It is hardly ever relaxing to hear an injector noise on your Opel Vivaro. It is a noise that happens continually, usually when you accelerate or your engine is idling. However, this sign may be connected to different types of problems with your vehicle injectors. It may not be anything serious, but when a persistent noise appears, you have to be sure. Especially since repairing your Opel Vivaro’s injectors can be expensive. That’s why our team chose to compose this article content in order to help you see more clearly, learn about the different conceivable failures and establish your trouble. To do this, we will first look at the normal function and usefulness of the injectors in your Opel Vivaro, then at the conceivable triggers from which an injector noise may come.
Attributes of the injectors
Injectors are a very significant element 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 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 obtained from the various sensors equipping the vehicle (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 get the best possible combustion in the cylinders.
The different triggers of a clicking or knocking noise based on the injectors of your Opel Vivaro
Hearing injector noises on your Opel Vivaro may come from different locations, we will now focus on the potential triggers of these. Generally, 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 prevent them. If you hear another clicking noise but it is not from your injectors, we advise you to go through this article content about clicking noise on Opel Vivaro to find the reason.
The reasons for injector clicking or knocking noise Opel Vivaro
A clicking or knocking noise from your injectors can be justified by different reasons. In fact, the injectors of your Opel Vivaro have three main missions, to control the vaporisation of the fuel, i.e., to convert 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 aim of improving combustion. If one of these three features is altered, 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 due to bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will induce thoses knocking or clicking noises on your Opel Vivaro. The main reason of these situations in most cases originates from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible blockage will inevitably produce a malfunction of the injector. If after checking, this noise originates from another component of the engine of your Opel Vivaro, read this article content for more infos.
The effects of injector noise on Opel Vivaro
Now that we have analyzed the different reasons for injector noise on your Opel Vivaro, we will end by stating the possible end result of malfunctioning one or more of your injectors. Whether only one is obstructed, or damaged, or your entire fuel rail is involved, you cannot escape these effects which can fairly quickly become critical….
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 repercussions noticed 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 surely have a loss of power
Finally, you risk degrading one of your pistons or your engine. Poor combustion will fairly quickly affect your cylinders or pistons and your engine may tighten.
Here are three little tips 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>
