It is never enjoyable to listen to an injector noise on your Infiniti Q50. It is a noise that happens repeatedly, usually when you accelerate or your engine is idling. However, this sign may be linked to multiple sort of complications with your car injectors. It may not be anything severe, but when a persistent noise comes out, you have to be sure. Specifically since replacing your Infiniti Q50’s injectors can be costly. That’s why our team chose to produce this article in order to help you see more clearly, learn about the different conceivable failures and establish your problem. To do this, we will first look at the normal running and usefulness of the injectors in your Infiniti Q50, then at the conceivable triggers from which an injector noise may come.injector-noise-infiniti-q50

Benefits of the injectors

Injectors are a very useful element of the operation of your engine. They were released to the modern vehicles 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 opportunity, 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 accumulated 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 obtain the best possible combustion in the cylinders.

The different reasons of a clicking or knocking noise coming from the injectors of your Infiniti Q50

Experiencing injector noises on your Infiniti Q50 may come from different locations, we will now center on the potential causes 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 eliminate them. If you listen to another clicking noise but it is not from your injectors, we encourage you to read this article about clicking noise on Infiniti Q50 to discover the cause.

The reasons for injector clicking or knocking noise Infiniti Q50

A clicking or knocking noise from your injectors can be justified by different reasons. In fact, the injectors of your Infiniti Q50 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 objective is to manage the air/fuel dosage and finally the homogeneity of the mixture, always with the objective of improving combustion. If one of these three tasks is modified, the main functionality 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 Infiniti Q50. The main cause of these situations commonly comes from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible blockage will inevitably cause a malfunction of the injector. If after checking, this noise comes from another component of the engine of your Infiniti Q50, have a look at this article for more informations.

The effects of injector noise on Infiniti Q50

Now that we have reviewed the different causes for injector noise on your Infiniti Q50, we will end by stating the possible consequences of malfunctioning one or more of your injectors. Whether only one is obstructed, or damaged, or your entire fuel rail is involved, you cannot escape these side effects 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 effects noticed by drivers is a distinctive loss of power. In fact, if your engine is running on 3 out of 4 cylinders for example, you will inevitably have a loss of power
Finally, you risk degrading one of your pistons or your engine. Poor combustion will almost instantly damage 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 changing your diesel fuel filter regularly>
