It is rarely ever relaxing to listen an injector noise on your Mercedes Benz GLS Class. It is a noise that happens repeatedly, usually when you accelerate or your engine is idling. However, this warning sign may be related to different sort of problems with your automobile injectors. It may not be anything severe, but when a continuing noise shows up, you have to be sure. Most importantly since replacing your Mercedes Benz GLS Class’s injectors can be costly. That’s why our team chose to create this article in order to help you see more clearly, learn about the different plausible failures and determine your issue. To do this, we will first look at the normal functioning and usefulness of the injectors in your Mercedes Benz GLS Class, then at the plausible reasons from which an injector noise may come.
Functions of the injectors
Injectors are a very useful part of the operation of your engine. 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 possibility, 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 automobile (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 obtain the best possible combustion in the cylinders.
The different reasons of a clicking or knocking noise coming from the injectors of your Mercedes Benz GLS Class
Experiencing injector noises on your Mercedes Benz GLS Class may result from different origins, we will now center on the potential triggers of these. In most cases, the common noise of a faulty injector is of the snap type. Here are the different origins of these noises and the solutions to be adopted to stop them. If you listen another clicking noise but it is not from your injectors, we suggest you to examine this article about clicking noise on Mercedes Benz GLS Class to discover the trigger.
The causes for injector clicking or knocking noise Mercedes Benz GLS Class
A clicking or knocking noise from your injectors can be justified by different causes. In fact, the injectors of your Mercedes Benz GLS Class have three main missions, to manage the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to facilitate 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 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 trigger thoses knocking or clicking noises on your Mercedes Benz GLS Class. The main trigger of these situations commonly originates from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible obstruction will inevitably produce a malfunction of the injector. If after checking, this noise originates from another component of the engine of your Mercedes Benz GLS Class, have a look at this article for more informations.
The consequences of injector noise on Mercedes Benz GLS Class
Now that we have analyzed the several causes for injector noise on your Mercedes Benz GLS Class, we will end by stating the possible consequences 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 effects which can fairly quickly 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 common repercussions noticed by drivers is a noticeable 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 fairly quickly affect 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>
