It is hardly ever pleasant to listen to an injector noise on your Mazda 5. It is a noise that comes up continually, usually when you accelerate or your engine is idling. However, this symptom may be related to different kind of problems with your vehicle injectors. It may not be anything major, but when a persistent noise happens, you have to be sure. Most importantly since replacing your Mazda 5’s injectors can be costly. That’s why our team chose to prepare this content page in order to support you see more clearly, learn about the different conceivable failures and establish your issue. To do this, we will first look at the normal function and usefulness of the injectors in your Mazda 5, then at the conceivable reasons from which an injector noise may come.
Purposes of the injectors
Injectors are a very useful element of the operation of your engine unit. They were launched to the modern cars 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 possibility, 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 purpose is therefore to inject under high pressure a precise quantity of an air/fuel mixture at a perfect timing to get the best possible combustion in the cylinders.
The different causes of a clicking or knocking noise based on the injectors of your Mazda 5
Listening injector noises on your Mazda 5 may originate from different origins, we will now concentrate 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 applied to stop them. If you listen to another clicking noise but it is not from your injectors, we recommend you to examine this content page about clicking noise on Mazda 5 to locate the reason.
The causes for injector clicking or knocking noise Mazda 5
A clicking or knocking noise from your injectors can be justified by different causes. In fact, the injectors of your Mazda 5 have three main missions, to manage the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to facilitate its combustion. Then, its objective is to deal with the air/fuel dosage and at last the homogeneity of the mixture, always with the target of improving combustion. If one of these three functions is altered, the main purpose 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 trigger thoses knocking or clicking noises on your Mazda 5. The main reason of these trouble 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 end in a malfunction of the injector. If after checking, this noise comes from another component of the engine of your Mazda 5, read this content page for more infos.
The effects of injector noise on Mazda 5
Now that we have examined the different causes for injector noise on your Mazda 5, we will end by stating the possible side effects 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 side effects which can almost instantly become serious….
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 common effects experienced by drivers is a significant loss of power. In fact, if your engine is running on 3 out of 4 cylinders for example, you will obviously have a loss of power
Finally, you risk degrading 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 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>
