It is rarely ever enjoyable to notice an injector noise on your Volkswagen Touran. It is a noise that happens frequently, usually when you accelerate or your engine is idling. However, this symptom may be related to several kind of trouble with your automobile injectors. It may not be anything major, but when a continuing noise shows up, you have to be sure. Most importantly since fixing your Volkswagen Touran’s injectors can be costly. That’s why our team decided to create this content page in order to help you see more clearly, learn about the different conceivable failures and establish your trouble. To do this, we will first look at the normal running and usefulness of the injectors in your Volkswagen Touran, then at the conceivable reasons from which an injector noise may come.
Purposes of the injectors
Injectors are a very important component of the operation of your engine unit. They were introduced to the modern vehicles 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 ability, 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 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 obtain the best possible combustion in the cylinders.
The different causes of a clicking or knocking noise caused by the injectors of your Volkswagen Touran
Discovering injector noises on your Volkswagen Touran may come from different origins, we will now concentrate 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 applied to eliminate them. If you notice another clicking noise but it is not from your injectors, we suggest you to examine this content page about clicking noise on Volkswagen Touran to find the trigger.
The reasons for injector clicking or knocking noise Volkswagen Touran
A clicking or knocking noise from your injectors can be explained for different reasons. Indeed, the injectors of your Volkswagen Touran have three main missions, to control the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to facilitate its combustion. Then, its mission 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 characteristics is altered, 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 induce thoses knocking or clicking noises on your Volkswagen Touran. The main trigger 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 result in a malfunction of the injector. If after checking, this noise originates from another component of the engine of your Volkswagen Touran, have a look at this content page for more infos.
The end result of injector noise on Volkswagen Touran
Now that we have examined the different causes for injector noise on your Volkswagen Touran, we will end by stating the possible consequences 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 side effects which can almost instantly become serious….
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 known consequences noticed by drivers is a severe 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 almost instantly harm 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>
