It is never pleasant to hear an injector noise on your Kia Sorento. It is a noise that arises continually, usually when you accelerate or your engine is idling. However, this indication may be connected to multiple sort of problems with your vehicle injectors. It may not be anything serious, but when a persistent noise comes out, you have to be sure. Specifically since replacing your Kia Sorento’s injectors can be costly. That’s why our team decided to produce this content page in order to help you see more clearly, learn about the different possible failures and distinguish your trouble. To do this, we will first look at the normal function and usefulness of the injectors in your Kia Sorento, then at the possible causes from which an injector noise may come.
Functions of the injectors
Injectors are a very vital component of the operation of your engine unit. They were introduced to the modern cars about 20 years ago. Before their appearance, 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 possibility, 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 aim 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 coming from the injectors of your Kia Sorento
Hearing injector noises on your Kia Sorento may come from different locations, 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 sources of these noises and the solutions to be applied to eliminate them. If you hear another clicking noise but it is not from your injectors, we advise you to browse this content page about clicking noise on Kia Sorento to locate the cause.
The explanations for injector clicking or knocking noise Kia Sorento
A clicking or knocking noise from your injectors can be explained for different explanations. Indeed, the injectors of your Kia Sorento have three main tasks, to manage the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to ease its combustion. Then, its task is to control the air/fuel dosage and finally the homogeneity of the mixture, always with the target of improving combustion. If one of these three functions is altered, the main purpose of the injectors will be disrupted 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 provoke thoses knocking or clicking noises on your Kia Sorento. The main cause of these trouble in most cases comes from a particle that gets into the injectors. The accuracy 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 component of the engine of your Kia Sorento, browse this content page for more informations.
The end result of injector noise on Kia Sorento
Now that we have reviewed the diverse reasons for injector noise on your Kia Sorento, we will end by stating the possible side 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 effects which can promptly become major….
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 severe loss of power. Indeed, if your engine is running on 3 out of 4 cylinders for example, you will obviously have a loss of power
Finally, you risk degrading one of your pistons or your engine. Poor combustion will promptly affect 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>
