It is rarely ever enjoyable to acknowledge an injector noise on your Bmw Serie 1. It is a noise that comes up frequently, usually when you accelerate or your engine is idling. However, this indication may be linked to multiple sort of trouble with your automobile injectors. It may not be anything serious, but when a continuing noise comes out, you have to be sure. Especially since fixing your Bmw Serie 1’s injectors can be costly. That’s why our team chose to compose this content in order to help you see more clearly, learn about the different possible failures and establish your trouble. To do this, we will first look at the normal function and usefulness of the injectors in your Bmw Serie 1, then at the possible reasons from which an injector noise may come.
Attributes of the injectors
Injectors are a very useful component of the operation of your engine motor. They were brought in to the modern automobiles 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 ability, 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 triggers of a clicking or knocking noise based on the injectors of your Bmw Serie 1
Discovering injector noises on your Bmw Serie 1 may result from different locations, we will now look into the potential triggers of these. In general, the regular noise of a faulty injector is of the snap type. Here are the several origins of these noises and the solutions to be applied to prevent them. If you acknowledge another clicking noise but it is not from your injectors, we encourage you to examine this content about clicking noise on Bmw Serie 1 to find the trigger.
The reasons for injector clicking or knocking noise Bmw Serie 1
A clicking or knocking noise from your injectors can be explained for different reasons. Indeed, the injectors of your Bmw Serie 1 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 task is to manage the air/fuel dosage and at last the homogeneity of the mixture, always with the aim of improving combustion. If one of these three features is modified, the main role 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 induce thoses knocking or clicking noises on your Bmw Serie 1. The main trigger of these problems usually comes from a particle that gets into the injectors. The accuracy 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 part of the engine of your Bmw Serie 1, have a look at this content for more infos.
The effects of injector noise on Bmw Serie 1
Now that we have reviewed the different reasons for injector noise on your Bmw Serie 1, we will end by stating the possible end result 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 repercussions which can almost instantly 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 known effects experienced by drivers is a severe loss of power. Indeed, if your engine is running on 3 out of 4 cylinders for example, you will inevitably have a loss of power
Finally, you risk deteriorating one of your pistons or your engine. Poor combustion will almost instantly damage your cylinders or pistons and your engine may tighten.
Here are three little recommendations 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>
