It is hardly ever pleasant to listen an injector noise on your Nissan Micra 4. It is a noise that happens repeatedly, usually when you accelerate or your engine is idling. However, this indicator may be related to multiple kind of problems with your car injectors. It may not be anything serious, but when a frequent noise arises, you have to be sure. Most importantly since repairing your Nissan Micra 4’s injectors can be costly. That’s why our team decided to create this article content in order to help you see more clearly, learn about the different plausible failures and identify your issue. To do this, we will first look at the normal functioning and usefulness of the injectors in your Nissan Micra 4, then at the plausible triggers from which an injector noise may come.
Functions of the injectors
Injectors are a very vital part of the operation of your engine motor. They were released to the modern automobiles about 20 years ago. Before their arrival, 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 possibility, 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 accumulated from the various sensors equipping the car (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 get the best possible combustion in the cylinders.
The different causes of a clicking or knocking noise based on the injectors of your Nissan Micra 4
Finding out injector noises on your Nissan Micra 4 may result from different sources, we will now focus on the potential causes of these. In most cases, the usual noise of a faulty injector is of the snap type. Here are the several sources of these noises and the solutions to be adopted to get rid of them. If you listen another clicking noise but it is not from your injectors, we suggest you to examine this article content about clicking noise on Nissan Micra 4 to locate the cause.
The causes for injector clicking or knocking noise Nissan Micra 4
A clicking or knocking noise from your injectors can be justified by different causes. In fact, the injectors of your Nissan Micra 4 have three main tasks, to control the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to ease its combustion. Then, its goal is to deal with the air/fuel dosage and at last the homogeneity of the mixture, always with the objective of improving combustion. If one of these three features 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 induce thoses knocking or clicking noises on your Nissan Micra 4. The main cause of these problems generally comes from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible obstruction will inevitably cause a malfunction of the injector.

The effects of injector noise on Nissan Micra 4
Now that we have examined the several causes for injector noise on your Nissan Micra 4, 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 effects which can promptly become considerable….
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 common consequences experienced 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 inevitably have a loss of power
Finally, you risk degrading one of your pistons or your engine. Poor combustion will promptly damage your cylinders or pistons and your engine may tighten.
Here are three little tips 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>
