It is hardly ever pleasant to listen to an injector noise on your Bmw Serie 3 F30. It is a noise that comes up regularly, usually when you accelerate or your engine is idling. However, this indication may be linked to different sort of complications with your vehicle injectors. It may not be anything serious, but when a recurrent noise arises, you have to be sure. Most importantly since fixing your Bmw Serie 3 F30’s injectors can be costly. That’s why our team decided to write this content page in order to help you see more clearly, learn about the different possible failures and distinguish your trouble. To do this, we will first look at the normal functioning and usefulness of the injectors in your Bmw Serie 3 F30, then at the possible triggers from which an injector noise may come.
Purposes of the injectors
Injectors are a very significant element 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 precisely (quantity of fuel injected, air/fuel mixture) via the analysis of the data received from the various sensors equipping the vehicle (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 reasons of a clicking or knocking noise based on the injectors of your Bmw Serie 3 F30
Discovering injector noises on your Bmw Serie 3 F30 may result from different origins, we will now look into the potential triggers of these. Generally, the usual noise of a faulty injector is of the snap type. Here are the several origins of these noises and the solutions to be implemented to get rid of them. If you listen to another clicking noise but it is not from your injectors, we recommend you to read this content page about clicking noise on Bmw Serie 3 F30 to discover the trigger.
The reasons for injector clicking or knocking noise Bmw Serie 3 F30
A clicking or knocking noise from your injectors can be justified by different reasons. In fact, the injectors of your Bmw Serie 3 F30 have three main missions, to manage the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to ease its combustion. Then, its mission is to deal with 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 altered, the main purpose of the injectors will be disturbed 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 trigger thoses knocking or clicking noises on your Bmw Serie 3 F30. The main trigger of these trouble commonly originates from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible blockage will inevitably lead to a malfunction of the injector. If after verifying, this noise originates from another component of the engine of your Bmw Serie 3 F30, have a look at this content page for more informations.
The side effects of injector noise on Bmw Serie 3 F30
Now that we have examined the several reasons for injector noise on your Bmw Serie 3 F30, we will end by stating the possible end result of malfunctioning one or more of your injectors. Whether only one is clogged, or broken, or your entire fuel rail is involved, you cannot escape these side effects which can 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 repercussions experienced by drivers is a severe 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 quickly affect your cylinders or pistons and your engine may tighten.
Here are three little recommendations to limit the risks connected 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>
