It is never enjoyable to hear an injector noise on your Citroen C-crosser. It is a noise that arises regularly, usually when you accelerate or your engine is idling. However, this indicator may be relating to several kind of trouble with your vehicle injectors. It may not be anything serious, but when a persistent noise arises, you have to be sure. Most importantly since fixing your Citroen C-crosser’s injectors can be costly. That’s why our team decided to create this content in order to help you see more clearly, learn about the different plausible failures and establish your trouble. To do this, we will first look at the normal running and usefulness of the injectors in your Citroen C-crosser, then at the plausible reasons from which an injector noise may come.
Attributes of the injectors
Injectors are a very important component of the operation of your engine motor. 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 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 compiled 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 coming from the injectors of your Citroen C-crosser
Discovering injector noises on your Citroen C-crosser may result from different origins, we will now focus on the potential triggers of these. In most cases, the typical noise of a faulty injector is of the snap type. Here are the different origins of these noises and the solutions to be implemented to stop them. If you hear another clicking noise but it is not from your injectors, we encourage you to go through this content about clicking noise on Citroen C-crosser to find the trigger.
The explanations for injector clicking or knocking noise Citroen C-crosser
A clicking or knocking noise from your injectors can be justified by different explanations. In fact, the injectors of your Citroen C-crosser have three main tasks, 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 control the air/fuel dosage and finally the homogeneity of the mixture, always with the goal of improving combustion. If one of these three characteristics 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 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 C-crosser. The main trigger of these problems generally comes from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible obstruction will inevitably end in a malfunction of the injector. If after verifying, this noise comes from another element of the engine of your Citroen C-crosser, have a look at this content for more informations.
The repercussions of injector noise on Citroen C-crosser
Now that we have analyzed the diverse causes for injector noise on your Citroen C-crosser, we will end by stating the possible side effects 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 fairly quickly become major….
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 known effects noticed by drivers is a serious 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 deteriorating one of your pistons or your engine. Poor combustion will fairly quickly affect your cylinders or pistons and your engine may tighten.
Here are three little suggestions 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 swapping your diesel fuel filter regularly>
