It is hardly ever pleasant to acknowledge an injector noise on your Citroen C3 Pluriel. It is a noise that appears frequently, usually when you accelerate or your engine is idling. However, this symptom may be relating to several kind of problems with your vehicle injectors. It may not be anything severe, but when a recurrent noise comes out, you have to be sure. Especially since fixing your Citroen C3 Pluriel’s injectors can be expensive. That’s why our team chose to write this content in order to help you see more clearly, learn about the different possible failures and identify your trouble. To do this, we will first look at the normal function and usefulness of the injectors in your Citroen C3 Pluriel, then at the possible causes from which an injector noise may come.
Attributes of the injectors
Injectors are a very fundamental part of the operation of your engine unit. They were launched to the modern cars 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 accurately (quantity of fuel injected, air/fuel mixture) via the analysis of the data received 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 get the best possible combustion in the cylinders.
The different origins of a clicking or knocking noise based on the injectors of your Citroen C3 Pluriel
Listening injector noises on your Citroen C3 Pluriel may come from different sources, we will now look into the potential causes of these. In most cases, the common noise of a faulty injector is of the snap type. Here are the different sources of these noises and the solutions to be applied to eliminate them. If you acknowledge another clicking noise but it is not from your injectors, we recommend you to go through this content about clicking noise on Citroen C3 Pluriel to find the trigger.
The causes for injector clicking or knocking noise Citroen C3 Pluriel
A clicking or knocking noise from your injectors can be explained for different causes. In fact, the injectors of your Citroen C3 Pluriel have three main missions, to manage the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to ease its combustion. Then, its mission 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 features is altered, the main functionality of the injectors will be disturbed 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 provoke thoses knocking or clicking noises on your Citroen C3 Pluriel. The main trigger of these concerns usually comes from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible blockage will inevitably end in a malfunction of the injector.

The consequences of injector noise on Citroen C3 Pluriel
Now that we have analyzed the several reasons for injector noise on your Citroen C3 Pluriel, we will end by stating the possible end result of malfunctioning one or more of your injectors. Whether only one is clogged, or damaged, or your entire fuel rail is involved, you cannot escape these effects which can fairly quickly become critical….
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 regular consequences 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 harm your cylinders or pistons and your engine may tighten.
Here are three little suggestions 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>
