It is rarely ever enjoyable to notice an injector noise on your Mercedes Actros. It is a noise that appears continually, usually when you accelerate or your engine is idling. However, this symptom may be related to several sort of complications with your car injectors. It may not be anything severe, but when a recurrent noise shows up, you have to be sure. Especially since fixing your Mercedes Actros’s injectors can be expensive. That’s why our team chose to produce this content page in order to support you see more clearly, learn about the different conceivable failures and determine your problem. To do this, we will first look at the normal functioning and usefulness of the injectors in your Mercedes Actros, then at the conceivable causes from which an injector noise may come.injector-noise-mercedes-actros

Purposes of the injectors

Injectors are a very fundamental component of the operation of your engine unit. They were released to the modern vehicles 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 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 get the best possible combustion in the cylinders.

The different origins of a clicking or knocking noise caused by the injectors of your Mercedes Actros

Finding out injector noises on your Mercedes Actros may result from different locations, we will now look into the potential causes of these. Generally, 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 applied to stop them. If you notice another clicking noise but it is not from your injectors, we suggest you to read this content page about clicking noise on Mercedes Actros to discover the trigger.

The explanations for injector clicking or knocking noise Mercedes Actros

A clicking or knocking noise from your injectors can be justified by different explanations. Indeed, the injectors of your Mercedes Actros 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 objective is to deal with the air/fuel dosage and at last the homogeneity of the mixture, always with the target of improving combustion. If one of these three attributes 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 as a consequence of bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will trigger thoses knocking or clicking noises on your Mercedes Actros. The main trigger of these situations generally originates 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. If after verifying, this noise originates from another element of the engine of your Mercedes Actros, have a look at this content page for more infos.

The side effects of injector noise on Mercedes Actros

Now that we have analyzed the diverse reasons for injector noise on your Mercedes Actros, we will end by stating the possible consequences 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 repercussions which can promptly become considerable….
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 repercussions felt by drivers is a significant loss of power. Indeed, 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 promptly harm your cylinders or pistons and your engine may tighten.
Here are three little suggestions to limit the risks connected 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>
