It is hardly ever pleasurable to notice an injector noise on your volvo v40. It is a noise that comes up regularly, usually when you accelerate or your engine is idling. However, this warning sign may be linked to different sort of concerns with your car injectors. It may not be anything serious, but when a repeated noise comes out, you have to be sure. Specifically since replacing your volvo v40’s injectors can be costly. That’s why our team decided to write this content page 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 running and usefulness of the injectors in your volvo v40, then at the possible reasons from which an injector noise may come.
Benefits of the injectors
Injectors are a very vital part 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 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 car (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 causes of a clicking or knocking noise caused by the injectors of your volvo v40
Hearing injector noises on your volvo v40 may originate from different origins, we will now center on the potential causes of these. In most cases, the common noise of a faulty injector is of the snap type. Here are the several sources of these noises and the solutions to be used to eliminate them. If you notice another clicking noise but it is not from your injectors, we encourage you to read this content page about clicking noise on volvo v40 to find the reason.
The reasons for injector clicking or knocking noise volvo v40
A clicking or knocking noise from your injectors can be justified by different reasons. Indeed, the injectors of your volvo v40 have three main missions, to control the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to ease its combustion. Then, its task is to deal with the air/fuel dosage and at last the homogeneity of the mixture, always with the goal of improving combustion. If one of these three tasks 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 as a consequence of bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will trigger thoses knocking or clicking noises on your volvo v40. The main reason of these situations commonly originates from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible blockage will inevitably cause a malfunction of the injector.

The consequences of injector noise on volvo v40
Now that we have examined the different causes for injector noise on your volvo v40, 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 promptly 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 common consequences felt by drivers is a severe loss of power. Indeed, 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 damage your cylinders or pistons and your engine may tighten.
Here are three little suggestions to limit the risks connected 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 changing your diesel fuel filter regularly>
