It is rarely ever pleasurable to notice an injector noise on your Volkswagen Crafter 2. It is a noise that appears continually, usually when you accelerate or your engine is idling. However, this symptom may be connected to multiple sort of concerns with your car injectors. It may not be anything severe, but when a persistent noise comes out, you have to be sure. Especially since fixing your Volkswagen Crafter 2’s injectors can be costly. That’s why our team decided to produce this content page in order to help you see more clearly, learn about the different plausible failures and establish your problem. To do this, we will first look at the normal running and usefulness of the injectors in your Volkswagen Crafter 2, then at the plausible triggers from which an injector noise may come.
Functions of the injectors
Injectors are a very useful part of the operation of your engine. They were launched to the modern automobiles about 20 years ago. Before their introduction, 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 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 triggers of a clicking or knocking noise caused by the injectors of your Volkswagen Crafter 2
Finding out injector noises on your Volkswagen Crafter 2 may originate from different origins, we will now concentrate on the potential triggers of these. Generally, 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 put into practice to eliminate them. If you notice another clicking noise but it is not from your injectors, we encourage you to browse this content page about clicking noise on Volkswagen Crafter 2 to discover the cause.
The explanations for injector clicking or knocking noise Volkswagen Crafter 2
A clicking or knocking noise from your injectors can be explained for different explanations. Indeed, the injectors of your Volkswagen Crafter 2 have three main tasks, to control the vaporisation of the fuel, i.e., to convert 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 characteristics is modified, 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 as a consequence of bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will provoke thoses knocking or clicking noises on your Volkswagen Crafter 2. The main cause of these trouble generally originates from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible obstruction will inevitably cause a malfunction of the injector. If after checking, this noise originates from another part of the engine of your Volkswagen Crafter 2, check this content page for more informations.
The effects of injector noise on Volkswagen Crafter 2
Now that we have reviewed the several reasons for injector noise on your Volkswagen Crafter 2, we will end by stating the possible end result of malfunctioning one or more of your injectors. Whether only one is obstructed, or damaged, or your entire fuel rail is involved, you cannot escape these effects which can quickly 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 regular consequences felt 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 deteriorating one of your pistons or your engine. Poor combustion will quickly affect your cylinders or pistons and your engine may tighten.
Here are three little suggestions to limit the risks associated 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 swapping your diesel fuel filter regularly>
