It is rarely ever relaxing to notice an injector noise on your Chevrolet Cruze. It is a noise that comes up frequently, usually when you accelerate or your engine is idling. However, this symptom may be relating to different kind of problems with your automobile injectors. It may not be anything severe, but when a persistent noise appears, you have to be sure. Especially since fixing your Chevrolet Cruze’s injectors can be costly. That’s why our team chose to produce this article in order to help you see more clearly, learn about the different plausible failures and distinguish your trouble. To do this, we will first look at the normal function and usefulness of the injectors in your Chevrolet Cruze, then at the plausible triggers from which an injector noise may come.injector-noise-chevrolet-cruze

Functions of the injectors

Injectors are a very important component of the operation of your engine unit. They were introduced to the modern vehicles 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 compiled from the various sensors equipping the automobile (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 Cruze

Listening injector noises on your Chevrolet Cruze may result from different locations, we will now look into the potential triggers of these. Generally, the typical noise of a faulty injector is of the snap type. Here are the several origins of these noises and the solutions to be implemented to get rid of them. If you notice another clicking noise but it is not from your injectors, we recommend you to examine this article about clicking noise on Chevrolet Cruze to locate the reason.

The reasons for injector clicking or knocking noise Chevrolet Cruze

A clicking or knocking noise from your injectors can be explained for different reasons. Indeed, the injectors of your Chevrolet Cruze 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 deal with the air/fuel dosage and at last the homogeneity of the mixture, always with the target of improving combustion. If one of these three attributes 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 Cruze. The main reason of these trouble in most cases originates from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible blockage will inevitably result in a malfunction of the injector.

The consequences of injector noise on Chevrolet Cruze

Now that we have examined the diverse causes for injector noise on your Chevrolet Cruze, 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 side effects which can promptly become major….
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 effects experienced by drivers is a noticeable loss of power. Indeed, if your engine is running on 3 out of 4 cylinders for example, you will undoubtedly have a loss of power
Finally, you risk degrading 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 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>
