It is rarely ever pleasant to notice an injector noise on your Chevrolet Equinox. It is a noise that comes up frequently, usually when you accelerate or your engine is idling. However, this symptom may be relating to different sort of trouble with your vehicle injectors. It may not be anything serious, but when a frequent noise happens, you have to be sure. Especially since fixing your Chevrolet Equinox’s injectors can be costly. That’s why our team chose to compose this content page in order to support you see more clearly, learn about the different possible failures and establish your issue. To do this, we will first look at the normal running and usefulness of the injectors in your Chevrolet Equinox, then at the possible reasons from which an injector noise may come.
Functions of the injectors
Injectors are a very useful element of the operation of your engine motor. They were brought in to the modern automobiles 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 compiled 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 origins of a clicking or knocking noise coming from the injectors of your Chevrolet Equinox
Discovering injector noises on your Chevrolet Equinox may originate from different origins, we will now concentrate on the potential triggers of these. In general, the usual noise of a faulty injector is of the snap type. Here are the several sources of these noises and the solutions to be adopted to get rid of them. If you notice another clicking noise but it is not from your injectors, we advise you to go through this content page about clicking noise on Chevrolet Equinox to locate the trigger.
The causes for injector clicking or knocking noise Chevrolet Equinox
A clicking or knocking noise from your injectors can be explained for different causes. Indeed, the injectors of your Chevrolet Equinox have three main tasks, to manage the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to facilitate its combustion. Then, its goal is to control the air/fuel dosage and finally the homogeneity of the mixture, always with the target of improving combustion. If one of these three features 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 because of bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will trigger thoses knocking or clicking noises on your Chevrolet Equinox. The main trigger of these problems commonly originates from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible obstruction will inevitably lead to a malfunction of the injector.

The repercussions of injector noise on Chevrolet Equinox
Now that we have analyzed the several reasons for injector noise on your Chevrolet Equinox, we will end by stating the possible effects 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 side effects which can fairly quickly become major….
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 known repercussions noticed by drivers is a significant loss of power. Indeed, if your engine is running on 3 out of 4 cylinders for example, you will obviously have a loss of power
Finally, you risk deteriorating 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 associated 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>
