It is rarely ever enjoyable to hear an injector noise on your Chevrolet Corvette. It is a noise that arises frequently, usually when you accelerate or your engine is idling. However, this symptom may be related to several types of problems with your car injectors. It may not be anything major, but when a frequent noise comes out, you have to be sure. Especially since replacing your Chevrolet Corvette’s injectors can be expensive. That’s why our team decided to prepare this article in order to help you see more clearly, learn about the different plausible failures and distinguish your problem. To do this, we will first look at the normal functioning and usefulness of the injectors in your Chevrolet Corvette, then at the plausible reasons from which an injector noise may come.injector-noise-chevrolet-corvette

Functions of the injectors

Injectors are a very important element of the operation of your engine. They were released to the modern cars about 20 years ago. Before their arrival, 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 accurately (quantity of fuel injected, air/fuel mixture) via the analysis of the data accumulated 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 get the best possible combustion in the cylinders.

The different origins of a clicking or knocking noise caused by the injectors of your Chevrolet Corvette

Discovering injector noises on your Chevrolet Corvette may result from different origins, we will now focus on the potential causes of these. Generally, the common noise of a faulty injector is of the snap type. Here are the different origins of these noises and the solutions to be applied to prevent them. If you hear another clicking noise but it is not from your injectors, we encourage you to go through this article about clicking noise on Chevrolet Corvette to locate the trigger.

The causes for injector clicking or knocking noise Chevrolet Corvette

A clicking or knocking noise from your injectors can be explained for different causes. In fact, the injectors of your Chevrolet Corvette have three main missions, to control the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to facilitate its combustion. Then, its mission 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 features is altered, the main role of the injectors will be disrupted and this will lead to poor combustion. This bad combustion will be a violent explosion in the cylinders due to bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will induce thoses knocking or clicking noises on your Chevrolet Corvette. The main trigger of these concerns 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 in a malfunction of the injector.

The repercussions of injector noise on Chevrolet Corvette

Now that we have reviewed the different causes for injector noise on your Chevrolet Corvette, we will end by stating the possible end result of malfunctioning one or more of your injectors. Whether only one is clogged, or broken, or your entire fuel rail is involved, you cannot escape these repercussions which can almost instantly 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 significant 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 damage your cylinders or pistons and your engine may tighten.
Here are three little recommendations to limit the risks linked 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>
