It is never relaxing to acknowledge an injector noise on your Opel Meriva. It is a noise that arises continually, usually when you accelerate or your engine is idling. However, this indication may be linked to multiple types of concerns with your automobile injectors. It may not be anything severe, but when a persistent noise appears, you have to be sure. Specifically since repairing your Opel Meriva’s injectors can be costly. That’s why our team chose to create this content in order to support you see more clearly, learn about the different conceivable failures and establish your trouble. To do this, we will first look at the normal functioning and usefulness of the injectors in your Opel Meriva, then at the conceivable causes from which an injector noise may come.injector-noise-opel-meriva

Functions of the injectors

Injectors are a very useful element of the operation of your engine. They were brought in to the modern cars about 20 years ago. Before their appearance, 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 precisely (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 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 coming from the injectors of your Opel Meriva

Discovering injector noises on your Opel Meriva may originate from different locations, 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 used to get rid of them. If you acknowledge another clicking noise but it is not from your injectors, we advise you to examine this content about clicking noise on Opel Meriva to discover the trigger.

The explanations for injector clicking or knocking noise Opel Meriva

A clicking or knocking noise from your injectors can be explained for different explanations. Indeed, the injectors of your Opel Meriva have three main tasks, to manage the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to facilitate its combustion. Then, its mission is to control the air/fuel dosage and at last the homogeneity of the mixture, always with the target of improving combustion. If one of these three tasks is altered, 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 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 Meriva. The main trigger of these situations in most cases comes from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible blockage will inevitably end up in a malfunction of the injector.

The repercussions of injector noise on Opel Meriva

Now that we have analyzed the several reasons for injector noise on your Opel Meriva, we will end by stating the possible side effects of malfunctioning one or more of your injectors. Whether only one is clogged, or broken, or your entire fuel rail is involved, you cannot escape these side effects which can quickly 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 common consequences noticed 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 quickly damage your cylinders or pistons and your engine may tighten.
Here are three little suggestions 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>
