It is rarely ever pleasurable to experience an injector noise on your Volkswagen Golf 2. It is a noise that arises continually, usually when you accelerate or your engine is idling. However, this sign may be related to several kind of trouble with your automobile injectors. It may not be anything severe, but when a persistent noise comes out, you have to be sure. Most importantly since replacing your Volkswagen Golf 2’s injectors can be costly. That’s why our team chose to produce this article in order to support you see more clearly, learn about the different plausible failures and identify your problem. To do this, we will first look at the normal functioning and usefulness of the injectors in your Volkswagen Golf 2, then at the plausible triggers from which an injector noise may come.
Purposes of the injectors
Injectors are a very fundamental element of the operation of your engine motor. They were introduced to the modern vehicles about 20 years ago. Before their appearance, 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 obtained 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 triggers of a clicking or knocking noise based on the injectors of your Volkswagen Golf 2
Discovering injector noises on your Volkswagen Golf 2 may result from different sources, we will now focus on the potential causes of these. In general, the common noise of a faulty injector is of the snap type. Here are the several origins of these noises and the solutions to be applied to prevent them. If you experience another clicking noise but it is not from your injectors, we advise you to examine this article about clicking noise on Volkswagen Golf 2 to discover the trigger.
The causes for injector clicking or knocking noise Volkswagen Golf 2
A clicking or knocking noise from your injectors can be explained for different causes. Indeed, the injectors of your Volkswagen Golf 2 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 deal with the air/fuel dosage and at last the homogeneity of the mixture, always with the objective of improving combustion. If one of these three tasks is altered, 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 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 Golf 2. The main trigger of these concerns in most cases originates from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible blockage will inevitably end in a malfunction of the injector. If after checking, this noise originates from another part of the engine of your Volkswagen Golf 2, read this article for more infos.
The end result of injector noise on Volkswagen Golf 2
Now that we have reviewed the diverse causes for injector noise on your Volkswagen Golf 2, we will end by stating the possible consequences of malfunctioning one or more of your injectors. Whether only one is blocked, or broken, or your entire fuel rail is involved, you cannot escape these repercussions which can promptly 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 repercussions noticed by drivers is a significant 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 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 linked to 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>
