It is never enjoyable to hear an injector noise on your Bmw Serie 4 F32. It is a noise that arises continually, usually when you accelerate or your engine is idling. However, this sign may be connected to different kind of complications with your automobile injectors. It may not be anything major, but when a continuing noise happens, you have to be sure. Especially since repairing your Bmw Serie 4 F32’s injectors can be expensive. That’s why our team chose to prepare this article in order to help you see more clearly, learn about the different possible failures and identify your trouble. To do this, we will first look at the normal function and usefulness of the injectors in your Bmw Serie 4 F32, then at the possible causes from which an injector noise may come.
Purposes of the injectors
Injectors are a very vital component of the operation of your engine motor. They were brought in to the modern automobiles about 20 years ago. Before their introduction, more conventional carburettor-type intake systems were employed, which handled the intake of air and fuel into the engine cylinders. With the injectors, manufacturers now have the ability, 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 received from the various sensors equipping the automobile (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 obtain the best possible combustion in the cylinders.
The different reasons of a clicking or knocking noise coming from the injectors of your Bmw Serie 4 F32
Listening injector noises on your Bmw Serie 4 F32 may come from different locations, we will now center 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 origins of these noises and the solutions to be applied to stop them. If you hear another clicking noise but it is not from your injectors, we suggest you to browse this article about clicking noise on Bmw Serie 4 F32 to find the reason.
The explanations for injector clicking or knocking noise Bmw Serie 4 F32
A clicking or knocking noise from your injectors can be explained for different explanations. Indeed, the injectors of your Bmw Serie 4 F32 have three main tasks, to manage the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to ease its combustion. Then, its task is to manage the air/fuel dosage and finally the homogeneity of the mixture, always with the goal of improving combustion. If one of these three tasks 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 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 4 F32. The main reason of these problems usually comes from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible obstruction will inevitably produce a malfunction of the injector. If after verifying, this noise comes from another element of the engine of your Bmw Serie 4 F32, browse this article for more informations.
The effects of injector noise on Bmw Serie 4 F32
Now that we have analyzed the several causes for injector noise on your Bmw Serie 4 F32, we will end by stating the possible effects of malfunctioning one or more of your injectors. Whether only one is clogged, or damaged, or your entire fuel rail is involved, you cannot escape these consequences which can fairly 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 basic consequences felt 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 deteriorating 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 changing your diesel fuel filter regularly>
