Attributes of the injectors

Injectors are a very fundamental part of the operation of your engine. They were brought in to the modern vehicles 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 opportunity, 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 vehicle (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 get the best possible combustion in the cylinders.

The different reasons of a clicking or knocking noise coming from the injectors of your Chevrolet Tahoe

Experiencing injector noises on your Chevrolet Tahoe may originate from different origins, we will now focus on the potential causes of these. In most cases, the regular noise of a faulty injector is of the snap type. Here are the several sources of these noises and the solutions to be used to prevent them.

The reasons for injector clicking or knocking noise Chevrolet Tahoe

A clicking or knocking noise from your injectors can be justified by different reasons. In fact, the injectors of your Chevrolet Tahoe have three main tasks, to manage the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to facilitate its combustion. Then, its task is to manage the air/fuel dosage and finally the homogeneity of the mixture, always with the goal of improving combustion. If one of these three functions is modified, the main purpose 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 provoke thoses knocking or clicking noises on your Chevrolet Tahoe. The main cause of these concerns 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 end up in a malfunction of the injector.

The repercussions of injector noise on Chevrolet Tahoe

Now that we have reviewed the different causes for injector noise on your Chevrolet Tahoe, we will end by stating the possible side effects of malfunctioning one or more of your injectors. Whether only one is obstructed, or broken, or your entire fuel rail is involved, you cannot escape these effects which can promptly become considerable….
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 common consequences felt by drivers is a serious loss of power. In fact, if your engine is running on 3 out of 4 cylinders for example, you will undoubtedly have a loss of power
Finally, you risk deteriorating 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 recommendations 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 swapping your diesel fuel filter regularly>
