It is never pleasurable to hear an injector noise on your Nissan Armada. It is a noise that happens frequently, usually when you accelerate or your engine is idling. However, this indicator may be related to multiple kind of trouble with your vehicle injectors. It may not be anything severe, but when a continuing noise comes out, you have to be sure. Especially since fixing your Nissan Armada’s injectors can be expensive. That’s why our team chose to prepare this article content in order to help you see more clearly, learn about the different possible failures and determine your issue. To do this, we will first look at the normal functioning and usefulness of the injectors in your Nissan Armada, then at the possible reasons from which an injector noise may come.
Benefits of the injectors
Injectors are a very vital part of the operation of your engine unit. They were released to the modern cars 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 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 collected from the various sensors equipping the vehicle (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 based on the injectors of your Nissan Armada
Finding out injector noises on your Nissan Armada may come from different origins, we will now focus on the potential triggers of these. Generally, the common noise of a faulty injector is of the snap type. Here are the different sources of these noises and the solutions to be used to stop them. If you hear another clicking noise but it is not from your injectors, we advise you to examine this article content about clicking noise on Nissan Armada to discover the reason.
The explanations for injector clicking or knocking noise Nissan Armada
A clicking or knocking noise from your injectors can be explained for different explanations. In fact, the injectors of your Nissan Armada have three main missions, to manage the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to ease its combustion. Then, its goal is to control the air/fuel dosage and finally the homogeneity of the mixture, always with the objective of improving combustion. If one of these three functions 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 Armada. The main reason of these problems commonly comes 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 checking, this noise comes from another part of the engine of your Nissan Armada, have a look at this article content for more infos.
The side effects of injector noise on Nissan Armada
Now that we have analyzed the several causes for injector noise on your Nissan Armada, 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 side effects 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 common repercussions felt by drivers is a serious loss of power. In fact, 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 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>
