To do this, we will first look at the normal function and usefulness of the injectors in your Mercedes AMG GT, then at the conceivable reasons from which an injector noise may come.injector-noise-mercedes-amg-gt

Benefits of the injectors

Injectors are a very vital part of the operation of your engine motor. They were brought in 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 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 obtained from the various sensors equipping the car (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 triggers of a clicking or knocking noise caused by the injectors of your Mercedes AMG GT

Hearing injector noises on your Mercedes AMG GT may come from different origins, we will now concentrate 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 prevent them. If you listen to another clicking noise but it is not from your injectors, we recommend you to browse this article about clicking noise on Mercedes AMG GT to locate the cause.

The explanations for injector clicking or knocking noise Mercedes AMG GT

A clicking or knocking noise from your injectors can be explained for different explanations. In fact, the injectors of your Mercedes AMG GT 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 finally the homogeneity of the mixture, always with the objective of improving combustion. If one of these three features 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 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 Mercedes AMG GT. The main cause of these concerns 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 end up in a malfunction of the injector. If after verifying, this noise comes from another element of the engine of your Mercedes AMG GT, have a look at this article for more infos.

The consequences of injector noise on Mercedes AMG GT

Now that we have reviewed the different causes for injector noise on your Mercedes AMG GT, we will end by stating the possible consequences of malfunctioning one or more of your injectors. Whether only one is blocked, or damaged, or your entire fuel rail is involved, you cannot escape these effects which can almost instantly become major….
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 basic effects experienced by drivers is a noticeable loss of power. In fact, if your engine is running on 3 out of 4 cylinders for example, you will undoubtedly have a loss of power
Finally, you risk degrading 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 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 swapping your diesel fuel filter regularly>
