It is hardly ever enjoyable to listen an injector noise on your volvo xc70. It is a noise that comes up repeatedly, usually when you accelerate or your engine is idling. However, this warning sign may be linked to several sort of trouble with your automobile injectors. It may not be anything severe, but when a frequent noise appears, you have to be sure. Specifically since fixing your volvo xc70’s injectors can be costly. That’s why our team chose to prepare this article 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 xc70, then at the possible triggers from which an injector noise may come.
Functions of the injectors
Injectors are a very important element of the operation of your engine unit. They were released to the modern automobiles 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 ability, 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 purpose 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 origins of a clicking or knocking noise based on the injectors of your volvo xc70
Listening injector noises on your volvo xc70 may result from different locations, we will now focus on the potential causes of these. Generally, 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 implemented to stop them. If you listen another clicking noise but it is not from your injectors, we encourage you to go through this article about clicking noise on volvo xc70 to discover the reason.
The causes for injector clicking or knocking noise volvo xc70
A clicking or knocking noise from your injectors can be explained for different causes. Indeed, the injectors of your volvo xc70 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 attributes is modified, the main purpose of the injectors will be disrupted 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 trigger thoses knocking or clicking noises on your volvo xc70. The main reason of these concerns usually originates from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible obstruction will inevitably lead to a malfunction of the injector. If after verifying, this noise originates from another part of the engine of your volvo xc70, check this article for more informations.
The effects of injector noise on volvo xc70
Now that we have reviewed the several reasons for injector noise on your volvo xc70, we will end by stating the possible side effects of malfunctioning one or more of your injectors. Whether only one is clogged, or damaged, or your entire fuel rail is involved, you cannot escape these effects which can fairly quickly become major….
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 basic repercussions noticed by drivers is a noticeable loss of power. Indeed, if your engine is running on 3 out of 4 cylinders for example, you will inevitably have a loss of power
Finally, you risk deteriorating one of your pistons or your engine. Poor combustion will fairly quickly damage 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>
