It is rarely ever pleasant to hear an injector noise on your Opel Zafira 3. It is a noise that happens regularly, usually when you accelerate or your engine is idling. However, this indication may be related to different kind of problems with your automobile injectors. It may not be anything major, but when a recurrent noise appears, you have to be sure. Especially since repairing your Opel Zafira 3’s injectors can be expensive. That’s why our team chose to create this content in order to support you see more clearly, learn about the different plausible failures and determine your problem. To do this, we will first look at the normal functioning and usefulness of the injectors in your Opel Zafira 3, then at the plausible causes from which an injector noise may come.
Purposes of the injectors
Injectors are a very vital component of the operation of your engine. They were released to the modern automobiles 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 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 collected from the various sensors equipping the automobile (engine temperature, acceleration level, engine speed, etc.). Their aim 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 causes of a clicking or knocking noise coming from the injectors of your Opel Zafira 3
Experiencing injector noises on your Opel Zafira 3 may come from different origins, we will now concentrate on the potential causes of these. In most cases, the typical noise of a faulty injector is of the snap type. Here are the different sources of these noises and the solutions to be applied to get rid of them. If you hear another clicking noise but it is not from your injectors, we encourage you to browse this content about clicking noise on Opel Zafira 3 to discover the trigger.
The causes for injector clicking or knocking noise Opel Zafira 3
A clicking or knocking noise from your injectors can be explained for different causes. In fact, the injectors of your Opel Zafira 3 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 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 functions is modified, 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 due to bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will trigger thoses knocking or clicking noises on your Opel Zafira 3. The main trigger of these trouble usually originates from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible obstruction will inevitably produce a malfunction of the injector. If after verifying, this noise originates from another part of the engine of your Opel Zafira 3, browse this content for more infos.
The effects of injector noise on Opel Zafira 3
Now that we have analyzed the diverse causes for injector noise on your Opel Zafira 3, we will end by stating the possible 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 side effects which can almost instantly become severe….
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 felt by drivers is a significant loss of power. In fact, if your engine is running on 3 out of 4 cylinders for example, you will inevitably 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 recommendations 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>
