It is rarely ever relaxing to perceive an injector noise on your Kia E Niro. It is a noise that happens continually, usually when you accelerate or your engine is idling. However, this symptom may be linked to several sort of concerns with your car injectors. It may not be anything major, but when a frequent noise arises, you have to be sure. Specifically since replacing your Kia E Niro’s injectors can be expensive. That’s why our team chose to compose this content in order to help you see more clearly, learn about the different possible failures and establish your problem. To do this, we will first look at the normal function and usefulness of the injectors in your Kia E Niro, then at the possible reasons from which an injector noise may come.injector-noise-kia-e-niro

Functions of the injectors

Injectors are a very vital part of the operation of your engine. They were launched to the modern vehicles about 20 years ago. Before their arrival, 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 opportunity, 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 car (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 obtain the best possible combustion in the cylinders.

The different triggers of a clicking or knocking noise caused by the injectors of your Kia E Niro

Experiencing injector noises on your Kia E Niro may result from different sources, we will now focus on the potential causes 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 implemented to eliminate them. If you perceive another clicking noise but it is not from your injectors, we recommend you to examine this content about clicking noise on Kia E Niro to locate the trigger.

The explanations for injector clicking or knocking noise Kia E Niro

A clicking or knocking noise from your injectors can be explained for different explanations. In fact, the injectors of your Kia E Niro 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 objective is to manage the air/fuel dosage and at last the homogeneity of the mixture, always with the target of improving combustion. If one of these three attributes 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 because of bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will induce thoses knocking or clicking noises on your Kia E Niro. The main trigger of these problems commonly originates from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible obstruction will inevitably lead to a malfunction of the injector. If after verifying, this noise originates from another component of the engine of your Kia E Niro, check this content for more informations.

The end result of injector noise on Kia E Niro

Now that we have reviewed the diverse reasons for injector noise on your Kia E Niro, we will end by stating the possible end result of malfunctioning one or more of your injectors. Whether only one is blocked, or damaged, or your entire fuel rail is involved, you cannot escape these repercussions which can fairly quickly become severe….
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 repercussions noticed by drivers is a noticeable loss of power. In fact, if your engine is running on 3 out of 4 cylinders for example, you will surely have a loss of power
Finally, you risk degrading one of your pistons or your engine. Poor combustion will fairly quickly harm your cylinders or pistons and your engine may tighten.
Here are three little suggestions 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>
