It is never enjoyable to perceive an injector noise on your Kia Stronic. It is a noise that appears frequently, usually when you accelerate or your engine is idling. However, this indicator may be connected to multiple sort of problems with your automobile injectors. It may not be anything severe, but when a persistent noise comes out, you have to be sure. Most importantly since replacing your Kia Stronic’s injectors can be costly. That’s why our team chose to create this article content in order to help you see more clearly, learn about the different plausible failures and establish your trouble. To do this, we will first look at the normal functioning and usefulness of the injectors in your Kia Stronic, then at the plausible causes from which an injector noise may come.
Purposes of the injectors
Injectors are a very vital component of the operation of your engine. They were brought in to the modern vehicles 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 possibility, 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 automobile (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 get the best possible combustion in the cylinders.
The different triggers of a clicking or knocking noise based on the injectors of your Kia Stronic
Listening injector noises on your Kia Stronic may originate from different sources, we will now center on the potential causes of these. In most cases, the typical noise of a faulty injector is of the snap type. Here are the several origins of these noises and the solutions to be used to get rid of them. If you perceive another clicking noise but it is not from your injectors, we suggest you to go through this article content about clicking noise on Kia Stronic to find the reason.
The reasons for injector clicking or knocking noise Kia Stronic
A clicking or knocking noise from your injectors can be explained for different reasons. Indeed, the injectors of your Kia Stronic have three main tasks, to control the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to ease its combustion. Then, its task is to deal with the air/fuel dosage and finally the homogeneity of the mixture, always with the goal of improving combustion. If one of these three attributes is modified, the main role 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 induce thoses knocking or clicking noises on your Kia Stronic. The main reason of these situations in most cases comes from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible blockage will inevitably produce a malfunction of the injector. If after verifying, this noise comes from another element of the engine of your Kia Stronic, check this article content for more informations.
The effects of injector noise on Kia Stronic
Now that we have examined the different reasons for injector noise on your Kia Stronic, we will end by stating the possible effects of malfunctioning one or more of your injectors. Whether only one is obstructed, or damaged, or your entire fuel rail is involved, you cannot escape these effects which can 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 known effects noticed by drivers is a severe 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 quickly affect your cylinders or pistons and your engine may tighten.
Here are three little recommendations 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>
