It is hardly ever pleasurable to experience an injector noise on your Volkswagen Eos. It is a noise that arises regularly, usually when you accelerate or your engine is idling. However, this warning sign may be connected to multiple kind of problems with your vehicle injectors. It may not be anything major, but when a persistent noise comes out, you have to be sure. Especially since fixing your Volkswagen Eos’s injectors can be costly. That’s why our team decided to produce this content page in order to help you see more clearly, learn about the different possible failures and establish your trouble. To do this, we will first look at the normal function and usefulness of the injectors in your Volkswagen Eos, then at the possible reasons from which an injector noise may come.
Attributes of the injectors
Injectors are a very useful part 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 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 obtained from the various sensors equipping the vehicle (engine temperature, acceleration level, engine speed, etc.). Their aim 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 origins of a clicking or knocking noise based on the injectors of your Volkswagen Eos
Hearing injector noises on your Volkswagen Eos may result from different locations, we will now focus on the potential causes of these. In most cases, the regular noise of a faulty injector is of the snap type. Here are the several origins of these noises and the solutions to be implemented to get rid of them. If you experience another clicking noise but it is not from your injectors, we recommend you to browse this content page about clicking noise on Volkswagen Eos to locate the cause.
The reasons for injector clicking or knocking noise Volkswagen Eos
A clicking or knocking noise from your injectors can be explained for different reasons. Indeed, the injectors of your Volkswagen Eos have three main tasks, to control the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to ease 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 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 as a consequence of bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will provoke thoses knocking or clicking noises on your Volkswagen Eos. The main cause of these trouble generally comes from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible obstruction will inevitably end up in a malfunction of the injector. If after verifying, this noise comes from another component of the engine of your Volkswagen Eos, browse this content page for more infos.
The effects of injector noise on Volkswagen Eos
Now that we have analyzed the diverse reasons for injector noise on your Volkswagen Eos, we will end by stating the possible end result 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 consequences 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 regular effects experienced by drivers is a distinctive loss of power. Indeed, if your engine is running on 3 out of 4 cylinders for example, you will obviously have a loss of power
Finally, you risk degrading 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 tips to limit the risks connected to 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>
