It is rarely ever pleasurable to acknowledge an injector noise on your Chevrolet Bolt. It is a noise that happens continually, usually when you accelerate or your engine is idling. However, this symptom may be related to different sort of problems with your vehicle injectors. It may not be anything major, but when a repeated noise happens, you have to be sure. Most importantly since repairing your Chevrolet Bolt’s injectors can be expensive. That’s why our team chose to write this article in order to support you see more clearly, learn about the different plausible failures and determine your problem. To do this, we will first look at the normal functioning and usefulness of the injectors in your Chevrolet Bolt, then at the plausible reasons from which an injector noise may come.
Functions of the injectors
Injectors are a very vital component of the operation of your engine unit. They were launched to the modern automobiles 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 accurately (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 coming from the injectors of your Chevrolet Bolt
Experiencing injector noises on your Chevrolet Bolt may originate from different locations, we will now center on the potential triggers of these. In general, the usual noise of a faulty injector is of the snap type. Here are the several origins of these noises and the solutions to be put into practice to get rid of them. If you acknowledge another clicking noise but it is not from your injectors, we suggest you to examine this article about clicking noise on Chevrolet Bolt to discover the cause.
The causes for injector clicking or knocking noise Chevrolet Bolt
A clicking or knocking noise from your injectors can be justified by different causes. Indeed, the injectors of your Chevrolet Bolt have three main missions, to control the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to ease its combustion. Then, its task is to manage the air/fuel dosage and finally the homogeneity of the mixture, always with the objective of improving combustion. If one of these three characteristics 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 induce thoses knocking or clicking noises on your Chevrolet Bolt. The main cause of these problems commonly 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. If after verifying, this noise originates from another element of the engine of your Chevrolet Bolt, have a look at this article for more infos.
The repercussions of injector noise on Chevrolet Bolt
Now that we have reviewed the several causes for injector noise on your Chevrolet Bolt, 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 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 regular effects noticed by drivers is a serious 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 fairly quickly harm your cylinders or pistons and your engine may tighten.
Here are three little suggestions to limit the risks connected 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>
