It is never pleasurable to perceive an injector noise on your Mazda CX 9. It is a noise that happens frequently, usually when you accelerate or your engine is idling. However, this warning sign may be relating to multiple sort of trouble with your vehicle injectors. It may not be anything severe, but when a continuing noise happens, you have to be sure. Most importantly since fixing your Mazda CX 9’s injectors can be expensive. That’s why our team chose to write this article in order to help you see more clearly, learn about the different conceivable failures and establish your issue. To do this, we will first look at the normal running and usefulness of the injectors in your Mazda CX 9, then at the conceivable causes from which an injector noise may come.
Functions of the injectors
Injectors are a very fundamental element 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 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 accurately (quantity of fuel injected, air/fuel mixture) via the analysis of the data collected 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 origins of a clicking or knocking noise coming from the injectors of your Mazda CX 9
Discovering injector noises on your Mazda CX 9 may result from different sources, we will now look into the potential triggers of these. In general, the common noise of a faulty injector is of the snap type. Here are the different origins of these noises and the solutions to be used to eliminate them. If you perceive another clicking noise but it is not from your injectors, we advise you to browse this article about clicking noise on Mazda CX 9 to locate the trigger.
The explanations for injector clicking or knocking noise Mazda CX 9
A clicking or knocking noise from your injectors can be justified by different explanations. In fact, the injectors of your Mazda CX 9 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 control the air/fuel dosage and at last the homogeneity of the mixture, always with the aim of improving combustion. If one of these three attributes is altered, the main role of the injectors will be disrupted 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 provoke thoses knocking or clicking noises on your Mazda CX 9. The main trigger of these concerns in most cases originates from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible blockage will inevitably result in a malfunction of the injector. If after checking, this noise originates from another element of the engine of your Mazda CX 9, check this article for more informations.
The effects of injector noise on Mazda CX 9
Now that we have examined the diverse causes for injector noise on your Mazda CX 9, 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 repercussions 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 repercussions noticed by drivers is a severe loss of power. In fact, if your engine is running on 3 out of 4 cylinders for example, you will undoubtedly have a loss of power
Finally, you risk deteriorating one of your pistons or your engine. Poor combustion will quickly 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 changing your diesel fuel filter regularly>
