It is hardly ever enjoyable to listen to an injector noise on your BMW X1. It is a noise that arises frequently, usually when you accelerate or your engine is idling. However, this symptom may be related to different types of trouble 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 X1’s injectors can be expensive. That’s why our team decided to create this content in order to support you see more clearly, learn about the different plausible failures and establish your issue. To do this, we will first look at the normal functioning and usefulness of the injectors in your BMW X1, then at the plausible reasons from which an injector noise may come.
Purposes of the injectors
Injectors are a very important element of the operation of your engine. They were introduced to the modern vehicles 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 precisely (quantity of fuel injected, air/fuel mixture) via the analysis of the data compiled 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 triggers of a clicking or knocking noise based on the injectors of your BMW X1
Finding out injector noises on your BMW X1 may originate from different origins, we will now focus on the potential triggers of these. In most cases, the common noise of a faulty injector is of the snap type. Here are the different sources of these noises and the solutions to be used to prevent them. If you listen to another clicking noise but it is not from your injectors, we recommend you to go through this content about clicking noise on BMW X1 to find the trigger.
The reasons for injector clicking or knocking noise BMW X1
A clicking or knocking noise from your injectors can be justified by different reasons. Indeed, the injectors of your BMW X1 have three main tasks, to manage the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to facilitate its combustion. Then, its goal is to control the air/fuel dosage and finally the homogeneity of the mixture, always with the target of improving combustion. If one of these three features 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 induce thoses knocking or clicking noises on your BMW X1. The main trigger of these trouble 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 lead to a malfunction of the injector. If after checking, this noise comes from another element of the engine of your BMW X1, have a look at this content for more informations.
The side effects of injector noise on BMW X1
Now that we have examined the diverse reasons for injector noise on your BMW X1, we will end by stating the possible consequences 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 side effects which can fairly quickly become serious….
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 common repercussions felt by drivers is a noticeable 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 fairly quickly damage your cylinders or pistons and your engine may tighten.
Here are three little recommendations 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 swapping your diesel fuel filter regularly>
