It is never pleasurable to experience an injector noise on your Bmw Serie 1 F21. It is a noise that comes up continually, usually when you accelerate or your engine is idling. However, this symptom may be relating to multiple types of trouble with your automobile injectors. It may not be anything major, but when a frequent noise appears, you have to be sure. Most importantly since fixing your Bmw Serie 1 F21’s injectors can be costly. That’s why our team decided to prepare this article content in order to help you see more clearly, learn about the different conceivable failures and distinguish your problem. To do this, we will first look at the normal functioning and usefulness of the injectors in your Bmw Serie 1 F21, then at the conceivable causes from which an injector noise may come.
Purposes of the injectors
Injectors are a very important component of the operation of your engine. 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 possibility, 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 accumulated from the various sensors equipping the automobile (engine temperature, acceleration level, engine speed, etc.). Their purpose 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 causes of a clicking or knocking noise caused by the injectors of your Bmw Serie 1 F21
Finding out injector noises on your Bmw Serie 1 F21 may come from different sources, we will now center on the potential causes of these. In most cases, the usual noise of a faulty injector is of the snap type. Here are the several sources of these noises and the solutions to be adopted to prevent them. If you experience another clicking noise but it is not from your injectors, we encourage you to read this article content about clicking noise on Bmw Serie 1 F21 to locate the reason.
The causes for injector clicking or knocking noise Bmw Serie 1 F21
A clicking or knocking noise from your injectors can be explained for different causes. Indeed, the injectors of your Bmw Serie 1 F21 have three main tasks, to control the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to ease its combustion. Then, its objective is to deal with the air/fuel dosage and at last the homogeneity of the mixture, always with the target of improving combustion. If one of these three tasks is modified, 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 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 Bmw Serie 1 F21. The main reason of these situations in most cases originates 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. If after checking, this noise originates from another part of the engine of your Bmw Serie 1 F21, check this article content for more infos.
The repercussions of injector noise on Bmw Serie 1 F21
Now that we have analyzed the diverse causes for injector noise on your Bmw Serie 1 F21, we will end by stating the possible effects of malfunctioning one or more of your injectors. Whether only one is blocked, or broken, or your entire fuel rail is involved, you cannot escape these repercussions which can promptly become critical….
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 regular repercussions noticed by drivers is a significant loss of power. Indeed, 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 affect your cylinders or pistons and your engine may tighten.
Here are three little recommendations to limit the risks linked 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>
