It is rarely ever pleasant to listen an injector noise on your Nissan Rogue. It is a noise that appears continually, usually when you accelerate or your engine is idling. However, this sign may be connected to different kind of concerns with your vehicle injectors. It may not be anything major, but when a repeated noise shows up, you have to be sure. Especially since replacing your Nissan Rogue’s injectors can be costly. That’s why our team decided to create this article in order to help you see more clearly, learn about the different conceivable failures and identify your problem. To do this, we will first look at the normal functioning and usefulness of the injectors in your Nissan Rogue, then at the conceivable triggers from which an injector noise may come.
Benefits of the injectors
Injectors are a very vital part of the operation of your engine. They were brought in to the modern cars 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 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 collected 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 triggers of a clicking or knocking noise caused by the injectors of your Nissan Rogue
Listening injector noises on your Nissan Rogue may come from different locations, we will now concentrate on the potential triggers of these. In general, the common noise of a faulty injector is of the snap type. Here are the several origins of these noises and the solutions to be put into practice to stop them. If you listen another clicking noise but it is not from your injectors, we encourage you to go through this article about clicking noise on Nissan Rogue to locate the trigger.
The causes for injector clicking or knocking noise Nissan Rogue
A clicking or knocking noise from your injectors can be justified by different causes. Indeed, the injectors of your Nissan Rogue have three main tasks, 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 finally the homogeneity of the mixture, always with the goal of improving combustion. If one of these three functions is modified, the main functionality of the injectors will be disturbed 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 trigger thoses knocking or clicking noises on your Nissan Rogue. The main trigger of these situations commonly originates from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible obstruction will inevitably produce a malfunction of the injector. If after checking, this noise originates from another part of the engine of your Nissan Rogue, read this article for more infos.
The effects of injector noise on Nissan Rogue
Now that we have examined the diverse reasons for injector noise on your Nissan Rogue, we will end by stating the possible end result of malfunctioning one or more of your injectors. Whether only one is obstructed, 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 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 basic effects experienced 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 degrading one of your pistons or your engine. Poor combustion will almost instantly affect your cylinders or pistons and your engine may tighten.
Here are three little suggestions 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>
