It is rarely ever relaxing to hear an injector noise on your Opel Vectra. It is a noise that happens frequently, usually when you accelerate or your engine is idling. However, this indicator may be related to multiple kind of problems with your car injectors. It may not be anything major, but when a persistent noise happens, you have to be sure. Most importantly since repairing your Opel Vectra’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 possible failures and identify your issue. To do this, we will first look at the normal functioning and usefulness of the injectors in your Opel Vectra, then at the possible causes from which an injector noise may come.injector-noise-opel-vectra

Functions of the injectors

Injectors are a very useful component of the operation of your engine motor. 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 opportunity, 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 accumulated 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 get the best possible combustion in the cylinders.

The different triggers of a clicking or knocking noise coming from the injectors of your Opel Vectra

Finding out injector noises on your Opel Vectra may result from different sources, we will now look into the potential triggers 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 adopted to stop them. If you hear another clicking noise but it is not from your injectors, we encourage you to examine this content about clicking noise on Opel Vectra to find the reason.

The reasons for injector clicking or knocking noise Opel Vectra

A clicking or knocking noise from your injectors can be explained for different reasons. Indeed, the injectors of your Opel Vectra have three main tasks, to control the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to ease its combustion. Then, its objective is to deal with the air/fuel dosage and finally the homogeneity of the mixture, always with the aim of improving combustion. If one of these three tasks is modified, the main purpose of the injectors will be disrupted and this will lead to poor combustion. This bad combustion will be a violent explosion in the cylinders because of bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will provoke thoses knocking or clicking noises on your Opel Vectra. The main reason of these situations usually originates 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 end result of injector noise on Opel Vectra

Now that we have reviewed the several causes for injector noise on your Opel Vectra, 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 effects 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 consequences felt by drivers is a severe loss of power. Indeed, if your engine is running on 3 out of 4 cylinders for example, you will obviously have a loss of power
Finally, you risk deteriorating one of your pistons or your engine. Poor combustion will fairly quickly harm your cylinders or pistons and your engine may tighten.
Here are three little suggestions 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>
