It is rarely ever relaxing to experience an injector noise on your Kia Forte. It is a noise that comes up regularly, usually when you accelerate or your engine is idling. However, this symptom may be related to different types of concerns with your vehicle injectors. It may not be anything major, but when a frequent noise appears, you have to be sure. Most importantly since fixing your Kia Forte’s injectors can be costly. That’s why our team chose to prepare this content in order to support you see more clearly, learn about the different plausible failures and determine your issue. To do this, we will first look at the normal functioning and usefulness of the injectors in your Kia Forte, then at the plausible causes from which an injector noise may come.
Functions of the injectors
Injectors are a very important component of the operation of your engine unit. 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 opportunity, 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 received from the various sensors equipping the vehicle (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 causes of a clicking or knocking noise caused by the injectors of your Kia Forte
Listening injector noises on your Kia Forte may originate from different origins, we will now look into the potential triggers of these. In general, the regular noise of a faulty injector is of the snap type. Here are the several sources of these noises and the solutions to be put into practice to get rid of them. If you experience another clicking noise but it is not from your injectors, we advise you to read this content about clicking noise on Kia Forte to locate the reason.
The causes for injector clicking or knocking noise Kia Forte
A clicking or knocking noise from your injectors can be explained for different causes. Indeed, the injectors of your Kia Forte 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 objective is to deal with the air/fuel dosage and at last the homogeneity of the mixture, always with the goal of improving combustion. If one of these three characteristics is altered, 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 trigger thoses knocking or clicking noises on your Kia Forte. The main reason of these trouble generally comes 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.

The effects of injector noise on Kia Forte
Now that we have analyzed the different reasons for injector noise on your Kia Forte, 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 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 known consequences felt by drivers is a noticeable loss of power. Indeed, if your engine is running on 3 out of 4 cylinders for example, you will undoubtedly have a loss of power
Finally, you risk deteriorating one of your pistons or your engine. Poor combustion will quickly harm your cylinders or pistons and your engine may tighten.
Here are three little tips to limit the risks linked 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>
