It is hardly ever pleasant to listen to an injector noise on your Kia Carens. It is a noise that appears frequently, usually when you accelerate or your engine is idling. However, this indication may be relating to several sort of trouble with your automobile injectors. It may not be anything serious, but when a repeated noise comes out, you have to be sure. Especially since repairing your Kia Carens’s injectors can be expensive. That’s why our team chose to write this content page in order to support you see more clearly, learn about the different conceivable failures and identify your problem. To do this, we will first look at the normal running and usefulness of the injectors in your Kia Carens, then at the conceivable triggers from which an injector noise may come.injector-noise-kia-carens

Purposes of the injectors

Injectors are a very significant element of the operation of your engine motor. They were released to the modern automobiles about 20 years ago. Before their arrival, 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 received 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 obtain the best possible combustion in the cylinders.

The different reasons of a clicking or knocking noise coming from the injectors of your Kia Carens

Discovering injector noises on your Kia Carens may result from different sources, we will now concentrate on the potential triggers of these. Generally, the common 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 listen to another clicking noise but it is not from your injectors, we recommend you to browse this content page about clicking noise on Kia Carens to find the reason.

The explanations for injector clicking or knocking noise Kia Carens

A clicking or knocking noise from your injectors can be explained for different explanations. In fact, the injectors of your Kia Carens 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 task is to control the air/fuel dosage and at last the homogeneity of the mixture, always with the goal of improving combustion. If one of these three attributes 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 induce thoses knocking or clicking noises on your Kia Carens. The main reason of these problems usually comes from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible blockage will inevitably end up in a malfunction of the injector. If after checking, this noise comes from another component of the engine of your Kia Carens, have a look at this content page for more informations.

The consequences of injector noise on Kia Carens

Now that we have analyzed the diverse reasons for injector noise on your Kia Carens, we will end by stating the possible side effects 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 effects which can promptly become critical….
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 effects noticed by drivers is a serious loss of power. In fact, 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 promptly damage 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 changing your diesel fuel filter regularly>
