It is never relaxing to listen to an injector noise on your Mazda CX 3. It is a noise that happens regularly, usually when you accelerate or your engine is idling. However, this indication may be connected to different sort of trouble with your automobile injectors. It may not be anything major, but when a frequent noise shows up, you have to be sure. Most importantly since repairing your Mazda CX 3’s injectors can be costly. That’s why our team decided to compose this content page in order to help you see more clearly, learn about the different plausible failures and identify your problem. To do this, we will first look at the normal running and usefulness of the injectors in your Mazda CX 3, then at the plausible reasons from which an injector noise may come.
Purposes of the injectors
Injectors are a very important part of the operation of your engine. They were launched to the modern vehicles about 20 years ago. Before their arrival, more conventional carburettor-type intake systems were employed, 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 accumulated from the various sensors equipping the automobile (engine temperature, acceleration level, engine speed, etc.). Their objective 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 based on the injectors of your Mazda CX 3
Discovering injector noises on your Mazda CX 3 may result from different sources, we will now center on the potential causes of these. In most cases, the typical noise of a faulty injector is of the snap type. Here are the different origins of these noises and the solutions to be implemented to stop them. If you listen to another clicking noise but it is not from your injectors, we encourage you to browse this content page about clicking noise on Mazda CX 3 to locate the trigger.
The reasons for injector clicking or knocking noise Mazda CX 3
A clicking or knocking noise from your injectors can be explained for different reasons. Indeed, the injectors of your Mazda CX 3 have three main missions, to manage the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to ease its combustion. Then, its goal is to control 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 role 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 induce thoses knocking or clicking noises on your Mazda CX 3. The main trigger of these concerns usually originates 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 checking, this noise originates from another part of the engine of your Mazda CX 3, check this content page for more informations.
The end result of injector noise on Mazda CX 3
Now that we have examined the different causes for injector noise on your Mazda CX 3, we will end by stating the possible consequences 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 repercussions which can promptly become considerable….
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 basic repercussions 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 promptly harm 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>
