Especially since fixing your hyundai i40’s injectors can be expensive. That’s why our team chose to compose this content page in order to support you see more clearly, learn about the different conceivable failures and identify your trouble. To do this, we will first look at the normal functioning and usefulness of the injectors in your hyundai i40, then at the conceivable triggers from which an injector noise may come.injector-noise-hyundai-i40

Benefits of the injectors

Injectors are a very important component of the operation of your engine motor. They were brought in to the modern automobiles about 20 years ago. Before their introduction, 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 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 compiled from the various sensors equipping the automobile (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 get the best possible combustion in the cylinders.

The different reasons of a clicking or knocking noise caused by the injectors of your hyundai i40

Finding out injector noises on your hyundai i40 may come from different origins, we will now center on the potential triggers of these. In general, the regular noise of a faulty injector is of the snap type. Here are the different origins of these noises and the solutions to be implemented to prevent them. If you experience another clicking noise but it is not from your injectors, we recommend you to go through this content page about clicking noise on hyundai i40 to find the reason.

The explanations for injector clicking or knocking noise hyundai i40

A clicking or knocking noise from your injectors can be justified by different explanations. In fact, the injectors of your hyundai i40 have three main tasks, to manage the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to facilitate its combustion. Then, its goal is to deal with the air/fuel dosage and finally the homogeneity of the mixture, always with the aim of improving combustion. If one of these three characteristics 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 because of bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will induce thoses knocking or clicking noises on your hyundai i40. The main reason of these trouble in most cases originates from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible blockage will inevitably cause a malfunction of the injector. If after verifying, this noise originates from another element of the engine of your hyundai i40, read this content page for more informations.

The side effects of injector noise on hyundai i40

Now that we have reviewed the several causes for injector noise on your hyundai i40, we will end by stating the possible consequences of malfunctioning one or more of your injectors. Whether only one is obstructed, or damaged, or your entire fuel rail is involved, you cannot escape these repercussions which can fairly quickly 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 common 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 surely have a loss of power
Finally, you risk degrading one of your pistons or your engine. Poor combustion will fairly quickly 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>
