It is never enjoyable to perceive an injector noise on your Mazda CX 30. It is a noise that appears regularly, usually when you accelerate or your engine is idling. However, this warning sign may be related to multiple sort of problems with your automobile injectors. It may not be anything major, but when a repeated noise appears, you have to be sure. Specifically since fixing your Mazda CX 30’s injectors can be expensive. That’s why our team chose to create this article in order to help you see more clearly, learn about the different possible failures and distinguish your trouble. To do this, we will first look at the normal running and usefulness of the injectors in your Mazda CX 30, then at the possible triggers from which an injector noise may come.
Purposes of the injectors
Injectors are a very vital part of the operation of your engine motor. They were introduced to the modern vehicles about 20 years ago. Before their introduction, 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 opportunity, 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 obtained from the various sensors equipping the automobile (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 causes of a clicking or knocking noise caused by the injectors of your Mazda CX 30
Hearing injector noises on your Mazda CX 30 may originate from different locations, we will now focus on the potential triggers of these. In most cases, the typical noise of a faulty injector is of the snap type. Here are the different sources of these noises and the solutions to be adopted to eliminate them. If you perceive another clicking noise but it is not from your injectors, we suggest you to examine this article about clicking noise on Mazda CX 30 to discover the trigger.
The causes for injector clicking or knocking noise Mazda CX 30
A clicking or knocking noise from your injectors can be explained for different causes. Indeed, the injectors of your Mazda CX 30 have three main missions, to control the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to ease its combustion. Then, its objective is to deal with the air/fuel dosage and finally the homogeneity of the mixture, always with the goal of improving combustion. If one of these three tasks is altered, 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 resulting from 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 30. The main trigger of these situations generally comes from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible obstruction will inevitably produce a malfunction of the injector. If after verifying, this noise comes from another part of the engine of your Mazda CX 30, check this article for more infos.
The side effects of injector noise on Mazda CX 30
Now that we have analyzed the several causes for injector noise on your Mazda CX 30, we will end by stating the possible end result of malfunctioning one or more of your injectors. Whether only one is clogged, or damaged, or your entire fuel rail is involved, you cannot escape these effects which can fairly quickly become severe….
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 regular effects experienced by drivers is a significant loss of power. Indeed, if your engine is running on 3 out of 4 cylinders for example, you will undoubtedly have a loss of power
Finally, you risk degrading one of your pistons or your engine. Poor combustion will fairly quickly damage 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 changing your diesel fuel filter regularly>
