It is never pleasant to hear an injector noise on your Vauxkhall Moka. It is a noise that comes up regularly, usually when you accelerate or your engine is idling. However, this sign may be linked to several kind of trouble with your automobile injectors. It may not be anything serious, but when a recurrent noise shows up, you have to be sure. Especially since fixing your Vauxkhall Moka’s injectors can be costly. That’s why our team chose to prepare this content in order to support you see more clearly, learn about the different conceivable failures and identify your trouble. To do this, we will first look at the normal running and usefulness of the injectors in your Vauxkhall Moka, then at the conceivable triggers from which an injector noise may come.
Benefits of the injectors
Injectors are a very useful element of the operation of your engine. They were introduced to the modern automobiles 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 precisely (quantity of fuel injected, air/fuel mixture) via the analysis of the data collected from the various sensors equipping the automobile (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 get the best possible combustion in the cylinders.
The different causes of a clicking or knocking noise caused by the injectors of your Vauxkhall Moka
Experiencing injector noises on your Vauxkhall Moka may result from different origins, we will now focus on the potential causes of these. In general, the common noise of a faulty injector is of the snap type. Here are the several origins of these noises and the solutions to be applied to stop them. If you hear another clicking noise but it is not from your injectors, we recommend you to go through this content about clicking noise on Vauxkhall Moka to find the cause.
The explanations for injector clicking or knocking noise Vauxkhall Moka
A clicking or knocking noise from your injectors can be explained for different explanations. In fact, the injectors of your Vauxkhall Moka have three main missions, to manage the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to facilitate its combustion. Then, its task 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 altered, the main purpose 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 provoke thoses knocking or clicking noises on your Vauxkhall Moka. The main cause of these concerns in most cases comes from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible blockage will inevitably end up in a malfunction of the injector. If after verifying, this noise comes from another component of the engine of your Vauxkhall Moka, read this content for more informations.
The repercussions of injector noise on Vauxkhall Moka
Now that we have examined the diverse causes for injector noise on your Vauxkhall Moka, we will end by stating the possible end result of malfunctioning one or more of your injectors. Whether only one is blocked, or broken, or your entire fuel rail is involved, you cannot escape these consequences which can quickly become considerable….
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 common effects noticed by drivers is a noticeable 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 quickly harm your cylinders or pistons and your engine may tighten.
Here are three little tips to limit the risks relating 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>
