It is hardly ever pleasant to listen to an injector noise on your Mini Cooper. It is a noise that appears repeatedly, usually when you accelerate or your engine is idling. However, this indication may be related to multiple kind of concerns with your automobile injectors. It may not be anything major, but when a recurrent noise shows up, you have to be sure. Specifically since fixing your Mini Cooper’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 plausible failures and establish your problem. To do this, we will first look at the normal function and usefulness of the injectors in your Mini Cooper, then at the plausible triggers from which an injector noise may come.
Benefits of the injectors
Injectors are a very important part of the operation of your engine. They were brought in to the modern cars 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 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 obtained 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 coming from the injectors of your Mini Cooper
Listening injector noises on your Mini Cooper may come from different locations, we will now center on the potential triggers of these. In general, the regular noise of a faulty injector is of the snap type. Here are the different origins of these noises and the solutions to be implemented to prevent them. If you listen to another clicking noise but it is not from your injectors, we encourage you to examine this content about clicking noise on Mini Cooper to find the cause.
The explanations for injector clicking or knocking noise Mini Cooper
A clicking or knocking noise from your injectors can be explained for different explanations. In fact, the injectors of your Mini Cooper have three main tasks, to control the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to ease its combustion. Then, its goal is to control the air/fuel dosage and at last the homogeneity of the mixture, always with the objective of improving combustion. If one of these three characteristics is modified, the main functionality of the injectors will be disrupted and this will lead to poor combustion. This bad combustion will be a violent explosion in the cylinders because of bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will provoke thoses knocking or clicking noises on your Mini Cooper. The main cause of these problems generally comes from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible obstruction will inevitably end up in a malfunction of the injector. If after checking, this noise comes from another element of the engine of your Mini Cooper, read this content for more infos.
The end result of injector noise on Mini Cooper
Now that we have analyzed the diverse reasons for injector noise on your Mini Cooper, we will end by stating the possible side 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 side effects which can quickly 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 common effects noticed by drivers is a noticeable loss of power. In fact, 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 quickly affect your cylinders or pistons and your engine may tighten.
Here are three little suggestions 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 changing your diesel fuel filter regularly>
