It is never pleasant to hear an injector noise on your Infiniti Q60. It is a noise that appears continually, usually when you accelerate or your engine is idling. However, this warning sign may be connected to several kind of concerns with your automobile injectors. It may not be anything serious, but when a persistent noise comes out, you have to be sure. Specifically since repairing your Infiniti Q60’s injectors can be expensive. That’s why our team decided to create this content page in order to help you see more clearly, learn about the different conceivable failures and identify your issue. To do this, we will first look at the normal running and usefulness of the injectors in your Infiniti Q60, then at the conceivable causes from which an injector noise may come.injector-noise-infiniti-q60

Purposes of the injectors

Injectors are a very fundamental element of the operation of your engine. They were introduced to the modern automobiles about 20 years ago. Before their introduction, more conventional carburettor-type intake systems were employed, 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 accumulated from the various sensors equipping the automobile (engine temperature, acceleration level, engine speed, etc.). Their aim 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 coming from the injectors of your Infiniti Q60

Hearing injector noises on your Infiniti Q60 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 different origins of these noises and the solutions to be implemented to get rid of them. If you hear another clicking noise but it is not from your injectors, we recommend you to read this content page about clicking noise on Infiniti Q60 to find the trigger.

The reasons for injector clicking or knocking noise Infiniti Q60

A clicking or knocking noise from your injectors can be explained for different reasons. Indeed, the injectors of your Infiniti Q60 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 task is to manage the air/fuel dosage and finally the homogeneity of the mixture, always with the goal of improving combustion. If one of these three tasks 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 Infiniti Q60. The main trigger of these trouble 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 end in a malfunction of the injector.

The consequences of injector noise on Infiniti Q60

Now that we have examined the different causes for injector noise on your Infiniti Q60, we will end by stating the possible end result 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 almost instantly become severe….
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 repercussions felt by drivers is a severe loss of power. Indeed, if your engine is running on 3 out of 4 cylinders for example, you will undoubtedly have a loss of power
Finally, you risk degrading one of your pistons or your engine. Poor combustion will almost instantly harm your cylinders or pistons and your engine may tighten.
Here are three little tips to limit the risks connected 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 swapping your diesel fuel filter regularly>
