It is never enjoyable to notice an injector noise on your Opel Mokka X. It is a noise that happens frequently, usually when you accelerate or your engine is idling. However, this indicator may be relating to several types of problems with your vehicle injectors. It may not be anything severe, but when a recurrent noise shows up, you have to be sure. Specifically since replacing your Opel Mokka X’s injectors can be costly. That’s why our team decided to write this content page in order to support you see more clearly, learn about the different conceivable failures and establish your issue. To do this, we will first look at the normal functioning and usefulness of the injectors in your Opel Mokka X, then at the conceivable reasons from which an injector noise may come.
Benefits of the injectors
Injectors are a very important 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 opportunity, 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 received from the various sensors equipping the vehicle (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 Mokka X
Experiencing injector noises on your Opel Mokka X may originate from different origins, we will now look into the potential causes of these. In most cases, 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 implemented to prevent them. If you notice another clicking noise but it is not from your injectors, we recommend you to browse this content page about clicking noise on Opel Mokka X to discover the reason.
The reasons for injector clicking or knocking noise Opel Mokka X
A clicking or knocking noise from your injectors can be justified by different reasons. Indeed, the injectors of your Opel Mokka X have three main tasks, to manage the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to ease its combustion. Then, its goal is to manage the air/fuel dosage and at last the homogeneity of the mixture, always with the objective of improving combustion. If one of these three features 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 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 Mokka X. The main reason of these problems commonly comes from a particle that gets into the injectors. The accuracy 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 component of the engine of your Opel Mokka X, have a look at this content page for more informations.
The repercussions of injector noise on Opel Mokka X
Now that we have analyzed the different reasons for injector noise on your Opel Mokka X, 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 side effects which can 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 known effects noticed by drivers is a noticeable 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 quickly harm your cylinders or pistons and your engine may tighten.
Here are three little recommendations 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>
