It is never enjoyable to perceive an injector noise on your Volkswagen Transporter 5. It is a noise that arises continually, usually when you accelerate or your engine is idling. However, this indicator may be linked to several types of complications with your automobile injectors. It may not be anything serious, but when a recurrent noise appears, you have to be sure. Specifically since repairing your Volkswagen Transporter 5’s injectors can be expensive. That’s why our team chose to write this content page in order to help you see more clearly, learn about the different conceivable failures and establish your problem. To do this, we will first look at the normal function and usefulness of the injectors in your Volkswagen Transporter 5, then at the conceivable causes from which an injector noise may come.
Benefits of the injectors
Injectors are a very fundamental element of the operation of your engine unit. They were introduced to the modern cars about 20 years ago. Before their introduction, 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 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 compiled from the various sensors equipping the automobile (engine temperature, acceleration level, engine speed, etc.). Their objective 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 based on the injectors of your Volkswagen Transporter 5
Discovering injector noises on your Volkswagen Transporter 5 may originate from different sources, we will now concentrate on the potential causes of these. In general, the regular noise of a faulty injector is of the snap type. Here are the several origins of these noises and the solutions to be adopted to get rid of them. If you perceive another clicking noise but it is not from your injectors, we recommend you to examine this content page about clicking noise on Volkswagen Transporter 5 to discover the cause.
The causes for injector clicking or knocking noise Volkswagen Transporter 5
A clicking or knocking noise from your injectors can be justified by different causes. In fact, the injectors of your Volkswagen Transporter 5 have three main tasks, to manage the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to ease its combustion. Then, its mission is to deal with the air/fuel dosage and finally the homogeneity of the mixture, always with the goal of improving combustion. If one of these three attributes is altered, the main purpose of the injectors will be disturbed and this will lead to poor combustion. This bad combustion will be a violent explosion in the cylinders due to bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will trigger thoses knocking or clicking noises on your Volkswagen Transporter 5. The main cause of these trouble usually originates from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible blockage will inevitably cause a malfunction of the injector. If after verifying, this noise originates from another element of the engine of your Volkswagen Transporter 5, have a look at this content page for more infos.
The side effects of injector noise on Volkswagen Transporter 5
Now that we have examined the several reasons for injector noise on your Volkswagen Transporter 5, we will end by stating the possible consequences of malfunctioning one or more of your injectors. Whether only one is clogged, or broken, or your entire fuel rail is involved, you cannot escape these side effects which can promptly become considerable….
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 felt by drivers is a distinctive loss of power. In fact, if your engine is running on 3 out of 4 cylinders for example, you will obviously have a loss of power
Finally, you risk degrading one of your pistons or your engine. Poor combustion will promptly affect your cylinders or pistons and your engine may tighten.
Here are three little recommendations 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>
