but it is not from your injectors, we recommend you to examine this content about clicking noise on Peugeot 309 to locate the reason.
The explanations for injector clicking or knocking noise Peugeot 309
A clicking or knocking noise from your injectors can be explained for different explanations. In fact, the injectors of your Peugeot 309 have three main missions, to control the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to ease its combustion. Then, its mission is to deal with the air/fuel dosage and at last the homogeneity of the mixture, always with the objective of improving combustion. If one of these three tasks 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 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 309. The main reason of these situations in most cases originates from a particle that gets into the injectors. The precision 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 originates from another part of the engine of your Peugeot 309, check this content for more informations.
The end result of injector noise on Peugeot 309
Now that we have analyzed the different reasons for injector noise on your Peugeot 309, we will end by stating the possible effects 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 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 basic effects noticed 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 undoubtedly have a loss of power
Finally, you risk deteriorating one of your pistons or your engine. Poor combustion will quickly affect your cylinders or pistons and your engine may tighten.
Here are three little tips to limit the risks associated 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>
