It is hardly ever pleasurable to hear an injector noise on your Citroen Ds4. It is a noise that appears regularly, usually when you accelerate or your engine is idling. However, this sign may be relating to different types 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 fixing your Citroen Ds4’s injectors can be expensive. That’s why our team decided to write this article content in order to help you see more clearly, learn about the different conceivable failures and distinguish your issue. To do this, we will first look at the normal function and usefulness of the injectors in your Citroen Ds4, then at the conceivable triggers from which an injector noise may come.
Attributes of the injectors
Injectors are a very significant part of the operation of your engine motor. They were released to the modern cars 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 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 collected 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 obtain the best possible combustion in the cylinders.
The different reasons of a clicking or knocking noise coming from the injectors of your Citroen Ds4
Hearing injector noises on your Citroen Ds4 may come from different origins, we will now center on the potential causes of these. In general, the usual noise of a faulty injector is of the snap type. Here are the several sources of these noises and the solutions to be implemented to prevent them. If you hear another clicking noise but it is not from your injectors, we suggest you to examine this article content about clicking noise on Citroen Ds4 to discover the reason.
The explanations for injector clicking or knocking noise Citroen Ds4
A clicking or knocking noise from your injectors can be justified by different explanations. Indeed, the injectors of your Citroen Ds4 have three main missions, to manage the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to ease its combustion. Then, its mission is to manage the air/fuel dosage and finally the homogeneity of the mixture, always with the goal of improving combustion. If one of these three tasks is altered, the main purpose of the injectors will be disturbed 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 Ds4. The main reason of these concerns in most cases originates from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible obstruction will inevitably lead to a malfunction of the injector. If after verifying, this noise originates from another part of the engine of your Citroen Ds4, read this article content for more informations.
The consequences of injector noise on Citroen Ds4
Now that we have analyzed the diverse causes for injector noise on your Citroen Ds4, 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 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 common 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 surely have a loss of power
Finally, you risk deteriorating 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 suggestions 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>
