It is hardly ever enjoyable to experience an injector noise on your Citroen C4 Cactus. It is a noise that comes up regularly, usually when you accelerate or your engine is idling. However, this symptom may be connected to different sort of concerns with your car injectors. It may not be anything serious, but when a repeated noise comes out, you have to be sure. Especially since repairing your Citroen C4 Cactus’s injectors can be costly. That’s why our team chose to produce this content in order to help you see more clearly, learn about the different possible failures and determine your problem. To do this, we will first look at the normal running and usefulness of the injectors in your Citroen C4 Cactus, then at the possible causes from which an injector noise may come.
Attributes of the injectors
Injectors are a very vital element of the operation of your engine unit. They were released to the modern vehicles 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 opportunity, 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 received from the various sensors equipping the car (engine temperature, acceleration level, engine speed, etc.). Their goal 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 caused by the injectors of your Citroen C4 Cactus
Experiencing injector noises on your Citroen C4 Cactus may result from different locations, we will now focus on the potential causes of these. In most cases, the common 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 eliminate them. If you experience another clicking noise but it is not from your injectors, we suggest you to read this content about clicking noise on Citroen C4 Cactus to discover the reason.
The causes for injector clicking or knocking noise Citroen C4 Cactus
A clicking or knocking noise from your injectors can be justified by different causes. Indeed, the injectors of your Citroen C4 Cactus 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 goal is to manage the air/fuel dosage and at last 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 resulting from bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will induce thoses knocking or clicking noises on your Citroen C4 Cactus. The main reason of these situations usually originates from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible obstruction will inevitably lead to a malfunction of the injector.

The end result of injector noise on Citroen C4 Cactus
Now that we have reviewed the different causes for injector noise on your Citroen C4 Cactus, 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 repercussions which can almost instantly 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 known effects 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 undoubtedly 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 recommendations to limit the risks relating 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>
