It is hardly ever relaxing to experience an injector noise on your Bmw Serie 1 F20. It is a noise that comes up repeatedly, usually when you accelerate or your engine is idling. However, this sign may be related to different types of trouble with your car injectors. It may not be anything serious, but when a frequent noise appears, you have to be sure. Most importantly since fixing your Bmw Serie 1 F20’s injectors can be costly. That’s why our team chose to produce this article in order to support you see more clearly, learn about the different plausible failures and establish your problem. To do this, we will first look at the normal function and usefulness of the injectors in your Bmw Serie 1 F20, then at the plausible causes from which an injector noise may come.
Functions of the injectors
Injectors are a very important component of the operation of your engine unit. They were released to the modern vehicles about 20 years ago. Before their arrival, 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 accumulated from the various sensors equipping the car (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 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 1 F20
Finding out injector noises on your Bmw Serie 1 F20 may originate from different sources, we will now concentrate on the potential causes of these. Generally, the typical 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 stop them. If you experience another clicking noise but it is not from your injectors, we recommend you to browse this article about clicking noise on Bmw Serie 1 F20 to find the cause.
The reasons for injector clicking or knocking noise Bmw Serie 1 F20
A clicking or knocking noise from your injectors can be explained for different reasons. In fact, the injectors of your Bmw Serie 1 F20 have three main tasks, to manage the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to facilitate its combustion. Then, its objective is to deal with the air/fuel dosage and at last the homogeneity of the mixture, always with the aim of improving combustion. If one of these three functions is modified, the main functionality 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 provoke thoses knocking or clicking noises on your Bmw Serie 1 F20. The main cause of these trouble generally comes from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible obstruction will inevitably result in a malfunction of the injector.

The side effects of injector noise on Bmw Serie 1 F20
Now that we have examined the several causes for injector noise on your Bmw Serie 1 F20, we will end by stating the possible 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 promptly become serious….
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 noticed by drivers is a significant 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 promptly harm your cylinders or pistons and your engine may tighten.
Here are three little suggestions to limit the risks associated 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>
