It is hardly ever enjoyable to acknowledge an injector noise on your Infiniti G. It is a noise that arises continually, usually when you accelerate or your engine is idling. However, this symptom may be linked to several sort of concerns with your vehicle injectors. It may not be anything severe, but when a recurrent noise happens, you have to be sure. Especially since fixing your Infiniti G’s injectors can be expensive. That’s why our team chose to compose this article content in order to help you see more clearly, learn about the different plausible failures and identify your trouble. To do this, we will first look at the normal running and usefulness of the injectors in your Infiniti G, then at the plausible causes from which an injector noise may come.injector-noise-infiniti-g

Benefits of the injectors

Injectors are a very important element of the operation of your engine. They were released to the modern vehicles about 20 years ago. Before their appearance, 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 vehicle (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 obtain the best possible combustion in the cylinders.

The different causes of a clicking or knocking noise based on the injectors of your Infiniti G

Hearing injector noises on your Infiniti G may result from different locations, we will now concentrate on the potential causes of these. In general, the typical noise of a faulty injector is of the snap type. Here are the several origins of these noises and the solutions to be applied to prevent them. If you acknowledge another clicking noise but it is not from your injectors, we recommend you to browse this article content about clicking noise on Infiniti G to discover the trigger.

The causes for injector clicking or knocking noise Infiniti G

A clicking or knocking noise from your injectors can be justified by different causes. In fact, the injectors of your Infiniti G 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 objective is to control the air/fuel dosage and finally the homogeneity of the mixture, always with the target of improving combustion. If one of these three features is altered, 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 as a consequence of bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will trigger thoses knocking or clicking noises on your Infiniti G. The main trigger of these concerns generally comes 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 verifying, this noise comes from another component of the engine of your Infiniti G, read this article content for more informations.

The repercussions of injector noise on Infiniti G

Now that we have examined the diverse reasons for injector noise on your Infiniti G, we will end by stating the possible effects of malfunctioning one or more of your injectors. Whether only one is blocked, or broken, or your entire fuel rail is involved, you cannot escape these effects which can fairly quickly 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 regular consequences noticed by drivers is a noticeable loss of power. In fact, if your engine is running on 3 out of 4 cylinders for example, you will obviously have a loss of power
Finally, you risk deteriorating one of your pistons or your engine. Poor combustion will fairly quickly harm your cylinders or pistons and your engine may tighten.
Here are three little tips 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 changing your diesel fuel filter regularly>
