It is never pleasant to perceive an injector noise on your Nissan NV. It is a noise that appears continually, usually when you accelerate or your engine is idling. However, this indicator may be linked to several sort of problems with your car injectors. It may not be anything serious, but when a repeated noise shows up, you have to be sure. Especially since fixing your Nissan NV’s injectors can be expensive. That’s why our team chose to produce this content page in order to help you see more clearly, learn about the different possible failures and identify your issue. To do this, we will first look at the normal running and usefulness of the injectors in your Nissan NV, then at the possible reasons from which an injector noise may come.injector-noise-nissan-nv

Functions of the injectors

Injectors are a very useful part of the operation of your engine motor. They were released to the modern vehicles 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 collected from the various sensors equipping the car (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 causes of a clicking or knocking noise based on the injectors of your Nissan NV

Experiencing injector noises on your Nissan NV may come from different locations, we will now focus 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 applied to eliminate them. If you perceive another clicking noise but it is not from your injectors, we encourage you to go through this content page about clicking noise on Nissan NV to find the cause.

The causes for injector clicking or knocking noise Nissan NV

A clicking or knocking noise from your injectors can be explained for different causes. Indeed, the injectors of your Nissan NV 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 task is to manage 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 disrupted 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 NV. The main cause of these situations generally comes 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.

The consequences of injector noise on Nissan NV

Now that we have examined the diverse reasons for injector noise on your Nissan NV, we will end by stating the possible effects 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 promptly 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 repercussions noticed by drivers is a serious loss of power. Indeed, if your engine is running on 3 out of 4 cylinders for example, you will surely have a loss of power
Finally, you risk deteriorating one of your pistons or your engine. Poor combustion will promptly affect your cylinders or pistons and your engine may tighten.
Here are three little suggestions to limit the risks associated 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 changing your diesel fuel filter regularly>
