It is never pleasant to notice an injector noise on your Cadillac ATS. It is a noise that comes up continually, usually when you accelerate or your engine is idling. However, this warning sign may be connected to different kind of trouble with your car injectors. It may not be anything major, but when a repeated noise happens, you have to be sure. Most importantly since replacing your Cadillac ATS’s injectors can be costly. That’s why our team chose to compose this article in order to support you see more clearly, learn about the different plausible failures and determine your trouble. To do this, we will first look at the normal functioning and usefulness of the injectors in your Cadillac ATS, then at the plausible reasons from which an injector noise may come.
Attributes of the injectors
Injectors are a very useful element of the operation of your engine unit. They were brought in to the modern cars about 20 years ago. Before their appearance, 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 compiled from the various sensors equipping the car (engine temperature, acceleration level, engine speed, etc.). Their goal is therefore to inject under high pressure a precise quantity of an air/fuel mixture at a perfect timing to obtain the best possible combustion in the cylinders.
The different causes of a clicking or knocking noise caused by the injectors of your Cadillac ATS
Listening injector noises on your Cadillac ATS may result from different origins, we will now focus on the potential triggers of these. In most cases, the regular noise of a faulty injector is of the snap type. Here are the several origins of these noises and the solutions to be adopted to get rid of them. If you notice another clicking noise but it is not from your injectors, we recommend you to go through this article about clicking noise on Cadillac ATS to discover the reason.
The explanations for injector clicking or knocking noise Cadillac ATS
A clicking or knocking noise from your injectors can be explained for different explanations. In fact, the injectors of your Cadillac ATS have three main missions, to manage the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to facilitate its combustion. Then, its mission is to deal with the air/fuel dosage and finally the homogeneity of the mixture, always with the target of improving combustion. If one of these three characteristics is altered, the main purpose 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 Cadillac ATS. The main reason of these situations in most cases comes from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible obstruction will inevitably produce a malfunction of the injector. If after checking, this noise comes from another element of the engine of your Cadillac ATS, read this article for more informations.
The consequences of injector noise on Cadillac ATS
Now that we have analyzed the different causes for injector noise on your Cadillac ATS, we will end by stating the possible side effects 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 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 repercussions noticed 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 surely have a loss of power
Finally, you risk deteriorating 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 tips to limit the risks connected 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>
