It is never relaxing to acknowledge an injector noise on your Bmw Serie 6. It is a noise that appears repeatedly, usually when you accelerate or your engine is idling. However, this symptom may be linked to multiple sort of concerns with your car injectors. It may not be anything major, but when a recurrent noise comes out, you have to be sure. Especially since repairing your Bmw Serie 6’s injectors can be expensive. That’s why our team decided to compose this content in order to support you see more clearly, learn about the different conceivable failures and identify your trouble. To do this, we will first look at the normal functioning and usefulness of the injectors in your Bmw Serie 6, then at the conceivable reasons from which an injector noise may come.
Functions of the injectors
Injectors are a very important part of the operation of your engine unit. They were released to the modern automobiles about 20 years ago. Before their appearance, 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 compiled 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 causes of a clicking or knocking noise based on the injectors of your Bmw Serie 6
Discovering injector noises on your Bmw Serie 6 may come from different sources, we will now concentrate on the potential causes of these. In general, the typical 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 recommend you to browse this content about clicking noise on Bmw Serie 6 to locate the cause.
The causes for injector clicking or knocking noise Bmw Serie 6
A clicking or knocking noise from your injectors can be justified by different causes. Indeed, the injectors of your Bmw Serie 6 have three main missions, to manage the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to facilitate its combustion. Then, its objective is to manage the air/fuel dosage and at last the homogeneity of the mixture, always with the objective 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 due to bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will provoke thoses knocking or clicking noises on your Bmw Serie 6. The main cause of these problems commonly comes from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible obstruction will inevitably cause a malfunction of the injector. If after verifying, this noise comes from another part of the engine of your Bmw Serie 6, read this content for more informations.
The repercussions of injector noise on Bmw Serie 6
Now that we have examined the different reasons for injector noise on your Bmw Serie 6, we will end by stating the possible end result 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 repercussions which can almost instantly 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 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 obviously have a loss of power
Finally, you risk deteriorating one of your pistons or your engine. Poor combustion will almost instantly affect your cylinders or pistons and your engine may tighten.
Here are three little recommendations 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 changing your diesel fuel filter regularly>
