It is never pleasant to perceive an injector noise on your Hyundai Sonata. It is a noise that arises repeatedly, usually when you accelerate or your engine is idling. However, this sign may be linked to several sort of complications with your automobile injectors. It may not be anything major, but when a recurrent noise shows up, you have to be sure. Specifically since replacing your Hyundai Sonata’s injectors can be expensive. That’s why our team decided to write this content in order to help you see more clearly, learn about the different conceivable failures and identify your issue. To do this, we will first look at the normal function and usefulness of the injectors in your Hyundai Sonata, then at the conceivable causes from which an injector noise may come.injector-noise-hyundai-sonata

Purposes of the injectors

Injectors are a very important element of the operation of your engine. They were brought in 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 collected 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 Hyundai Sonata

Finding out injector noises on your Hyundai Sonata may result from different origins, we will now look into the potential causes of these. In most cases, the usual noise of a faulty injector is of the snap type. Here are the different sources of these noises and the solutions to be used to eliminate them. If you perceive another clicking noise but it is not from your injectors, we advise you to go through this content about clicking noise on Hyundai Sonata to locate the cause.

The causes for injector clicking or knocking noise Hyundai Sonata

A clicking or knocking noise from your injectors can be explained for different causes. Indeed, the injectors of your Hyundai Sonata have three main tasks, to manage 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 at last the homogeneity of the mixture, always with the target of improving combustion. If one of these three attributes 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 induce thoses knocking or clicking noises on your Hyundai Sonata. The main cause of these problems usually originates from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible blockage will inevitably result in a malfunction of the injector.

The end result of injector noise on Hyundai Sonata

Now that we have examined the several reasons for injector noise on your Hyundai Sonata, 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 repercussions which can promptly become serious….
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 repercussions experienced by drivers is a noticeable loss of power. Indeed, if your engine is running on 3 out of 4 cylinders for example, you will surely have a loss of power
Finally, you risk degrading 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 suggestions to limit the risks associated 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 swapping your diesel fuel filter regularly>
