It is rarely ever enjoyable to perceive an injector noise on your Volvo S60. It is a noise that appears continually, usually when you accelerate or your engine is idling. However, this warning sign may be linked to different types of trouble with your car injectors. It may not be anything serious, but when a continuing noise shows up, you have to be sure. Most importantly since replacing your Volvo S60’s injectors can be costly. That’s why our team chose to create this article content in order to help you see more clearly, learn about the different possible failures and identify your problem. To do this, we will first look at the normal function and usefulness of the injectors in your Volvo S60, then at the possible triggers from which an injector noise may come.injector-noise-volvo-s60

Functions of the injectors

Injectors are a very important element of the operation of your engine motor. They were launched to the modern cars about 20 years ago. Before their arrival, 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 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 goal 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 causes of a clicking or knocking noise caused by the injectors of your Volvo S60

Discovering injector noises on your Volvo S60 may result 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 several sources of these noises and the solutions to be put into practice to prevent them. If you perceive another clicking noise but it is not from your injectors, we encourage you to go through this article content about clicking noise on Volvo S60 to find the trigger.

The explanations for injector clicking or knocking noise Volvo S60

A clicking or knocking noise from your injectors can be justified by different explanations. In fact, the injectors of your Volvo S60 have three main tasks, to manage the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to ease its combustion. Then, its objective is to manage the air/fuel dosage and finally the homogeneity of the mixture, always with the target of improving combustion. If one of these three attributes is altered, the main functionality 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 provoke thoses knocking or clicking noises on your Volvo S60. The main trigger of these situations generally originates from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible obstruction will inevitably end in a malfunction of the injector.

The consequences of injector noise on Volvo S60

Now that we have analyzed the several causes for injector noise on your Volvo S60, we will end by stating the possible consequences 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 repercussions which can almost instantly become severe….
First, you risk destroying your exhaust system 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 effects 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 undoubtedly have a loss of power
Finally, you risk degrading one of your pistons or your engine. Poor combustion will almost instantly affect your cylinders or pistons and your engine may tighten.
Here are three little suggestions 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>
