It is never pleasurable to hear an injector noise on your Mazda Mx5. It is a noise that happens frequently, usually when you accelerate or your engine is idling. However, this indication may be related to multiple sort of concerns with your car injectors. It may not be anything severe, but when a persistent noise arises, you have to be sure. Most importantly since fixing your Mazda Mx5’s injectors can be expensive. That’s why our team chose to prepare this content in order to support you see more clearly, learn about the different possible failures and establish your problem. To do this, we will first look at the normal function and usefulness of the injectors in your Mazda Mx5, then at the possible causes from which an injector noise may come.
Purposes of the injectors
Injectors are a very significant part of the operation of your engine. They were brought in 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 possibility, 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 obtained from the various sensors equipping the car (engine temperature, acceleration level, engine speed, etc.). Their goal 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 triggers of a clicking or knocking noise caused by the injectors of your Mazda Mx5
Experiencing injector noises on your Mazda Mx5 may come from different locations, we will now look into the potential triggers of these. Generally, the typical noise of a faulty injector is of the snap type. Here are the several origins of these noises and the solutions to be used to prevent them. If you hear another clicking noise but it is not from your injectors, we suggest you to browse this content about clicking noise on Mazda Mx5 to discover the trigger.
The causes for injector clicking or knocking noise Mazda Mx5
A clicking or knocking noise from your injectors can be explained for different causes. Indeed, the injectors of your Mazda Mx5 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 mission is to control the air/fuel dosage and finally the homogeneity of the mixture, always with the aim of improving combustion. If one of these three characteristics 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 as a consequence of bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will trigger thoses knocking or clicking noises on your Mazda Mx5. The main trigger of these situations 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 lead to a malfunction of the injector. If after verifying, this noise comes from another part of the engine of your Mazda Mx5, read this content for more informations.
The end result of injector noise on Mazda Mx5
Now that we have examined the different reasons for injector noise on your Mazda Mx5, we will end by stating the possible effects 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 side effects which can promptly become critical….
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 known effects felt by drivers is a significant loss of power. Indeed, if your engine is running on 3 out of 4 cylinders for example, you will surely have a loss of power
Finally, you risk deteriorating one of your pistons or your engine. Poor combustion will promptly affect your cylinders or pistons and your engine may tighten.
Here are three little suggestions to limit the risks connected with 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>
