It is never pleasant to listen to an injector noise on your Chevrolet Suburban. It is a noise that happens regularly, usually when you accelerate or your engine is idling. However, this indication may be linked to several sort of complications with your vehicle injectors. It may not be anything serious, but when a repeated noise comes out, you have to be sure. Most importantly since fixing your Chevrolet Suburban’s injectors can be expensive. That’s why our team chose to create this article content in order to support you see more clearly, learn about the different conceivable failures and determine your issue. To do this, we will first look at the normal functioning and usefulness of the injectors in your Chevrolet Suburban, then at the conceivable causes from which an injector noise may come.
Benefits of the injectors
Injectors are a very useful element of the operation of your engine. They were introduced to the modern vehicles about 20 years ago. Before their arrival, more conventional carburettor-type intake systems were employed, 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 precisely (quantity of fuel injected, air/fuel mixture) via the analysis of the data received 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 triggers of a clicking or knocking noise caused by the injectors of your Chevrolet Suburban
Hearing injector noises on your Chevrolet Suburban may result from different locations, we will now concentrate on the potential causes of these. Generally, 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 implemented to stop them. If you listen to another clicking noise but it is not from your injectors, we advise you to read this article content about clicking noise on Chevrolet Suburban to locate the cause.
The reasons for injector clicking or knocking noise Chevrolet Suburban
A clicking or knocking noise from your injectors can be justified by different reasons. In fact, the injectors of your Chevrolet Suburban have three main tasks, to control the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to ease its combustion. Then, its objective is to deal with the air/fuel dosage and at last the homogeneity of the mixture, always with the objective of improving combustion. If one of these three features is altered, 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 trigger thoses knocking or clicking noises on your Chevrolet Suburban. The main cause of these problems commonly comes from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible blockage will inevitably end up in a malfunction of the injector. If after checking, this noise comes from another element of the engine of your Chevrolet Suburban, read this article content for more informations.
The consequences of injector noise on Chevrolet Suburban
Now that we have reviewed the several reasons for injector noise on your Chevrolet Suburban, we will end by stating the possible end result 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 repercussions which can fairly quickly become severe….
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 regular effects experienced 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 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 recommendations 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>
