It is hardly ever relaxing to hear an injector noise on your Citroen C15. It is a noise that arises regularly, usually when you accelerate or your engine is idling. However, this indicator may be relating to different sort of complications with your vehicle injectors. It may not be anything major, but when a frequent noise appears, you have to be sure. Specifically since replacing your Citroen C15’s injectors can be expensive. That’s why our team decided to write this content in order to help you see more clearly, learn about the different plausible failures and distinguish your issue. To do this, we will first look at the normal function and usefulness of the injectors in your Citroen C15, then at the plausible reasons from which an injector noise may come.
Functions of the injectors
Injectors are a very important element of the operation of your engine motor. They were brought in to the modern vehicles about 20 years ago. Before their appearance, more conventional carburettor-type intake systems were employed, 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 collected 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 triggers of a clicking or knocking noise based on the injectors of your Citroen C15
Discovering injector noises on your Citroen C15 may come from different origins, we will now concentrate on the potential triggers of these. Generally, 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 used to stop them. If you hear another clicking noise but it is not from your injectors, we suggest you to go through this content about clicking noise on Citroen C15 to discover the trigger.
The explanations for injector clicking or knocking noise Citroen C15
A clicking or knocking noise from your injectors can be justified by different explanations. Indeed, the injectors of your Citroen C15 have three main tasks, to manage the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to facilitate its combustion. Then, its mission is to deal with 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 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 as a consequence 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 C15. The main trigger of these trouble commonly originates 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 verifying, this noise originates from another element of the engine of your Citroen C15, have a look at this content for more informations.
The side effects of injector noise on Citroen C15
Now that we have reviewed the different reasons for injector noise on your Citroen C15, we will end by stating the possible end result 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 considerable….
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 effects experienced 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 harm 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 changing your diesel fuel filter regularly>
