It is never pleasurable to hear an injector noise on your Chevrolet Trax. It is a noise that happens continually, usually when you accelerate or your engine is idling. However, this sign may be related to several sort of problems with your vehicle injectors. It may not be anything serious, but when a frequent noise appears, you have to be sure. Most importantly since replacing your Chevrolet Trax’s injectors can be expensive. That’s why our team chose to create this content page in order to support you see more clearly, learn about the different conceivable failures and distinguish your trouble. To do this, we will first look at the normal running and usefulness of the injectors in your Chevrolet Trax, then at the conceivable triggers from which an injector noise may come.
Functions of the injectors
Injectors are a very fundamental part of the operation of your engine. 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 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 obtained 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 origins of a clicking or knocking noise caused by the injectors of your Chevrolet Trax
Discovering injector noises on your Chevrolet Trax may result from different locations, we will now look into the potential causes of these. Generally, the usual noise of a faulty injector is of the snap type. Here are the several sources of these noises and the solutions to be adopted to eliminate them. If you hear another clicking noise but it is not from your injectors, we advise you to read this content page about clicking noise on Chevrolet Trax to discover the trigger.
The causes for injector clicking or knocking noise Chevrolet Trax
A clicking or knocking noise from your injectors can be explained for different causes. In fact, the injectors of your Chevrolet Trax have three main missions, to control the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to ease its combustion. Then, its objective is to manage the air/fuel dosage and at last the homogeneity of the mixture, always with the aim of improving combustion. If one of these three tasks 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 resulting from bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will induce thoses knocking or clicking noises on your Chevrolet Trax. The main trigger of these situations commonly originates from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible obstruction will inevitably produce a malfunction of the injector. If after checking, this noise originates from another component of the engine of your Chevrolet Trax, check this content page for more infos.
The side effects of injector noise on Chevrolet Trax
Now that we have reviewed the diverse causes for injector noise on your Chevrolet Trax, 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 effects which can promptly become considerable….
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 known 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 inevitably have a loss of power
Finally, you risk deteriorating one of your pistons or your engine. Poor combustion will promptly 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>
