It is hardly ever relaxing to acknowledge an injector noise on your Citroen C6. It is a noise that appears continually, usually when you accelerate or your engine is idling. However, this indication may be connected to several kind of problems with your vehicle injectors. It may not be anything serious, but when a continuing noise shows up, you have to be sure. Most importantly since repairing your Citroen C6’s injectors can be costly. That’s why our team chose to compose this content page in order to support you see more clearly, learn about the different plausible failures and distinguish your issue. To do this, we will first look at the normal running and usefulness of the injectors in your Citroen C6, then at the plausible triggers from which an injector noise may come.
Purposes 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 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 collected from the various sensors equipping the vehicle (engine temperature, acceleration level, engine speed, etc.). Their aim 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 coming from the injectors of your Citroen C6
Hearing injector noises on your Citroen C6 may originate from different sources, we will now focus on the potential triggers of these. In most cases, the usual noise of a faulty injector is of the snap type. Here are the different origins of these noises and the solutions to be adopted to prevent them. If you acknowledge another clicking noise but it is not from your injectors, we suggest you to examine this content page about clicking noise on Citroen C6 to find the trigger.
The reasons for injector clicking or knocking noise Citroen C6
A clicking or knocking noise from your injectors can be justified by different reasons. In fact, the injectors of your Citroen C6 have three main missions, to control the vaporisation of the fuel, i.e., to convert 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 goal of improving combustion. If one of these three functions 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 because of bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will provoke thoses knocking or clicking noises on your Citroen C6. The main trigger of these situations usually comes 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 comes from another element of the engine of your Citroen C6, have a look at this content page for more informations.
The consequences of injector noise on Citroen C6
Now that we have reviewed the different reasons for injector noise on your Citroen C6, we will end by stating the possible side effects 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 quickly become serious….
First, you risk destroying your exhaust system 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 felt by drivers is a distinctive 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 degrading one of your pistons or your engine. Poor combustion will quickly damage 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>
