Attributes of the injectors

Injectors are a very vital part of the operation of your engine motor. 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 accurately (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 get the best possible combustion in the cylinders.

The different reasons of a clicking or knocking noise based on the injectors of your Buick Encore

Discovering injector noises on your Buick Encore may come from different locations, we will now focus on the potential triggers of these. In most cases, the usual 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 eliminate them. If you hear another clicking noise but it is not from your injectors, we advise you to browse this article about clicking noise on Buick Encore to locate the trigger.

The reasons for injector clicking or knocking noise Buick Encore

A clicking or knocking noise from your injectors can be justified by different reasons. In fact, the injectors of your Buick Encore 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 objective is to control 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 disturbed 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 Buick Encore. The main trigger of these situations usually comes from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible blockage will inevitably cause a malfunction of the injector.

The consequences of injector noise on Buick Encore

Now that we have examined the diverse causes for injector noise on your Buick Encore, we will end by stating the possible side 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 repercussions 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 consequences 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 surely 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 connected 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>
