It is rarely ever pleasant to perceive an injector noise on your BMW X4. It is a noise that happens continually, usually when you accelerate or your engine is idling. However, this indication may be related to multiple sort of complications with your automobile injectors. It may not be anything major, but when a continuing noise comes out, you have to be sure. Most importantly since fixing your BMW X4’s injectors can be costly. That’s why our team decided to create this content page in order to support 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 X4, then at the possible reasons from which an injector noise may come.
Benefits of the injectors
Injectors are a very vital part of the operation of your engine. They were brought in to the modern automobiles about 20 years ago. Before their introduction, 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 collected 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 reasons of a clicking or knocking noise based on the injectors of your BMW X4
Hearing injector noises on your BMW X4 may result from different sources, we will now center on the potential triggers of these. Generally, the usual noise of a faulty injector is of the snap type. Here are the different sources of these noises and the solutions to be applied to stop them. If you perceive another clicking noise but it is not from your injectors, we recommend you to read this content page about clicking noise on BMW X4 to locate the reason.
The causes for injector clicking or knocking noise BMW X4
A clicking or knocking noise from your injectors can be explained for different causes. Indeed, the injectors of your BMW X4 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 task is to deal with the air/fuel dosage and at last the homogeneity of the mixture, always with the goal of improving combustion. If one of these three attributes 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 due to bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will provoke thoses knocking or clicking noises on your BMW X4. The main reason of these concerns in most cases comes from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible blockage will inevitably end in a malfunction of the injector. If after verifying, this noise comes from another component of the engine of your BMW X4, have a look at this content page for more infos.
The side effects of injector noise on BMW X4
Now that we have analyzed the different reasons for injector noise on your BMW X4, we will end by stating the possible end result 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 effects which can quickly become critical….
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 repercussions noticed by drivers is a serious loss of power. Indeed, if your engine is running on 3 out of 4 cylinders for example, you will surely have a loss of power
Finally, you risk deteriorating one of your pistons or your engine. Poor combustion will quickly harm your cylinders or pistons and your engine may tighten.
Here are three little suggestions 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 changing your diesel fuel filter regularly>
