It is hardly ever relaxing to listen to an injector noise on your hyundai i20. It is a noise that comes up repeatedly, usually when you accelerate or your engine is idling. However, this sign may be relating to different types of trouble with your automobile injectors. It may not be anything severe, but when a repeated noise comes out, you have to be sure. Especially since repairing your hyundai i20’s injectors can be expensive. That’s why our team chose to compose this article content in order to help you see more clearly, learn about the different plausible failures and identify your issue. To do this, we will first look at the normal running and usefulness of the injectors in your hyundai i20, then at the plausible causes from which an injector noise may come.
Attributes of the injectors
Injectors are a very useful part of the operation of your engine unit. They were released to the modern cars 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 compiled from the various sensors equipping the automobile (engine temperature, acceleration level, engine speed, etc.). Their goal 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 triggers of a clicking or knocking noise caused by the injectors of your hyundai i20
Discovering injector noises on your hyundai i20 may come from different locations, we will now center on the potential triggers of these. In most cases, the common noise of a faulty injector is of the snap type. Here are the several origins of these noises and the solutions to be used to eliminate them. If you listen to another clicking noise but it is not from your injectors, we suggest you to go through this article content about clicking noise on hyundai i20 to locate the trigger.
The explanations for injector clicking or knocking noise hyundai i20
A clicking or knocking noise from your injectors can be explained for different explanations. Indeed, the injectors of your hyundai i20 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 control the air/fuel dosage and at last the homogeneity of the mixture, always with the aim 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 due to bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will trigger thoses knocking or clicking noises on your hyundai i20. The main trigger of these problems 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. If after verifying, this noise comes from another part of the engine of your hyundai i20, read this article content for more infos.
The side effects of injector noise on hyundai i20
Now that we have analyzed the several reasons for injector noise on your hyundai i20, we will end by stating the possible side effects 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 side effects which can quickly 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 known consequences 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 surely have a loss of power
Finally, you risk deteriorating one of your pistons or your engine. Poor combustion will quickly damage 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 swapping your diesel fuel filter regularly>
