It is never enjoyable to experience an injector noise on your Mercedes Classe B 3. It is a noise that comes up continually, usually when you accelerate or your engine is idling. However, this indicator may be related to multiple sort of trouble with your vehicle injectors. It may not be anything major, but when a repeated noise shows up, you have to be sure. Specifically since fixing your Mercedes Classe B 3’s injectors can be expensive. That’s why our team chose to create this article content in order to support you see more clearly, learn about the different conceivable failures and identify your problem. To do this, we will first look at the normal running and usefulness of the injectors in your Mercedes Classe B 3, then at the conceivable reasons from which an injector noise may come.
Purposes of the injectors
Injectors are a very important component of the operation of your engine motor. 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 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 received from the various sensors equipping the vehicle (engine temperature, acceleration level, engine speed, etc.). Their purpose 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 reasons of a clicking or knocking noise based on the injectors of your Mercedes Classe B 3
Finding out injector noises on your Mercedes Classe B 3 may come from different sources, we will now center on the potential triggers of these. In general, the typical noise of a faulty injector is of the snap type. Here are the different origins of these noises and the solutions to be used to stop them. If you experience another clicking noise but it is not from your injectors, we suggest you to read this article content about clicking noise on Mercedes Classe B 3 to locate the reason.
The causes for injector clicking or knocking noise Mercedes Classe B 3
A clicking or knocking noise from your injectors can be justified by different causes. In fact, the injectors of your Mercedes Classe B 3 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 task is to control the air/fuel dosage and finally the homogeneity of the mixture, always with the goal of improving combustion. If one of these three attributes is altered, the main functionality 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 induce thoses knocking or clicking noises on your Mercedes Classe B 3. The main reason of these problems in most cases comes from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible blockage will inevitably end in a malfunction of the injector.

The side effects of injector noise on Mercedes Classe B 3
Now that we have examined the different causes for injector noise on your Mercedes Classe B 3, we will end by stating the possible side effects 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 promptly become serious….
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 common consequences felt 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 inevitably have a loss of power
Finally, you risk degrading one of your pistons or your engine. Poor combustion will promptly damage your cylinders or pistons and your engine may tighten.
Here are three little recommendations 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>
