It is hardly ever pleasant to perceive an injector noise on your Bmw Serie 2 F22. It is a noise that appears repeatedly, usually when you accelerate or your engine is idling. However, this sign may be related to different types of concerns with your automobile injectors. It may not be anything major, but when a frequent noise shows up, you have to be sure. Specifically since repairing your Bmw Serie 2 F22’s injectors can be costly. That’s why our team chose to compose this article content in order to help you see more clearly, learn about the different conceivable failures and establish your trouble. To do this, we will first look at the normal running and usefulness of the injectors in your Bmw Serie 2 F22, then at the conceivable causes from which an injector noise may come.
Purposes of the injectors
Injectors are a very important element of the operation of your engine motor. They were introduced to the modern cars 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 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 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 get the best possible combustion in the cylinders.
The different causes of a clicking or knocking noise coming from the injectors of your Bmw Serie 2 F22
Listening injector noises on your Bmw Serie 2 F22 may result from different locations, we will now look into the potential causes of these. In general, 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 eliminate them. If you perceive another clicking noise but it is not from your injectors, we suggest you to browse this article content about clicking noise on Bmw Serie 2 F22 to locate the trigger.
The explanations for injector clicking or knocking noise Bmw Serie 2 F22
A clicking or knocking noise from your injectors can be justified by different explanations. In fact, the injectors of your Bmw Serie 2 F22 have three main tasks, to control the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to facilitate its combustion. Then, its mission is to control the air/fuel dosage and at last the homogeneity of the mixture, always with the goal of improving combustion. If one of these three characteristics is modified, 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 induce thoses knocking or clicking noises on your Bmw Serie 2 F22. The main trigger of these situations in most cases comes from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible obstruction will inevitably result in a malfunction of the injector.

The consequences of injector noise on Bmw Serie 2 F22
Now that we have analyzed the diverse reasons for injector noise on your Bmw Serie 2 F22, we will end by stating the possible side effects 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 major….
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 regular consequences experienced 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 degrading one of your pistons or your engine. Poor combustion will quickly damage 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 changing your diesel fuel filter regularly>
