It is never relaxing to acknowledge an injector noise on your Volvo XC60. It is a noise that arises repeatedly, usually when you accelerate or your engine is idling. However, this warning sign may be connected to different types of trouble with your automobile injectors. It may not be anything major, but when a recurrent noise comes out, you have to be sure. Specifically since fixing your Volvo XC60’s injectors can be costly. That’s why our team chose to write this content page in order to support you see more clearly, learn about the different conceivable failures and distinguish your problem. To do this, we will first look at the normal functioning and usefulness of the injectors in your Volvo XC60, then at the conceivable reasons from which an injector noise may come.injector-noise-volvo-xc60

Benefits of the injectors

Injectors are a very useful part of the operation of your engine motor. 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 accurately (quantity of fuel injected, air/fuel mixture) via the analysis of the data obtained from the various sensors equipping the automobile (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 caused by the injectors of your Volvo XC60

Finding out injector noises on your Volvo XC60 may originate from different origins, we will now center on the potential triggers of these. In general, the typical noise of a faulty injector is of the snap type. Here are the different sources of these noises and the solutions to be implemented to eliminate them. If you acknowledge another clicking noise but it is not from your injectors, we recommend you to browse this content page about clicking noise on Volvo XC60 to locate the reason.

The explanations for injector clicking or knocking noise Volvo XC60

A clicking or knocking noise from your injectors can be justified by different explanations. Indeed, the injectors of your Volvo XC60 have three main tasks, to control the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to ease its combustion. Then, its mission is to manage the air/fuel dosage and finally the homogeneity of the mixture, always with the aim of improving combustion. If one of these three tasks is modified, the main role of the injectors will be disturbed 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 induce thoses knocking or clicking noises on your Volvo XC60. The main reason of these trouble generally originates from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible blockage will inevitably end up in a malfunction of the injector.

The repercussions of injector noise on Volvo XC60

Now that we have analyzed the several causes for injector noise on your Volvo XC60, we will end by stating the possible effects 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 effects which can quickly 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 known repercussions felt by drivers is a significant 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 deteriorating one of your pistons or your engine. Poor combustion will quickly affect your cylinders or pistons and your engine may tighten.
Here are three little tips to limit the risks associated 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>
