It is hardly ever relaxing to hear an injector noise on your Mazda 3. It is a noise that appears continually, usually when you accelerate or your engine is idling. However, this indication may be linked to different types of complications with your car injectors. It may not be anything serious, but when a frequent noise arises, you have to be sure. Specifically since fixing your Mazda 3’s injectors can be expensive. That’s why our team chose to prepare this article content in order to support you see more clearly, learn about the different plausible failures and establish your issue. To do this, we will first look at the normal functioning and usefulness of the injectors in your Mazda 3, then at the plausible reasons from which an injector noise may come.
Attributes of the injectors
Injectors are a very vital component of the operation of your engine unit. They were released 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 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 compiled 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 origins of a clicking or knocking noise based on the injectors of your Mazda 3
Hearing injector noises on your Mazda 3 may originate from different origins, 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 several sources of these noises and the solutions to be used to eliminate them. If you hear another clicking noise but it is not from your injectors, we recommend you to go through this article content about clicking noise on Mazda 3 to find the trigger.
The causes for injector clicking or knocking noise Mazda 3
A clicking or knocking noise from your injectors can be justified by different causes. Indeed, the injectors of your Mazda 3 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 goal is to control the air/fuel dosage and finally the homogeneity of the mixture, always with the objective of improving combustion. If one of these three characteristics is altered, the main functionality of the injectors will be disturbed and this will lead to poor combustion. This bad combustion will be a violent explosion in the cylinders because of bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will induce thoses knocking or clicking noises on your Mazda 3. The main trigger of these trouble commonly originates from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible obstruction will inevitably lead to a malfunction of the injector. If after verifying, this noise originates from another part of the engine of your Mazda 3, read this article content for more infos.
The end result of injector noise on Mazda 3
Now that we have analyzed the diverse causes for injector noise on your Mazda 3, 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 repercussions which can almost instantly become major….
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 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 inevitably have a loss of power
Finally, you risk deteriorating one of your pistons or your engine. Poor combustion will almost instantly harm your cylinders or pistons and your engine may tighten.
Here are three little tips to limit the risks connected 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>
