It is never enjoyable to listen to an injector noise on your Nissan Note. It is a noise that appears continually, usually when you accelerate or your engine is idling. However, this warning sign may be linked to multiple kind of complications with your vehicle injectors. It may not be anything serious, but when a persistent noise arises, you have to be sure. Especially since replacing your Nissan Note’s injectors can be expensive. That’s why our team decided to write this content in order to support you see more clearly, learn about the different possible failures and distinguish your trouble. To do this, we will first look at the normal running and usefulness of the injectors in your Nissan Note, then at the possible reasons from which an injector noise may come.
Attributes of the injectors
Injectors are a very important component of the operation of your engine unit. They were brought in 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 opportunity, 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 compiled from the various sensors equipping the vehicle (engine temperature, acceleration level, engine speed, etc.). Their goal 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 origins of a clicking or knocking noise caused by the injectors of your Nissan Note
Discovering injector noises on your Nissan Note may come from different origins, we will now concentrate on the potential triggers of these. Generally, 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 used to get rid of them. If you listen to another clicking noise but it is not from your injectors, we recommend you to read this content about clicking noise on Nissan Note to discover the reason.
The causes for injector clicking or knocking noise Nissan Note
A clicking or knocking noise from your injectors can be justified by different causes. Indeed, the injectors of your Nissan Note have three main missions, to control the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to facilitate 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 features is altered, 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 as a consequence of bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will trigger thoses knocking or clicking noises on your Nissan Note. The main reason of these problems in most cases originates from a particle that gets into the injectors. The accuracy 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 component of the engine of your Nissan Note, check this content for more informations.
The end result of injector noise on Nissan Note
Now that we have examined the several reasons for injector noise on your Nissan Note, we will end by stating the possible effects of malfunctioning one or more of your injectors. Whether only one is blocked, or damaged, or your entire fuel rail is involved, you cannot escape these repercussions which can promptly become major….
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 basic repercussions experienced by drivers is a distinctive loss of power. Indeed, if your engine is running on 3 out of 4 cylinders for example, you will inevitably have a loss of power
Finally, you risk deteriorating one of your pistons or your engine. Poor combustion will promptly harm 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 swapping your diesel fuel filter regularly>
