It is rarely ever relaxing to listen an injector noise on your Opel Astra. It is a noise that comes up repeatedly, usually when you accelerate or your engine is idling. However, this sign may be relating to several kind of complications with your automobile injectors. It may not be anything severe, but when a recurrent noise comes out, you have to be sure. Specifically since replacing your Opel Astra’s injectors can be costly. That’s why our team chose to produce this content page in order to help you see more clearly, learn about the different possible failures and identify your issue. To do this, we will first look at the normal function and usefulness of the injectors in your Opel Astra, then at the possible causes from which an injector noise may come.
Attributes of the injectors
Injectors are a very important part of the operation of your engine motor. They were released to the modern automobiles 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 precisely (quantity of fuel injected, air/fuel mixture) via the analysis of the data accumulated 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 causes of a clicking or knocking noise based on the injectors of your Opel Astra
Finding out injector noises on your Opel Astra may come from different sources, we will now center on the potential triggers of these. Generally, the common noise of a faulty injector is of the snap type. Here are the several sources of these noises and the solutions to be implemented to prevent them. If you listen another clicking noise but it is not from your injectors, we recommend you to read this content page about clicking noise on Opel Astra to find the reason.
The reasons for injector clicking or knocking noise Opel Astra
A clicking or knocking noise from your injectors can be justified by different reasons. Indeed, the injectors of your Opel Astra have three main tasks, to manage the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to facilitate its combustion. Then, its task is to deal with the air/fuel dosage and at last the homogeneity of the mixture, always with the goal 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 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 Opel Astra. The main reason of these problems generally originates from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible obstruction will inevitably end in a malfunction of the injector.

The end result of injector noise on Opel Astra
Now that we have reviewed the several reasons for injector noise on your Opel Astra, we will end by stating the possible side effects of malfunctioning one or more of your injectors. Whether only one is obstructed, or broken, or your entire fuel rail is involved, you cannot escape these consequences which can almost instantly become major….
First, you risk destroying your exhaust unit 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 consequences noticed by drivers is a noticeable 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 degrading one of your pistons or your engine. Poor combustion will almost instantly affect your cylinders or pistons and your engine may tighten.
Here are three little suggestions to limit the risks relating 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 swapping your diesel fuel filter regularly>
