It is hardly ever pleasant to notice an injector noise on your Kia Rio. It is a noise that arises repeatedly, usually when you accelerate or your engine is idling. However, this symptom may be connected to different sort of trouble with your automobile injectors. It may not be anything major, but when a frequent noise comes out, you have to be sure. Specifically since repairing your Kia Rio’s injectors can be expensive. That’s why our team chose to create this article content in order to help you see more clearly, learn about the different conceivable failures and determine your issue. To do this, we will first look at the normal functioning and usefulness of the injectors in your Kia Rio, then at the conceivable triggers from which an injector noise may come.injector-noise-kia-rio

Benefits of the injectors

Injectors are a very useful part of the operation of your engine motor. They were launched to the modern cars about 20 years ago. Before their appearance, 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 precisely (quantity of fuel injected, air/fuel mixture) via the analysis of the data collected from the various sensors equipping the automobile (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 get the best possible combustion in the cylinders.

The different triggers of a clicking or knocking noise coming from the injectors of your Kia Rio

Hearing injector noises on your Kia Rio may originate from different origins, we will now center on the potential triggers of these. Generally, the regular noise of a faulty injector is of the snap type. Here are the different sources of these noises and the solutions to be applied to prevent them. If you notice another clicking noise but it is not from your injectors, we encourage you to browse this article content about clicking noise on Kia Rio to discover the reason.

The explanations for injector clicking or knocking noise Kia Rio

A clicking or knocking noise from your injectors can be justified by different explanations. In fact, the injectors of your Kia Rio have three main tasks, to control the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to facilitate its combustion. Then, its goal is to control the air/fuel dosage and finally the homogeneity of the mixture, always with the objective of improving combustion. If one of these three attributes is modified, the main functionality 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 trigger thoses knocking or clicking noises on your Kia Rio. The main reason of these problems in most cases originates from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible blockage will inevitably end in a malfunction of the injector.

The end result of injector noise on Kia Rio

Now that we have examined the diverse reasons for injector noise on your Kia Rio, we will end by stating the possible side effects of malfunctioning one or more of your injectors. Whether only one is blocked, or broken, or your entire fuel rail is involved, you cannot escape these consequences which can almost instantly become critical….
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 regular consequences experienced 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 obviously have a loss of power
Finally, you risk degrading one of your pistons or your engine. Poor combustion will almost instantly damage your cylinders or pistons and your engine may tighten.
Here are three little tips to limit the risks connected 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 swapping your diesel fuel filter regularly>
