It is never enjoyable to notice an injector noise on your Opel Zafira Tourer. It is a noise that comes up repeatedly, usually when you accelerate or your engine is idling. However, this indication may be relating to several types of trouble with your car injectors. It may not be anything major, but when a recurrent noise arises, you have to be sure. Especially since fixing your Opel Zafira Tourer’s injectors can be costly. That’s why our team chose to create this content page in order to help 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 Tourer, then at the plausible triggers from which an injector noise may come.
Attributes of the injectors
Injectors are a very important component of the operation of your engine motor. They were introduced 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 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 origins of a clicking or knocking noise caused by the injectors of your Opel Zafira Tourer
Finding out injector noises on your Opel Zafira Tourer may come from different sources, we will now look into the potential causes of these. Generally, the usual 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 prevent them. If you notice another clicking noise but it is not from your injectors, we recommend you to examine this content page about clicking noise on Opel Zafira Tourer to find the trigger.
The causes for injector clicking or knocking noise Opel Zafira Tourer
A clicking or knocking noise from your injectors can be justified by different causes. Indeed, the injectors of your Opel Zafira Tourer have three main tasks, to control the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to facilitate its combustion. Then, its goal 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 tasks is altered, the main purpose of the injectors will be disturbed and this will lead to poor combustion. This bad combustion will be a violent explosion in the cylinders resulting from bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will induce thoses knocking or clicking noises on your Opel Zafira Tourer. The main trigger of these situations commonly comes from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible blockage will inevitably produce a malfunction of the injector.

The consequences of injector noise on Opel Zafira Tourer
Now that we have examined the different reasons for injector noise on your Opel Zafira Tourer, we will end by stating the possible side effects 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 critical….
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 regular effects experienced by drivers is a significant loss of power. Indeed, 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 fairly quickly affect your cylinders or pistons and your engine may tighten.
Here are three little recommendations to limit the risks linked 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>
