It is rarely ever pleasant to experience an injector noise on your skoda octavia. It is a noise that comes up repeatedly, usually when you accelerate or your engine is idling. However, this indicator may be linked to multiple kind of trouble with your automobile injectors. It may not be anything severe, but when a continuing noise arises, you have to be sure. Especially since repairing your skoda octavia’s injectors can be expensive. That’s why our team decided to compose this article in order to support you see more clearly, learn about the different possible failures and distinguish your problem. To do this, we will first look at the normal function and usefulness of the injectors in your skoda octavia, then at the possible triggers from which an injector noise may come.
Benefits of the injectors
Injectors are a very significant element of the operation of your engine unit. They were launched to the modern cars about 20 years ago. Before their appearance, 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 ability, 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 collected from the various sensors equipping the automobile (engine temperature, acceleration level, engine speed, etc.). Their goal 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 origins of a clicking or knocking noise coming from the injectors of your skoda octavia
Listening injector noises on your skoda octavia may result from different sources, we will now center on the potential triggers of these. In most cases, 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 eliminate them. If you experience another clicking noise but it is not from your injectors, we encourage you to go through this article about clicking noise on skoda octavia to discover the cause.
The reasons for injector clicking or knocking noise skoda octavia
A clicking or knocking noise from your injectors can be explained for different reasons. In fact, the injectors of your skoda octavia have three main tasks, to control the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to ease its combustion. Then, its objective 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 tasks is altered, the main role 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 induce thoses knocking or clicking noises on your skoda octavia. The main cause of these trouble in most cases originates from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible blockage will inevitably lead to a malfunction of the injector. If after checking, this noise originates from another part of the engine of your skoda octavia, check this article for more informations.
The repercussions of injector noise on skoda octavia
Now that we have analyzed the different reasons for injector noise on your skoda octavia, we will end by stating the possible side effects 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 side effects which can promptly 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 experienced 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 surely have a loss of power
Finally, you risk degrading one of your pistons or your engine. Poor combustion will promptly harm your cylinders or pistons and your engine may tighten.
Here are three little tips to limit the risks connected 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>
