It is never pleasant to listen an injector noise on your Opel Insignia. It is a noise that appears repeatedly, usually when you accelerate or your engine is idling. However, this warning sign may be linked to several types of complications with your car injectors. It may not be anything major, but when a continuing noise arises, you have to be sure. Especially since replacing your Opel Insignia’s injectors can be costly. That’s why our team chose to create this article content in order to help you see more clearly, learn about the different possible failures and establish your trouble. To do this, we will first look at the normal running and usefulness of the injectors in your Opel Insignia, then at the possible causes from which an injector noise may come.
Purposes of the injectors
Injectors are a very vital part of the operation of your engine motor. They were launched to the modern vehicles about 20 years ago. Before their arrival, 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 accurately (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 aim 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 reasons of a clicking or knocking noise caused by the injectors of your Opel Insignia
Experiencing injector noises on your Opel Insignia may result from different locations, we will now concentrate on 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 put into practice to eliminate them. If you listen another clicking noise but it is not from your injectors, we suggest you to examine this article content about clicking noise on Opel Insignia to locate the trigger.
The explanations for injector clicking or knocking noise Opel Insignia
A clicking or knocking noise from your injectors can be explained for different explanations. In fact, the injectors of your Opel Insignia 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 deal with 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 due to bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will trigger thoses knocking or clicking noises on your Opel Insignia. The main trigger 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 end up in a malfunction of the injector. If after verifying, this noise comes from another element of the engine of your Opel Insignia, have a look at this article content for more infos.
The effects of injector noise on Opel Insignia
Now that we have examined the different causes for injector noise on your Opel Insignia, 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 repercussions which can fairly 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 effects experienced by drivers is a severe loss of power. In fact, 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 changing your diesel fuel filter regularly>
