It is rarely ever enjoyable to listen to an injector noise on your Chevrolet Avalanche. It is a noise that happens frequently, usually when you accelerate or your engine is idling. However, this warning sign may be linked to multiple sort of problems with your car injectors. It may not be anything major, but when a recurrent noise happens, you have to be sure. Specifically since repairing your Chevrolet Avalanche’s injectors can be costly. That’s why our team chose to produce this article in order to support you see more clearly, learn about the different possible failures and identify your trouble. To do this, we will first look at the normal running and usefulness of the injectors in your Chevrolet Avalanche, then at the possible causes from which an injector noise may come.
Functions of the injectors
Injectors are a very useful component of the operation of your engine unit. They were released to the modern vehicles 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 received from the various sensors equipping the car (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 obtain the best possible combustion in the cylinders.
The different triggers of a clicking or knocking noise based on the injectors of your Chevrolet Avalanche
Hearing injector noises on your Chevrolet Avalanche may originate from different sources, we will now look into the potential triggers of these. Generally, the regular noise of a faulty injector is of the snap type. Here are the different origins of these noises and the solutions to be adopted to stop them. If you listen to another clicking noise but it is not from your injectors, we recommend you to read this article about clicking noise on Chevrolet Avalanche to find the reason.
The reasons for injector clicking or knocking noise Chevrolet Avalanche
A clicking or knocking noise from your injectors can be justified by different reasons. In fact, the injectors of your Chevrolet Avalanche have three main tasks, to manage the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to ease its combustion. Then, its task is to control the air/fuel dosage and at last the homogeneity of the mixture, always with the aim of improving combustion. If one of these three attributes is altered, 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 resulting from bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will trigger thoses knocking or clicking noises on your Chevrolet Avalanche. The main reason of these concerns commonly originates from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible blockage will inevitably produce a malfunction of the injector. If after verifying, this noise originates from another component of the engine of your Chevrolet Avalanche, check this article for more informations.
The side effects of injector noise on Chevrolet Avalanche
Now that we have examined the diverse causes for injector noise on your Chevrolet Avalanche, we will end by stating the possible end result 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 almost instantly become considerable….
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 repercussions noticed 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 almost instantly affect 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 changing your diesel fuel filter regularly>
