It is never relaxing to acknowledge an injector noise on your Nissan Frontier. It is a noise that happens repeatedly, usually when you accelerate or your engine is idling. However, this warning sign may be relating to multiple types of complications with your car injectors. It may not be anything severe, but when a persistent noise appears, you have to be sure. Especially since repairing your Nissan Frontier’s injectors can be expensive. That’s why our team chose to create this article content in order to support you see more clearly, learn about the different plausible failures and identify your issue. To do this, we will first look at the normal functioning and usefulness of the injectors in your Nissan Frontier, then at the plausible triggers from which an injector noise may come.injector-noise-nissan-frontier

Benefits of the injectors

Injectors are a very useful part of the operation of your engine unit. They were launched 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 received from the various sensors equipping the car (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 reasons of a clicking or knocking noise coming from the injectors of your Nissan Frontier

Discovering injector noises on your Nissan Frontier may come from different locations, we will now focus on the potential causes of these. In most cases, the common noise of a faulty injector is of the snap type. Here are the several sources of these noises and the solutions to be adopted to eliminate them. If you acknowledge another clicking noise but it is not from your injectors, we suggest you to go through this article content about clicking noise on Nissan Frontier to discover the cause.

The explanations for injector clicking or knocking noise Nissan Frontier

A clicking or knocking noise from your injectors can be justified by different explanations. Indeed, the injectors of your Nissan Frontier 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 mission is to deal with the air/fuel dosage and at last the homogeneity of the mixture, always with the objective of improving combustion. If one of these three attributes is altered, 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 due to bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will induce thoses knocking or clicking noises on your Nissan Frontier. The main cause of these situations usually comes from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible obstruction will inevitably cause a malfunction of the injector.

The effects of injector noise on Nissan Frontier

Now that we have reviewed the diverse causes for injector noise on your Nissan Frontier, we will end by stating the possible consequences 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 effects which can promptly become critical….
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 known repercussions 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 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 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>
