It is rarely ever pleasant to notice an injector noise on your Volkswagen Crafter. It is a noise that happens repeatedly, usually when you accelerate or your engine is idling. However, this indication may be connected to different sort of complications with your automobile injectors. It may not be anything serious, but when a frequent noise shows up, you have to be sure. Most importantly since fixing your Volkswagen Crafter’s injectors can be costly. That’s why our team decided to produce this content in order to help you see more clearly, learn about the different conceivable failures and distinguish your problem. To do this, we will first look at the normal running and usefulness of the injectors in your Volkswagen Crafter, then at the conceivable reasons from which an injector noise may come.
Benefits of the injectors
Injectors are a very significant part of the operation of your engine motor. They were released to the modern automobiles about 20 years ago. Before their arrival, more conventional carburettor-type intake systems were used, 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 accurately (quantity of fuel injected, air/fuel mixture) via the analysis of the data received 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 obtain the best possible combustion in the cylinders.
The different causes of a clicking or knocking noise based on the injectors of your Volkswagen Crafter
Listening injector noises on your Volkswagen Crafter may result from different sources, we will now focus on the potential triggers of these. In most cases, the usual noise of a faulty injector is of the snap type. Here are the different sources of these noises and the solutions to be implemented to get rid of them. If you notice another clicking noise but it is not from your injectors, we recommend you to read this content about clicking noise on Volkswagen Crafter to find the reason.
The reasons for injector clicking or knocking noise Volkswagen Crafter
A clicking or knocking noise from your injectors can be justified by different reasons. Indeed, the injectors of your Volkswagen Crafter have three main missions, to manage the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to facilitate its combustion. Then, its task is to deal with the air/fuel dosage and at last the homogeneity of the mixture, always with the aim of improving combustion. If one of these three functions is modified, the main role 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 Volkswagen Crafter. The main reason 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 Volkswagen Crafter, read this content for more infos.
The end result of injector noise on Volkswagen Crafter
Now that we have analyzed the several reasons for injector noise on your Volkswagen Crafter, we will end by stating the possible end result 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 severe….
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 basic repercussions 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 undoubtedly 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 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>
