It is hardly ever pleasurable to acknowledge an injector noise on your Audi Tt. It is a noise that appears frequently, usually when you accelerate or your engine is idling. However, this indication may be connected to different types of complications with your automobile injectors. It may not be anything serious, but when a continuing noise arises, you have to be sure. Most importantly since replacing your Audi Tt’s injectors can be costly. That’s why our team chose to compose this content in order to support you see more clearly, learn about the different plausible failures and establish your trouble. To do this, we will first look at the normal function and usefulness of the injectors in your Audi Tt, then at the plausible causes from which an injector noise may come.
Purposes of the injectors
Injectors are a very important part of the operation of your engine. They were released to the modern vehicles 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 obtained from the various sensors equipping the automobile (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 causes of a clicking or knocking noise caused by the injectors of your Audi Tt
Discovering injector noises on your Audi Tt may originate 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 different sources of these noises and the solutions to be adopted to eliminate them. If you acknowledge another clicking noise but it is not from your injectors, we suggest you to browse this content about clicking noise on Audi Tt to discover the trigger.
The reasons for injector clicking or knocking noise Audi Tt
A clicking or knocking noise from your injectors can be justified by different reasons. In fact, the injectors of your Audi Tt have three main tasks, to control the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to ease its combustion. Then, its goal 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 resulting from bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will trigger thoses knocking or clicking noises on your Audi Tt. The main trigger of these situations usually 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 component of the engine of your Audi Tt, have a look at this content for more infos.
The end result of injector noise on Audi Tt
Now that we have examined the several reasons for injector noise on your Audi Tt, we will end by stating the possible consequences 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 almost instantly become critical….
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 common effects noticed by drivers is a significant loss of power. In fact, if your engine is running on 3 out of 4 cylinders for example, you will obviously have a loss of power
Finally, you risk deteriorating one of your pistons or your engine. Poor combustion will almost instantly harm your cylinders or pistons and your engine may tighten.
Here are three little tips 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>
