It is never enjoyable to perceive an injector noise on your Mercedes Classe Cls. It is a noise that comes up frequently, usually when you accelerate or your engine is idling. However, this sign may be connected to several kind of trouble with your automobile injectors. It may not be anything major, but when a recurrent noise comes out, you have to be sure. Especially since fixing your Mercedes Classe Cls’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 conceivable failures and establish your problem. To do this, we will first look at the normal functioning and usefulness of the injectors in your Mercedes Classe Cls, then at the conceivable reasons from which an injector noise may come.
Attributes of the injectors
Injectors are a very vital element of the operation of your engine motor. They were introduced 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 accurately (quantity of fuel injected, air/fuel mixture) via the analysis of the data collected from the various sensors equipping the automobile (engine temperature, acceleration level, engine speed, etc.). Their objective 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 based on the injectors of your Mercedes Classe Cls
Hearing injector noises on your Mercedes Classe Cls may come from different origins, we will now look into the potential causes of these. In general, the usual noise of a faulty injector is of the snap type. Here are the different sources of these noises and the solutions to be applied to prevent them. If you perceive another clicking noise but it is not from your injectors, we advise you to read this content page about clicking noise on Mercedes Classe Cls to discover the cause.
The reasons for injector clicking or knocking noise Mercedes Classe Cls
A clicking or knocking noise from your injectors can be explained for different reasons. In fact, the injectors of your Mercedes Classe Cls have three main missions, to manage the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to ease its combustion. Then, its goal is to deal with the air/fuel dosage and finally the homogeneity of the mixture, always with the aim of improving combustion. If one of these three characteristics is modified, the main purpose 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 induce thoses knocking or clicking noises on your Mercedes Classe Cls. The main cause of these problems commonly originates from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible blockage will inevitably produce a malfunction of the injector.

The repercussions of injector noise on Mercedes Classe Cls
Now that we have reviewed the diverse reasons for injector noise on your Mercedes Classe Cls, we will end by stating the possible end result of malfunctioning one or more of your injectors. Whether only one is obstructed, or damaged, or your entire fuel rail is involved, you cannot escape these effects which can promptly 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 known effects experienced by drivers is a distinctive loss of power. In fact, if your engine is running on 3 out of 4 cylinders for example, you will surely 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 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>
