It is hardly ever enjoyable to acknowledge an injector noise on your Nissan Versa. It is a noise that comes up continually, usually when you accelerate or your engine is idling. However, this sign may be relating to several types of problems with your car injectors. It may not be anything severe, but when a repeated noise shows up, you have to be sure. Specifically since replacing your Nissan Versa’s injectors can be costly. That’s why our team decided to write this article in order to help you see more clearly, learn about the different conceivable failures and establish your trouble. To do this, we will first look at the normal functioning and usefulness of the injectors in your Nissan Versa, then at the conceivable triggers from which an injector noise may come.injector-noise-nissan-versa

Functions of the injectors

Injectors are a very significant element of the operation of your engine unit. They were introduced to the modern cars 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 possibility, 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 compiled from the various sensors equipping the car (engine temperature, acceleration level, engine speed, etc.). Their objective 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 Versa

Hearing injector noises on your Nissan Versa may originate from different locations, we will now look into the potential triggers of these. Generally, the typical noise of a faulty injector is of the snap type. Here are the several sources of these noises and the solutions to be put into practice to stop them. If you acknowledge another clicking noise but it is not from your injectors, we advise you to go through this article about clicking noise on Nissan Versa to find the reason.

The explanations for injector clicking or knocking noise Nissan Versa

A clicking or knocking noise from your injectors can be explained for different explanations. In fact, the injectors of your Nissan Versa have three main tasks, to control the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to facilitate its combustion. Then, its mission is to control the air/fuel dosage and at last the homogeneity of the mixture, always with the target of improving combustion. If one of these three features is modified, the main purpose of the injectors will be disturbed 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 Versa. The main reason of these trouble 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 end up in a malfunction of the injector.

The consequences of injector noise on Nissan Versa

Now that we have analyzed the diverse reasons for injector noise on your Nissan Versa, we will end by stating the possible side 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 fairly quickly become critical….
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 known consequences noticed by drivers is a severe loss of power. In fact, if your engine is running on 3 out of 4 cylinders for example, you will surely have a loss of power
Finally, you risk degrading one of your pistons or your engine. Poor combustion will fairly quickly affect your cylinders or pistons and your engine may tighten.
Here are three little tips to limit the risks relating 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 changing your diesel fuel filter regularly>
