It is rarely ever enjoyable to listen an injector noise on your Hyundai Elantra. It is a noise that appears frequently, usually when you accelerate or your engine is idling. However, this sign may be relating to several kind of complications with your vehicle injectors. It may not be anything major, but when a persistent noise comes out, you have to be sure. Most importantly since replacing your Hyundai Elantra’s injectors can be expensive. That’s why our team chose to compose this content page in order to help you see more clearly, learn about the different conceivable failures and distinguish your trouble. To do this, we will first look at the normal function and usefulness of the injectors in your Hyundai Elantra, then at the conceivable reasons from which an injector noise may come.
Functions of the injectors
Injectors are a very useful part of the operation of your engine motor. They were introduced to the modern automobiles about 20 years ago. Before their appearance, more conventional carburettor-type intake systems were employed, 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 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 obtain the best possible combustion in the cylinders.
The different causes of a clicking or knocking noise based on the injectors of your Hyundai Elantra
Experiencing injector noises on your Hyundai Elantra may come from different sources, we will now focus on the potential triggers of these. In most cases, the typical 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 prevent them. If you listen another clicking noise but it is not from your injectors, we encourage you to examine this content page about clicking noise on Hyundai Elantra to discover the trigger.
The reasons for injector clicking or knocking noise Hyundai Elantra
A clicking or knocking noise from your injectors can be explained for different reasons. In fact, the injectors of your Hyundai Elantra have three main missions, to control the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to facilitate its combustion. Then, its goal 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 attributes 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 Elantra. The main trigger of these concerns commonly comes 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 end result of injector noise on Hyundai Elantra
Now that we have examined the diverse causes for injector noise on your Hyundai Elantra, 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 promptly become severe….
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 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 surely have a loss of power
Finally, you risk degrading one of your pistons or your engine. Poor combustion will promptly harm your cylinders or pistons and your engine may tighten.
Here are three little suggestions 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>
