It is hardly ever pleasant to notice an injector noise on your Citroen Ds5. It is a noise that comes up continually, usually when you accelerate or your engine is idling. However, this warning sign may be linked to several types of complications with your vehicle injectors. It may not be anything severe, but when a persistent noise arises, you have to be sure. Specifically since repairing your Citroen Ds5’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 possible failures and establish your trouble. To do this, we will first look at the normal running and usefulness of the injectors in your Citroen Ds5, then at the possible causes from which an injector noise may come.
Functions of the injectors
Injectors are a very useful part of the operation of your engine motor. They were launched 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 compiled from the various sensors equipping the vehicle (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 caused by the injectors of your Citroen Ds5
Experiencing injector noises on your Citroen Ds5 may originate from different locations, we will now focus on the potential causes of these. Generally, the common noise of a faulty injector is of the snap type. Here are the several origins of these noises and the solutions to be put into practice to stop them. If you notice another clicking noise but it is not from your injectors, we encourage you to browse this content about clicking noise on Citroen Ds5 to find the reason.
The explanations for injector clicking or knocking noise Citroen Ds5
A clicking or knocking noise from your injectors can be explained for different explanations. Indeed, the injectors of your Citroen Ds5 have three main tasks, 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 goal of improving combustion. If one of these three features is modified, the main role 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 Ds5. The main reason of these situations generally originates from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible obstruction will inevitably end up in a malfunction of the injector. If after verifying, this noise originates from another part of the engine of your Citroen Ds5, have a look at this content for more infos.
The effects of injector noise on Citroen Ds5
Now that we have reviewed the several causes for injector noise on your Citroen Ds5, we will end by stating the possible end result of malfunctioning one or more of your injectors. Whether only one is blocked, or broken, or your entire fuel rail is involved, you cannot escape these effects which can quickly become severe….
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 repercussions noticed by drivers is a distinctive loss of power. Indeed, if your engine is running on 3 out of 4 cylinders for example, you will obviously 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 recommendations 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>
