It is never pleasant to experience an injector noise on your Mazda CX 5. It is a noise that happens continually, usually when you accelerate or your engine is idling. However, this indicator may be connected to several kind of concerns with your automobile injectors. It may not be anything severe, but when a repeated noise appears, you have to be sure. Specifically since replacing your Mazda CX 5’s injectors can be costly. That’s why our team decided to produce this content page in order to support you see more clearly, learn about the different plausible failures and establish your issue. To do this, we will first look at the normal function and usefulness of the injectors in your Mazda CX 5, then at the plausible triggers from which an injector noise may come.
Benefits of the injectors
Injectors are a very useful part of the operation of your engine motor. They were launched to the modern automobiles about 20 years ago. Before their appearance, 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 precisely (quantity of fuel injected, air/fuel mixture) via the analysis of the data collected from the various sensors equipping the automobile (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 triggers of a clicking or knocking noise caused by the injectors of your Mazda CX 5
Experiencing injector noises on your Mazda CX 5 may come from different origins, we will now center on the potential triggers of these. Generally, the common noise of a faulty injector is of the snap type. Here are the different sources of these noises and the solutions to be used to prevent them. If you experience another clicking noise but it is not from your injectors, we encourage you to read this content page about clicking noise on Mazda CX 5 to discover the cause.
The reasons for injector clicking or knocking noise Mazda CX 5
A clicking or knocking noise from your injectors can be explained for different reasons. In fact, the injectors of your Mazda CX 5 have three main missions, to control the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to facilitate its combustion. Then, its task is to deal with the air/fuel dosage and at last the homogeneity of the mixture, always with the objective of improving combustion. If one of these three tasks is modified, the main functionality 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 CX 5. The main cause of these situations generally originates from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible obstruction 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 5, check this content page for more infos.
The consequences of injector noise on Mazda CX 5
Now that we have analyzed the diverse reasons for injector noise on your Mazda CX 5, we will end by stating the possible side effects of malfunctioning one or more of your injectors. Whether only one is blocked, or damaged, or your entire fuel rail is involved, you cannot escape these effects which can fairly quickly 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 basic effects felt 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 fairly quickly affect your cylinders or pistons and your engine may tighten.
Here are three little suggestions 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>
