It is rarely ever enjoyable to hear an injector noise on your volvo v90. It is a noise that arises continually, usually when you accelerate or your engine is idling. However, this warning sign may be related to different types of problems with your automobile injectors. It may not be anything severe, but when a repeated noise happens, you have to be sure. Most importantly since repairing your volvo v90’s injectors can be costly. That’s why our team chose to compose this content in order to support you see more clearly, learn about the different possible failures and identify your issue. To do this, we will first look at the normal functioning and usefulness of the injectors in your volvo v90, then at the possible triggers from which an injector noise may come.
Functions of the injectors
Injectors are a very useful component of the operation of your engine. They were brought in 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 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 compiled 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 reasons of a clicking or knocking noise caused by the injectors of your volvo v90
Discovering injector noises on your volvo v90 may result from different origins, we will now concentrate on the potential triggers of these. In general, the usual noise of a faulty injector is of the snap type. Here are the several origins of these noises and the solutions to be adopted to stop them. If you hear another clicking noise but it is not from your injectors, we encourage you to go through this content about clicking noise on volvo v90 to locate the trigger.
The causes for injector clicking or knocking noise volvo v90
A clicking or knocking noise from your injectors can be explained for different causes. Indeed, the injectors of your volvo v90 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 objective of improving combustion. If one of these three functions 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 due to bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will induce thoses knocking or clicking noises on your volvo v90. The main trigger of these problems in most cases originates from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible obstruction will inevitably lead to a malfunction of the injector. If after checking, this noise originates from another element of the engine of your volvo v90, read this content for more infos.
The end result of injector noise on volvo v90
Now that we have analyzed the several reasons for injector noise on your volvo v90, we will end by stating the possible side effects of malfunctioning one or more of your injectors. Whether only one is blocked, or damaged, or your entire fuel rail is involved, you cannot escape these effects which can almost instantly become considerable….
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 experienced by drivers is a serious loss of power. Indeed, if your engine is running on 3 out of 4 cylinders for example, you will obviously 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 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 swapping your diesel fuel filter regularly>
