It is never enjoyable to experience an injector noise on your Volkswagen Transporter 6. It is a noise that happens repeatedly, usually when you accelerate or your engine is idling. However, this indication may be linked to multiple types of concerns with your car injectors. It may not be anything major, but when a frequent noise happens, you have to be sure. Specifically since repairing your Volkswagen Transporter 6’s injectors can be expensive. That’s why our team decided to produce this article content in order to help you see more clearly, learn about the different plausible failures and distinguish your problem. To do this, we will first look at the normal functioning and usefulness of the injectors in your Volkswagen Transporter 6, then at the plausible triggers from which an injector noise may come.
Functions of the injectors
Injectors are a very fundamental component of the operation of your engine. They were introduced to the modern vehicles 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 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 received 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 reasons of a clicking or knocking noise coming from the injectors of your Volkswagen Transporter 6
Hearing injector noises on your Volkswagen Transporter 6 may originate 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 different origins of these noises and the solutions to be applied to stop them. If you experience another clicking noise but it is not from your injectors, we encourage you to browse this article content about clicking noise on Volkswagen Transporter 6 to find the cause.
The reasons for injector clicking or knocking noise Volkswagen Transporter 6
A clicking or knocking noise from your injectors can be justified by different reasons. Indeed, the injectors of your Volkswagen Transporter 6 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 goal is to control the air/fuel dosage and at last the homogeneity of the mixture, always with the target of improving combustion. If one of these three attributes is altered, 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 because 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 Transporter 6. The main cause of these trouble commonly originates from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible blockage will inevitably produce a malfunction of the injector. If after checking, this noise originates from another element of the engine of your Volkswagen Transporter 6, check this article content for more infos.
The end result of injector noise on Volkswagen Transporter 6
Now that we have reviewed the different reasons for injector noise on your Volkswagen Transporter 6, we will end by stating the possible side 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 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 regular 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 fairly quickly affect your cylinders or pistons and your engine may tighten.
Here are three little tips 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 swapping your diesel fuel filter regularly>
