It is hardly ever pleasant to listen an injector noise on your Kia Picanto. It is a noise that happens frequently, usually when you accelerate or your engine is idling. However, this sign may be connected to several kind of concerns with your automobile injectors. It may not be anything severe, but when a continuing noise appears, you have to be sure. Most importantly since replacing your Kia Picanto’s injectors can be expensive. That’s why our team chose to create this article content in order to support you see more clearly, learn about the different plausible failures and identify your problem. To do this, we will first look at the normal running and usefulness of the injectors in your Kia Picanto, then at the plausible causes from which an injector noise may come.injector-noise-kia-picanto

Purposes of the injectors

Injectors are a very fundamental part of the operation of your engine unit. They were introduced to the modern vehicles 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 ability, 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 compiled from the various sensors equipping the automobile (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 get the best possible combustion in the cylinders.

The different origins of a clicking or knocking noise coming from the injectors of your Kia Picanto

Finding out injector noises on your Kia Picanto may originate from different sources, we will now look into the potential causes of these. In most cases, the regular noise of a faulty injector is of the snap type. Here are the different origins of these noises and the solutions to be adopted to prevent them. If you listen another clicking noise but it is not from your injectors, we suggest you to browse this article content about clicking noise on Kia Picanto to locate the cause.

The reasons for injector clicking or knocking noise Kia Picanto

A clicking or knocking noise from your injectors can be justified by different reasons. In fact, the injectors of your Kia Picanto have three main tasks, to manage the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to facilitate its combustion. Then, its mission is to manage the air/fuel dosage and finally the homogeneity of the mixture, always with the goal of improving combustion. If one of these three features is altered, the main functionality of the injectors will be disturbed and this will lead to poor combustion. This bad combustion will be a violent explosion in the cylinders due to bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will induce thoses knocking or clicking noises on your Kia Picanto. The main cause of these concerns commonly originates 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. If after verifying, this noise originates from another element of the engine of your Kia Picanto, check this article content for more informations.

The end result of injector noise on Kia Picanto

Now that we have examined the several causes for injector noise on your Kia Picanto, 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 quickly become considerable….
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 common effects 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 inevitably have a loss of power
Finally, you risk degrading 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 tips 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>
