It is rarely ever pleasurable to hear an injector noise on your Opel Zafira. It is a noise that arises continually, usually when you accelerate or your engine is idling. However, this symptom may be related to multiple sort of problems with your car injectors. It may not be anything major, but when a persistent noise comes out, you have to be sure. Especially since fixing your Opel Zafira’s injectors can be expensive. That’s why our team chose to create this content page in order to support you see more clearly, learn about the different conceivable failures and determine your issue. To do this, we will first look at the normal function and usefulness of the injectors in your Opel Zafira, then at the conceivable triggers from which an injector noise may come.
Attributes of the injectors
Injectors are a very fundamental part of the operation of your engine motor. They were introduced to the modern vehicles 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 possibility, 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 obtained from the various sensors equipping the car (engine temperature, acceleration level, engine speed, etc.). Their goal 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 origins of a clicking or knocking noise based on the injectors of your Opel Zafira
Discovering injector noises on your Opel Zafira may result from different origins, we will now concentrate on the potential causes of these. Generally, the typical noise of a faulty injector is of the snap type. Here are the different origins of these noises and the solutions to be adopted to get rid of them. If you hear another clicking noise but it is not from your injectors, we advise you to go through this content page about clicking noise on Opel Zafira to locate the cause.
The explanations for injector clicking or knocking noise Opel Zafira
A clicking or knocking noise from your injectors can be justified by different explanations. In fact, the injectors of your Opel Zafira have three main tasks, to manage the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to ease its combustion. Then, its mission is to deal with the air/fuel dosage and at last the homogeneity of the mixture, always with the objective 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 trigger thoses knocking or clicking noises on your Opel Zafira. The main cause of these situations usually comes from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible obstruction will inevitably cause a malfunction of the injector. If after verifying, this noise comes from another element of the engine of your Opel Zafira, check this content page for more informations.
The end result of injector noise on Opel Zafira
Now that we have analyzed the several reasons for injector noise on your Opel Zafira, we will end by stating the possible 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 repercussions which can almost instantly become major….
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 regular consequences noticed by drivers is a noticeable 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 deteriorating one of your pistons or your engine. Poor combustion will almost instantly damage your cylinders or pistons and your engine may tighten.
Here are three little tips 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 swapping your diesel fuel filter regularly>
