It is hardly ever relaxing to listen an injector noise on your Skoda Karoq. It is a noise that comes up frequently, usually when you accelerate or your engine is idling. However, this sign may be relating to different types of concerns with your automobile injectors. It may not be anything major, but when a repeated noise comes out, you have to be sure. Specifically since fixing your Skoda Karoq’s injectors can be expensive. That’s why our team decided to prepare this article in order to help you see more clearly, learn about the different possible failures and distinguish your trouble. To do this, we will first look at the normal functioning and usefulness of the injectors in your Skoda Karoq, then at the possible causes from which an injector noise may come.injector-noise-skoda-karoq

Purposes of the injectors

Injectors are a very significant element of the operation of your engine motor. They were launched to the modern cars 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 possibility, 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 obtained 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 reasons of a clicking or knocking noise caused by the injectors of your Skoda Karoq

Hearing injector noises on your Skoda Karoq may come from different sources, we will now focus on the potential triggers of these. In general, the usual noise of a faulty injector is of the snap type. Here are the different origins of these noises and the solutions to be put into practice to stop them. If you listen another clicking noise but it is not from your injectors, we suggest you to examine this article about clicking noise on Skoda Karoq to locate the reason.

The reasons for injector clicking or knocking noise Skoda Karoq

A clicking or knocking noise from your injectors can be justified by different reasons. Indeed, the injectors of your Skoda Karoq have three main missions, to manage the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to facilitate its combustion. Then, its task is to deal with the air/fuel dosage and at last the homogeneity of the mixture, always with the target of improving combustion. If one of these three features is modified, the main purpose of the injectors will be disturbed 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 provoke thoses knocking or clicking noises on your Skoda Karoq. The main reason of these situations in most cases comes 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.

The consequences of injector noise on Skoda Karoq

Now that we have examined the different reasons for injector noise on your Skoda Karoq, we will end by stating the possible 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 side effects which can almost instantly 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 known effects experienced by drivers is a significant loss of power. Indeed, 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 recommendations 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>
