It is rarely ever pleasurable to experience an injector noise on your Nissan Cube. It is a noise that arises regularly, usually when you accelerate or your engine is idling. However, this symptom may be linked to several types of trouble with your vehicle injectors. It may not be anything severe, but when a frequent noise appears, you have to be sure. Especially since replacing your Nissan Cube’s injectors can be expensive. That’s why our team decided to create this content page in order to help you see more clearly, learn about the different plausible failures and distinguish your issue. To do this, we will first look at the normal running and usefulness of the injectors in your Nissan Cube, then at the plausible reasons from which an injector noise may come.
Attributes of the injectors
Injectors are a very useful part of the operation of your engine motor. They were launched to the modern vehicles 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 opportunity, 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 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 obtain the best possible combustion in the cylinders.
The different reasons of a clicking or knocking noise caused by the injectors of your Nissan Cube
Finding out injector noises on your Nissan Cube may originate from different sources, we will now focus on the potential causes 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 used to get rid of them. If you experience another clicking noise but it is not from your injectors, we suggest you to read this content page about clicking noise on Nissan Cube to discover the trigger.
The causes for injector clicking or knocking noise Nissan Cube
A clicking or knocking noise from your injectors can be explained for different causes. Indeed, the injectors of your Nissan Cube 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 manage 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 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 provoke thoses knocking or clicking noises on your Nissan Cube. The main trigger of these concerns generally originates from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible blockage will inevitably lead to a malfunction of the injector. If after verifying, this noise originates from another part of the engine of your Nissan Cube, check this content page for more infos.
The end result of injector noise on Nissan Cube
Now that we have examined the several causes for injector noise on your Nissan Cube, we will end by stating the possible consequences 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 consequences which can almost instantly 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 basic repercussions felt by drivers is a noticeable loss of power. Indeed, 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 harm your cylinders or pistons and your engine may tighten.
Here are three little recommendations 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 swapping your diesel fuel filter regularly>
