It is hardly ever enjoyable to experience an injector noise on your volvo v70. It is a noise that happens regularly, usually when you accelerate or your engine is idling. However, this indicator may be related to different kind of concerns with your car injectors. It may not be anything severe, but when a persistent noise happens, you have to be sure. Specifically since replacing your volvo v70’s injectors can be costly. That’s why our team chose to compose this article in order to support you see more clearly, learn about the different possible failures and distinguish your issue. To do this, we will first look at the normal running and usefulness of the injectors in your volvo v70, then at the possible causes from which an injector noise may come.
Attributes of the injectors
Injectors are a very important component of the operation of your engine. They were launched to the modern vehicles about 20 years ago. Before their appearance, 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 obtained 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 get the best possible combustion in the cylinders.
The different triggers of a clicking or knocking noise coming from the injectors of your volvo v70
Experiencing injector noises on your volvo v70 may come from different sources, we will now look into the potential causes of these. In most cases, the usual noise of a faulty injector is of the snap type. Here are the several sources of these noises and the solutions to be adopted to prevent them. If you experience another clicking noise but it is not from your injectors, we recommend you to read this article about clicking noise on volvo v70 to find the trigger.
The reasons for injector clicking or knocking noise volvo v70
A clicking or knocking noise from your injectors can be justified by different reasons. In fact, the injectors of your volvo v70 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 purpose of the injectors will be disturbed and this will lead to poor combustion. This bad combustion will be a violent explosion in the cylinders as a consequence 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 v70. The main trigger of these concerns commonly originates from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible obstruction will inevitably produce a malfunction of the injector.

The effects of injector noise on volvo v70
Now that we have analyzed the several causes for injector noise on your volvo v70, we will end by stating the possible 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 side effects which can promptly become critical….
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 repercussions experienced by drivers is a significant loss of power. In fact, if your engine is running on 3 out of 4 cylinders for example, you will surely have a loss of power
Finally, you risk deteriorating one of your pistons or your engine. Poor combustion will promptly harm your cylinders or pistons and your engine may tighten.
Here are three little tips to limit the risks relating 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>
