It is hardly ever pleasurable to listen to an injector noise on your Mercedes Classe Glc. It is a noise that happens continually, usually when you accelerate or your engine is idling. However, this warning sign may be relating to several sort of concerns with your car injectors. It may not be anything severe, but when a frequent noise shows up, you have to be sure. Most importantly since replacing your Mercedes Classe Glc’s injectors can be costly. That’s why our team decided to prepare this content 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 running and usefulness of the injectors in your Mercedes Classe Glc, then at the possible causes from which an injector noise may come.injector-noise-mercedes-classe-glc

Purposes of the injectors

Injectors are a very vital part of the operation of your engine. They were released to the modern automobiles about 20 years ago. Before their arrival, 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 precisely (quantity of fuel injected, air/fuel mixture) via the analysis of the data compiled from the various sensors equipping the car (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 origins of a clicking or knocking noise based on the injectors of your Mercedes Classe Glc

Experiencing injector noises on your Mercedes Classe Glc may originate from different locations, we will now concentrate on the potential causes of these. Generally, the common noise of a faulty injector is of the snap type. Here are the several sources of these noises and the solutions to be put into practice to eliminate them. If you listen to another clicking noise but it is not from your injectors, we suggest you to read this content about clicking noise on Mercedes Classe Glc to locate the reason.

The explanations for injector clicking or knocking noise Mercedes Classe Glc

A clicking or knocking noise from your injectors can be explained for different explanations. In fact, the injectors of your Mercedes Classe Glc have three main missions, to manage the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to ease its combustion. Then, its objective is to control the air/fuel dosage and at last the homogeneity of the mixture, always with the goal of improving combustion. If one of these three characteristics is altered, the main functionality of the injectors will be disturbed 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 Mercedes Classe Glc. The main reason of these situations usually comes from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible blockage will inevitably end up in a malfunction of the injector. If after checking, this noise comes from another part of the engine of your Mercedes Classe Glc, check this content for more informations.

The consequences of injector noise on Mercedes Classe Glc

Now that we have reviewed the different causes for injector noise on your Mercedes Classe Glc, we will end by stating the possible side effects of malfunctioning one or more of your injectors. Whether only one is clogged, or damaged, or your entire fuel rail is involved, you cannot escape these consequences which can almost instantly become critical….
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 felt by drivers is a serious 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 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 suggestions 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>
