It is rarely ever pleasurable to perceive an injector noise on your Nissan Micra 5. It is a noise that appears frequently, usually when you accelerate or your engine is idling. However, this sign may be relating to different sort of trouble with your automobile injectors. It may not be anything severe, but when a frequent noise shows up, you have to be sure. Especially since repairing your Nissan Micra 5’s injectors can be costly. That’s why our team chose to compose this content page in order to help you see more clearly, learn about the different conceivable failures and establish your problem. To do this, we will first look at the normal functioning and usefulness of the injectors in your Nissan Micra 5, then at the conceivable triggers from which an injector noise may come.
Benefits of the injectors
Injectors are a very fundamental part of the operation of your engine motor. They were brought in to the modern automobiles about 20 years ago. Before their arrival, 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 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 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 reasons of a clicking or knocking noise coming from the injectors of your Nissan Micra 5
Hearing injector noises on your Nissan Micra 5 may result from different origins, we will now focus on the potential causes of these. Generally, the usual noise of a faulty injector is of the snap type. Here are the different sources of these noises and the solutions to be adopted to stop them. If you perceive another clicking noise but it is not from your injectors, we recommend you to examine this content page about clicking noise on Nissan Micra 5 to find the reason.
The causes for injector clicking or knocking noise Nissan Micra 5
A clicking or knocking noise from your injectors can be explained for different causes. Indeed, the injectors of your Nissan Micra 5 have three main missions, to manage the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to facilitate its combustion. Then, its goal is to deal with the air/fuel dosage and at last the homogeneity of the mixture, always with the target of improving combustion. If one of these three attributes 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 provoke thoses knocking or clicking noises on your Nissan Micra 5. The main reason of these concerns 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 result in a malfunction of the injector. If after verifying, this noise originates from another component of the engine of your Nissan Micra 5, browse this content page for more infos.
The end result of injector noise on Nissan Micra 5
Now that we have analyzed the several reasons for injector noise on your Nissan Micra 5, we will end by stating the possible side effects of malfunctioning one or more of your injectors. Whether only one is blocked, or broken, or your entire fuel rail is involved, you cannot escape these consequences which can fairly quickly become severe….
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 distinctive 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 deteriorating one of your pistons or your engine. Poor combustion will fairly quickly 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 swapping your diesel fuel filter regularly>
