It is rarely ever relaxing to perceive an injector noise on your Hyundai Veloster. It is a noise that arises frequently, usually when you accelerate or your engine is idling. However, this indicator may be connected to several types of concerns with your car injectors. It may not be anything serious, but when a persistent noise appears, you have to be sure. Most importantly since replacing your Hyundai Veloster’s injectors can be costly. That’s why our team chose to create this article in order to help you see more clearly, learn about the different possible failures and identify your issue. To do this, we will first look at the normal running and usefulness of the injectors in your Hyundai Veloster, then at the possible triggers from which an injector noise may come.injector-noise-hyundai-veloster

Attributes of the injectors

Injectors are a very vital component of the operation of your engine. They were released to the modern automobiles 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 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 received from the various sensors equipping the car (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 based on the injectors of your Hyundai Veloster

Finding out injector noises on your Hyundai Veloster may come from different origins, we will now concentrate on the potential causes 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 adopted to stop them. If you perceive another clicking noise but it is not from your injectors, we encourage you to examine this article about clicking noise on Hyundai Veloster to discover the reason.

The causes for injector clicking or knocking noise Hyundai Veloster

A clicking or knocking noise from your injectors can be justified by different causes. In fact, the injectors of your Hyundai Veloster 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 mission is to control the air/fuel dosage and finally the homogeneity of the mixture, always with the target of improving combustion. If one of these three characteristics 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 as a consequence of bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will trigger thoses knocking or clicking noises on your Hyundai Veloster. The main reason 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.

The consequences of injector noise on Hyundai Veloster

Now that we have reviewed the different causes for injector noise on your Hyundai Veloster, we will end by stating the possible end result 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 effects which can almost instantly become severe….
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 basic consequences felt by drivers is a distinctive 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 deteriorating one of your pistons or your engine. Poor combustion will almost instantly harm your cylinders or pistons and your engine may tighten.
Here are three little recommendations 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 changing your diesel fuel filter regularly>
