It is hardly ever pleasant to hear an injector noise on your Hyundai Tucson. It is a noise that arises frequently, usually when you accelerate or your engine is idling. However, this symptom may be relating to several types of concerns with your vehicle injectors. It may not be anything severe, but when a continuing noise arises, you have to be sure. Most importantly since repairing your Hyundai Tucson’s injectors can be costly. That’s why our team decided to compose this article content in order to help you see more clearly, learn about the different possible failures and distinguish your problem. To do this, we will first look at the normal function and usefulness of the injectors in your Hyundai Tucson, then at the possible triggers from which an injector noise may come.
Benefits of the injectors
Injectors are a very important component of the operation of your engine. They were released to the modern vehicles about 20 years ago. Before their introduction, 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 possibility, 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 vehicle (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 get the best possible combustion in the cylinders.
The different origins of a clicking or knocking noise coming from the injectors of your Hyundai Tucson
Discovering injector noises on your Hyundai Tucson may come from different locations, we will now concentrate on the potential causes of these. In general, the usual 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 eliminate them. If you hear another clicking noise but it is not from your injectors, we encourage you to go through this article content about clicking noise on Hyundai Tucson to discover the cause.
The explanations for injector clicking or knocking noise Hyundai Tucson
A clicking or knocking noise from your injectors can be explained for different explanations. Indeed, the injectors of your Hyundai Tucson have three main tasks, to control the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to facilitate its combustion. Then, its mission is to control the air/fuel dosage and at last the homogeneity of the mixture, always with the objective of improving combustion. If one of these three characteristics is altered, the main purpose of the injectors will be disrupted 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 Tucson. The main cause of these situations in most cases comes from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible obstruction will inevitably result in a malfunction of the injector. If after verifying, this noise comes from another element of the engine of your Hyundai Tucson, have a look at this article content for more infos.
The effects of injector noise on Hyundai Tucson
Now that we have examined the different reasons for injector noise on your Hyundai Tucson, 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 effects which can promptly become considerable….
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 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 inevitably have a loss of power
Finally, you risk degrading one of your pistons or your engine. Poor combustion will promptly affect your cylinders or pistons and your engine may tighten.
Here are three little recommendations 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 changing your diesel fuel filter regularly>
