It is hardly ever enjoyable to listen to an injector noise on your Kia Picanto 3. It is a noise that comes up frequently, usually when you accelerate or your engine is idling. However, this indicator may be linked to different kind of trouble with your vehicle injectors. It may not be anything severe, but when a frequent noise comes out, you have to be sure. Most importantly since replacing your Kia Picanto 3’s injectors can be costly. That’s why our team decided to compose this content in order to help you see more clearly, learn about the different plausible failures and determine your problem. To do this, we will first look at the normal functioning and usefulness of the injectors in your Kia Picanto 3, then at the plausible triggers from which an injector noise may come.
Benefits of the injectors
Injectors are a very useful component of the operation of your engine motor. They were introduced to the modern vehicles 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 ability, 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 compiled from the various sensors equipping the vehicle (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 triggers of a clicking or knocking noise coming from the injectors of your Kia Picanto 3
Listening injector noises on your Kia Picanto 3 may come from different sources, we will now focus on the potential triggers of these. In general, the typical noise of a faulty injector is of the snap type. Here are the different sources of these noises and the solutions to be implemented to stop them. If you listen to another clicking noise but it is not from your injectors, we advise you to go through this content about clicking noise on Kia Picanto 3 to locate the trigger.
The causes for injector clicking or knocking noise Kia Picanto 3
A clicking or knocking noise from your injectors can be explained for different causes. In fact, the injectors of your Kia Picanto 3 have three main tasks, to control the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to ease its combustion. Then, its task 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 characteristics is altered, the main role 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 provoke thoses knocking or clicking noises on your Kia Picanto 3. The main trigger 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 blockage will inevitably cause a malfunction of the injector.

The consequences of injector noise on Kia Picanto 3
Now that we have examined the several reasons for injector noise on your Kia Picanto 3, we will end by stating the possible end result of malfunctioning one or more of your injectors. Whether only one is clogged, or broken, or your entire fuel rail is involved, you cannot escape these effects which can almost instantly 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 known effects felt by drivers is a significant 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 almost instantly damage your cylinders or pistons and your engine may tighten.
Here are three little tips to limit the risks connected 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 changing your diesel fuel filter regularly>
