It is hardly ever pleasurable to experience an injector noise on your Mazda 2. It is a noise that comes up repeatedly, usually when you accelerate or your engine is idling. However, this indication may be related to several kind of concerns with your automobile injectors. It may not be anything severe, but when a continuing noise shows up, you have to be sure. Especially since repairing your Mazda 2’s injectors can be expensive. That’s why our team chose to create this content in order to help you see more clearly, learn about the different possible failures and distinguish your issue. To do this, we will first look at the normal function and usefulness of the injectors in your Mazda 2, then at the possible triggers from which an injector noise may come.
Benefits of the injectors
Injectors are a very useful part of the operation of your engine unit. They were brought in to the modern automobiles about 20 years ago. Before their introduction, 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 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 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 triggers of a clicking or knocking noise caused by the injectors of your Mazda 2
Finding out injector noises on your Mazda 2 may originate from different origins, we will now center on the potential causes of these. In most cases, the usual noise of a faulty injector is of the snap type. Here are the different sources of these noises and the solutions to be implemented to prevent them. If you experience another clicking noise but it is not from your injectors, we recommend you to examine this content about clicking noise on Mazda 2 to discover the trigger.
The explanations for injector clicking or knocking noise Mazda 2
A clicking or knocking noise from your injectors can be explained for different explanations. Indeed, the injectors of your Mazda 2 have three main tasks, to control the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to ease its combustion. Then, its task is to manage the air/fuel dosage and finally the homogeneity of the mixture, always with the target 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 as a consequence 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 2. The main trigger of these concerns commonly comes from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible obstruction will inevitably end in a malfunction of the injector. If after checking, this noise comes from another part of the engine of your Mazda 2, have a look at this content for more informations.
The consequences of injector noise on Mazda 2
Now that we have reviewed the several reasons for injector noise on your Mazda 2, we will end by stating the possible consequences of malfunctioning one or more of your injectors. Whether only one is clogged, or broken, or your entire fuel rail is involved, you cannot escape these side effects which can fairly quickly 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 experienced by drivers is a noticeable 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 fairly quickly harm your cylinders or pistons and your engine may tighten.
Here are three little recommendations to limit the risks linked 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>
