It is hardly ever pleasant to listen an injector noise on your Chevrolet Silverado. It is a noise that arises continually, usually when you accelerate or your engine is idling. However, this warning sign may be connected to several sort of trouble with your car injectors. It may not be anything severe, but when a persistent noise shows up, you have to be sure. Most importantly since repairing your Chevrolet Silverado’s injectors can be expensive. That’s why our team chose to write this content in order to help 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 Silverado, then at the possible reasons from which an injector noise may come.injector-noise-chevrolet-silverado

Functions of the injectors

Injectors are a very important part of the operation of your engine. They were launched to the modern cars 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 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 collected from the various sensors equipping the car (engine temperature, acceleration level, engine speed, etc.). Their objective 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 coming from the injectors of your Chevrolet Silverado

Hearing injector noises on your Chevrolet Silverado may result from different sources, we will now look into the potential triggers of these. In general, the common noise of a faulty injector is of the snap type. Here are the several sources of these noises and the solutions to be applied to get rid of them. If you listen another clicking noise but it is not from your injectors, we suggest you to read this content about clicking noise on Chevrolet Silverado to find the cause.

The causes for injector clicking or knocking noise Chevrolet Silverado

A clicking or knocking noise from your injectors can be justified by different causes. In fact, the injectors of your Chevrolet Silverado have three main tasks, to control the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to facilitate its combustion. Then, its goal is to deal with 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 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 provoke thoses knocking or clicking noises on your Chevrolet Silverado. The main cause of these situations in most cases comes from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible blockage will inevitably cause a malfunction of the injector.

The side effects of injector noise on Chevrolet Silverado

Now that we have examined the diverse reasons for injector noise on your Chevrolet Silverado, we will end by stating the possible end result of malfunctioning one or more of your injectors. Whether only one is obstructed, or damaged, or your entire fuel rail is involved, you cannot escape these consequences which can promptly become severe….
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 regular effects felt by drivers is a noticeable 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 promptly harm 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>
