It is hardly ever pleasurable to perceive an injector noise on your Citroen Saxo. It is a noise that comes up regularly, usually when you accelerate or your engine is idling. However, this symptom may be related to several sort of trouble with your vehicle injectors. It may not be anything serious, but when a recurrent noise arises, you have to be sure. Most importantly since repairing your Citroen Saxo’s injectors can be expensive. That’s why our team chose to create this content page in order to help you see more clearly, learn about the different plausible failures and establish your problem. To do this, we will first look at the normal functioning and usefulness of the injectors in your Citroen Saxo, then at the plausible reasons from which an injector noise may come.
Benefits of the injectors
Injectors are a very fundamental element 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 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 accumulated 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 obtain the best possible combustion in the cylinders.
The different reasons of a clicking or knocking noise coming from the injectors of your Citroen Saxo
Finding out injector noises on your Citroen Saxo may originate from different locations, we will now concentrate on the potential triggers of these. Generally, the usual noise of a faulty injector is of the snap type. Here are the different origins of these noises and the solutions to be put into practice to get rid of them. If you perceive another clicking noise but it is not from your injectors, we encourage you to examine this content page about clicking noise on Citroen Saxo to locate the cause.
The explanations for injector clicking or knocking noise Citroen Saxo
A clicking or knocking noise from your injectors can be justified by different explanations. Indeed, the injectors of your Citroen Saxo have three main missions, to control the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to ease its combustion. Then, its goal is to control the air/fuel dosage and at last the homogeneity of the mixture, always with the goal of improving combustion. If one of these three attributes is modified, 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 because of bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will trigger thoses knocking or clicking noises on your Citroen Saxo. The main cause of these problems commonly comes from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible obstruction will inevitably end in a malfunction of the injector. If after checking, this noise comes from another part of the engine of your Citroen Saxo, read this content page for more infos.
The side effects of injector noise on Citroen Saxo
Now that we have analyzed the several causes for injector noise on your Citroen Saxo, we will end by stating the possible consequences 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 consequences which can fairly quickly become serious….
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 experienced 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 fairly quickly 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 changing your diesel fuel filter regularly>
