It is rarely ever enjoyable to listen to an injector noise on your Citroen C3 Aircross. It is a noise that happens regularly, usually when you accelerate or your engine is idling. However, this warning sign may be linked to different sort of concerns with your car injectors. It may not be anything major, but when a repeated noise happens, you have to be sure. Specifically since replacing your Citroen C3 Aircross’s injectors can be expensive. That’s why our team chose to write this article 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 running and usefulness of the injectors in your Citroen C3 Aircross, then at the plausible triggers from which an injector noise may come.
Benefits of the injectors
Injectors are a very significant element of the operation of your engine motor. They were released to the modern automobiles about 20 years ago. Before their arrival, 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 ability, 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 car (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 obtain the best possible combustion in the cylinders.
The different triggers of a clicking or knocking noise caused by the injectors of your Citroen C3 Aircross
Hearing injector noises on your Citroen C3 Aircross may come from different origins, we will now look into the potential causes of these. In most cases, 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 used to stop them. If you listen to another clicking noise but it is not from your injectors, we encourage you to browse this article about clicking noise on Citroen C3 Aircross to locate the trigger.
The explanations for injector clicking or knocking noise Citroen C3 Aircross
A clicking or knocking noise from your injectors can be explained for different explanations. Indeed, the injectors of your Citroen C3 Aircross 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 goal is to manage the air/fuel dosage and at last the homogeneity of the mixture, always with the objective of improving combustion. If one of these three attributes is altered, 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 induce thoses knocking or clicking noises on your Citroen C3 Aircross. The main trigger of these trouble commonly comes from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible blockage will inevitably end in a malfunction of the injector. If after checking, this noise comes from another part of the engine of your Citroen C3 Aircross, read this article for more infos.
The end result of injector noise on Citroen C3 Aircross
Now that we have examined the different causes for injector noise on your Citroen C3 Aircross, we will end by stating the possible 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 almost instantly become severe….
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 repercussions felt by drivers is a significant loss of power. Indeed, 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 almost instantly damage your cylinders or pistons and your engine may tighten.
Here are three little tips 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>
