It is hardly ever pleasant to hear an injector noise on your Mini Countryman 2. It is a noise that happens frequently, usually when you accelerate or your engine is idling. However, this indicator may be linked to different kind of concerns with your vehicle injectors. It may not be anything serious, but when a continuing noise arises, you have to be sure. Specifically since repairing your Mini Countryman 2’s injectors can be costly. That’s why our team chose to create this content page in order to support you see more clearly, learn about the different conceivable failures and determine your issue. To do this, we will first look at the normal function and usefulness of the injectors in your Mini Countryman 2, then at the conceivable reasons from which an injector noise may come.
Functions of the injectors
Injectors are a very significant element of the operation of your engine unit. They were launched to the modern vehicles about 20 years ago. Before their appearance, 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 possibility, 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 vehicle (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 get the best possible combustion in the cylinders.
The different causes of a clicking or knocking noise based on the injectors of your Mini Countryman 2
Hearing injector noises on your Mini Countryman 2 may result from different sources, we will now concentrate on the potential causes of these. Generally, the typical noise of a faulty injector is of the snap type. Here are the different origins of these noises and the solutions to be put into practice to stop them. If you hear another clicking noise but it is not from your injectors, we advise you to examine this content page about clicking noise on Mini Countryman 2 to locate the reason.
The explanations for injector clicking or knocking noise Mini Countryman 2
A clicking or knocking noise from your injectors can be explained for different explanations. In fact, the injectors of your Mini Countryman 2 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 objective is to manage the air/fuel dosage and finally the homogeneity of the mixture, always with the target of improving combustion. If one of these three attributes 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 because of bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will induce thoses knocking or clicking noises on your Mini Countryman 2. The main reason of these concerns in most cases originates 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 originates from another element of the engine of your Mini Countryman 2, read this content page for more infos.
The end result of injector noise on Mini Countryman 2
Now that we have reviewed the diverse causes for injector noise on your Mini Countryman 2, 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 side effects which can almost instantly 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 consequences felt by drivers is a significant 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 almost instantly 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>
