It is rarely ever pleasant to acknowledge an injector noise on your Opel Antara. It is a noise that arises regularly, usually when you accelerate or your engine is idling. However, this indication may be linked to different kind of problems with your vehicle injectors. It may not be anything major, but when a recurrent noise happens, you have to be sure. Especially since repairing your Opel Antara’s injectors can be costly. That’s why our team chose to compose this article in order to help you see more clearly, learn about the different plausible failures and distinguish your problem. To do this, we will first look at the normal function and usefulness of the injectors in your Opel Antara, then at the plausible reasons from which an injector noise may come.
Functions of the injectors
Injectors are a very fundamental component of the operation of your engine motor. They were launched to the modern cars about 20 years ago. Before their introduction, 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 accumulated from the various sensors equipping the vehicle (engine temperature, acceleration level, engine speed, etc.). Their purpose 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 Opel Antara
Listening injector noises on your Opel Antara may result from different locations, we will now focus on the potential causes of these. Generally, the regular noise of a faulty injector is of the snap type. Here are the several sources of these noises and the solutions to be used to get rid of them. If you acknowledge another clicking noise but it is not from your injectors, we encourage you to examine this article about clicking noise on Opel Antara to find the trigger.
The reasons for injector clicking or knocking noise Opel Antara
A clicking or knocking noise from your injectors can be justified by different reasons. In fact, the injectors of your Opel Antara have three main tasks, to control the vaporisation of the fuel, i.e., to transform 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 modified, 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 Opel Antara. The main trigger of these situations 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 verifying, this noise comes from another part of the engine of your Opel Antara, have a look at this article for more infos.
The end result of injector noise on Opel Antara
Now that we have reviewed the several reasons for injector noise on your Opel Antara, 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 considerable….
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 basic effects experienced by drivers is a serious 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 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 suggestions 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 changing your diesel fuel filter regularly>
