It is never pleasurable to listen an injector noise on your Opel Corsa. It is a noise that arises frequently, usually when you accelerate or your engine is idling. However, this indicator may be linked to different types of trouble with your car injectors. It may not be anything severe, but when a recurrent noise arises, you have to be sure. Especially since replacing your Opel Corsa’s injectors can be costly. That’s why our team chose to produce this article content in order to help you see more clearly, learn about the different possible failures and distinguish your issue. To do this, we will first look at the normal running and usefulness of the injectors in your Opel Corsa, then at the possible reasons from which an injector noise may come.
Attributes of the injectors
Injectors are a very fundamental element of the operation of your engine motor. They were brought in to the modern cars about 20 years ago. Before their arrival, 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 possibility, 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 collected from the various sensors equipping the car (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 coming from the injectors of your Opel Corsa
Experiencing injector noises on your Opel Corsa may originate from different sources, we will now look into the potential causes of these. In most cases, the usual noise of a faulty injector is of the snap type. Here are the different origins of these noises and the solutions to be implemented to stop them. If you listen another clicking noise but it is not from your injectors, we suggest you to go through this article content about clicking noise on Opel Corsa to discover the cause.
The explanations for injector clicking or knocking noise Opel Corsa
A clicking or knocking noise from your injectors can be justified by different explanations. Indeed, the injectors of your Opel Corsa have three main tasks, to control the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to ease its combustion. Then, its goal is to control the air/fuel dosage and finally the homogeneity of the mixture, always with the target of improving combustion. If one of these three features is modified, the main functionality 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 Opel Corsa. The main cause of these trouble usually comes 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 comes from another element of the engine of your Opel Corsa, have a look at this article content for more informations.
The side effects of injector noise on Opel Corsa
Now that we have reviewed the several causes for injector noise on your Opel Corsa, we will end by stating the possible end result of malfunctioning one or more of your injectors. Whether only one is clogged, or damaged, or your entire fuel rail is involved, you cannot escape these consequences which can fairly quickly become serious….
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 known consequences felt by drivers is a severe 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 deteriorating one of your pistons or your engine. Poor combustion will fairly quickly damage your cylinders or pistons and your engine may tighten.
Here are three little tips to limit the risks associated 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>
