It is hardly ever pleasant to acknowledge an injector noise on your Mercedes C class. It is a noise that happens regularly, usually when you accelerate or your engine is idling. However, this sign may be connected to different sort of problems with your car injectors. It may not be anything severe, but when a persistent noise comes out, you have to be sure. Specifically since repairing your Mercedes C class’s injectors can be expensive. That’s why our team decided to compose this article content in order to help you see more clearly, learn about the different plausible failures and identify your trouble. To do this, we will first look at the normal function and usefulness of the injectors in your Mercedes C class, then at the plausible triggers from which an injector noise may come.
Benefits of the injectors
Injectors are a very useful 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 used, 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 received 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 get the best possible combustion in the cylinders.
The different causes of a clicking or knocking noise based on the injectors of your Mercedes C class
Hearing injector noises on your Mercedes C class may result from different origins, we will now concentrate 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 origins of these noises and the solutions to be put into practice to eliminate them. If you acknowledge another clicking noise but it is not from your injectors, we advise you to browse this article content about clicking noise on Mercedes C class to find the cause.
The explanations for injector clicking or knocking noise Mercedes C class
A clicking or knocking noise from your injectors can be justified by different explanations. In fact, the injectors of your Mercedes C class 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 task is to manage the air/fuel dosage and finally the homogeneity of the mixture, always with the goal of improving combustion. If one of these three tasks is altered, 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 because 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 C class. The main cause of these situations commonly 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 in a malfunction of the injector.

The repercussions of injector noise on Mercedes C class
Now that we have reviewed the several causes for injector noise on your Mercedes C class, we will end by stating the possible end result 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 side effects which can fairly quickly 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 degrading one of your pistons or your engine. Poor combustion will fairly quickly 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 changing your diesel fuel filter regularly>
