It is never pleasurable to acknowledge an injector noise on your Bmw Serie 1 E82. It is a noise that arises frequently, usually when you accelerate or your engine is idling. However, this sign may be connected to different kind of concerns with your automobile injectors. It may not be anything serious, but when a repeated noise happens, you have to be sure. Specifically since fixing your Bmw Serie 1 E82’s injectors can be expensive. That’s why our team decided to produce this content in order to support you see more clearly, learn about the different possible failures and establish your issue. To do this, we will first look at the normal functioning and usefulness of the injectors in your Bmw Serie 1 E82, then at the possible causes from which an injector noise may come.
Benefits of the injectors
Injectors are a very vital element of the operation of your engine. They were released to the modern cars 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 collected from the various sensors equipping the automobile (engine temperature, acceleration level, engine speed, etc.). Their aim 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 origins of a clicking or knocking noise caused by the injectors of your Bmw Serie 1 E82
Discovering injector noises on your Bmw Serie 1 E82 may result from different sources, we will now focus on the potential causes of these. In most cases, the typical 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 prevent them. If you acknowledge another clicking noise but it is not from your injectors, we advise you to go through this content about clicking noise on Bmw Serie 1 E82 to find the cause.
The reasons for injector clicking or knocking noise Bmw Serie 1 E82
A clicking or knocking noise from your injectors can be justified by different reasons. Indeed, the injectors of your Bmw Serie 1 E82 have three main missions, to control the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to facilitate its combustion. Then, its mission is to control the air/fuel dosage and at last the homogeneity of the mixture, always with the target of improving combustion. If one of these three characteristics is altered, 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 Serie 1 E82. The main cause of these situations in most cases originates from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible obstruction will inevitably end in a malfunction of the injector. If after verifying, this noise originates from another part of the engine of your Bmw Serie 1 E82, read this content for more informations.
The end result of injector noise on Bmw Serie 1 E82
Now that we have examined the several causes for injector noise on your Bmw Serie 1 E82, we will end by stating the possible effects of malfunctioning one or more of your injectors. Whether only one is obstructed, or damaged, or your entire fuel rail is involved, you cannot escape these effects which can promptly become severe….
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 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 obviously 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 swapping your diesel fuel filter regularly>
