It is hardly ever pleasurable to experience an injector noise on your Citroen C1. It is a noise that happens repeatedly, usually when you accelerate or your engine is idling. However, this indicator may be relating to different sort of problems with your automobile injectors. It may not be anything severe, but when a continuing noise arises, you have to be sure. Specifically since replacing your Citroen C1’s injectors can be costly. That’s why our team decided to write this content in order to support you see more clearly, learn about the different plausible failures and determine your trouble. To do this, we will first look at the normal running and usefulness of the injectors in your Citroen C1, then at the plausible causes from which an injector noise may come.injector-noise-citroen-c1

Attributes of the injectors

Injectors are a very significant component of the operation of your engine motor. They were brought in to the modern automobiles 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 precisely (quantity of fuel injected, air/fuel mixture) via the analysis of the data compiled from the various sensors equipping the automobile (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 reasons of a clicking or knocking noise based on the injectors of your Citroen C1

Experiencing injector noises on your Citroen C1 may originate from different origins, we will now concentrate on the potential triggers of these. In general, the typical noise of a faulty injector is of the snap type. Here are the several sources of these noises and the solutions to be adopted to eliminate them. If you experience another clicking noise but it is not from your injectors, we recommend you to examine this content about clicking noise on Citroen C1 to locate the trigger.

The explanations for injector clicking or knocking noise Citroen C1

A clicking or knocking noise from your injectors can be explained for different explanations. Indeed, the injectors of your Citroen C1 have three main missions, to manage the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to facilitate 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 functions is modified, 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 provoke thoses knocking or clicking noises on your Citroen C1. The main trigger of these trouble commonly comes from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible obstruction will inevitably produce a malfunction of the injector. If after verifying, this noise comes from another element of the engine of your Citroen C1, read this content for more informations.

The end result of injector noise on Citroen C1

Now that we have examined the different reasons for injector noise on your Citroen C1, we will end by stating the possible effects 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 repercussions which can fairly quickly become serious….
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 repercussions felt by drivers is a serious 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 fairly quickly damage your cylinders or pistons and your engine may tighten.
Here are three little suggestions to limit the risks associated with 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>
