It is rarely ever relaxing to listen to an injector noise on your Vauxhall Corsa. It is a noise that arises frequently, usually when you accelerate or your engine is idling. However, this indication may be connected to several sort of trouble with your automobile injectors. It may not be anything severe, but when a persistent noise appears, you have to be sure. Most importantly since fixing your Vauxhall Corsa’s injectors can be expensive. That’s why our team chose to produce this article content in order to help you see more clearly, learn about the different conceivable failures and distinguish your trouble. To do this, we will first look at the normal functioning and usefulness of the injectors in your Vauxhall Corsa, then at the conceivable causes from which an injector noise may come.injector-noise-vauxhall-corsa

Purposes of the injectors

Injectors are a very fundamental component of the operation of your engine unit. They were brought in to the modern vehicles about 20 years ago. Before their introduction, 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 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 automobile (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 based on the injectors of your Vauxhall Corsa

Experiencing injector noises on your Vauxhall Corsa may come from different locations, we will now focus on the potential triggers of these. In general, the regular noise of a faulty injector is of the snap type. Here are the several sources of these noises and the solutions to be adopted to eliminate them. If you listen to another clicking noise but it is not from your injectors, we advise you to read this article content about clicking noise on Vauxhall Corsa to find the cause.

The reasons for injector clicking or knocking noise Vauxhall Corsa

A clicking or knocking noise from your injectors can be justified by different reasons. Indeed, the injectors of your Vauxhall Corsa have three main missions, to control the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to ease its combustion. Then, its task is to manage 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 altered, the main functionality of the injectors will be disrupted 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 Vauxhall Corsa. The main cause of these trouble in most cases comes from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible obstruction will inevitably lead to a malfunction of the injector.

The repercussions of injector noise on Vauxhall Corsa

Now that we have examined the diverse reasons for injector noise on your Vauxhall Corsa, we will end by stating the possible side 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 promptly become serious….
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 effects 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 undoubtedly have a loss of power
Finally, you risk degrading one of your pistons or your engine. Poor combustion will promptly damage your cylinders or pistons and your engine may tighten.
Here are three little tips to limit the risks connected 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 changing your diesel fuel filter regularly>
