It is never pleasurable to notice an injector noise on your Mercedes Benz GL Class. It is a noise that arises repeatedly, usually when you accelerate or your engine is idling. However, this warning sign may be related to several sort of problems with your automobile injectors. It may not be anything severe, but when a frequent noise arises, you have to be sure. Especially since repairing your Mercedes Benz GL Class’s injectors can be expensive. That’s why our team decided to compose this article in order to help you see more clearly, learn about the different plausible failures and establish your trouble. To do this, we will first look at the normal function and usefulness of the injectors in your Mercedes Benz GL Class, then at the plausible triggers from which an injector noise may come.
Benefits of the injectors
Injectors are a very fundamental component of the operation of your engine motor. They were introduced to the modern automobiles 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 opportunity, 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 compiled 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 coming from the injectors of your Mercedes Benz GL Class
Finding out injector noises on your Mercedes Benz GL Class may come from different origins, we will now center on the potential triggers of these. Generally, the common noise of a faulty injector is of the snap type. Here are the different sources of these noises and the solutions to be used to stop them. If you notice another clicking noise but it is not from your injectors, we advise you to read this article about clicking noise on Mercedes Benz GL Class to find the trigger.
The explanations for injector clicking or knocking noise Mercedes Benz GL Class
A clicking or knocking noise from your injectors can be justified by different explanations. Indeed, the injectors of your Mercedes Benz GL 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 objective is to control the air/fuel dosage and finally 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 disturbed 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 trigger thoses knocking or clicking noises on your Mercedes Benz GL Class. The main trigger of these concerns generally comes from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible obstruction will inevitably lead to a malfunction of the injector. If after checking, this noise comes from another element of the engine of your Mercedes Benz GL Class, check this article for more informations.
The side effects of injector noise on Mercedes Benz GL Class
Now that we have reviewed the several causes for injector noise on your Mercedes Benz GL Class, 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 fairly quickly become severe….
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 consequences felt by drivers is a distinctive loss of power. Indeed, 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 fairly quickly damage your cylinders or pistons and your engine may tighten.
Here are three little suggestions to limit the risks relating 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>
