It is hardly ever pleasant to listen to an injector noise on your Tesla Model S. It is a noise that comes up regularly, usually when you accelerate or your engine is idling. However, this indication may be related to multiple types of problems with your car injectors. It may not be anything severe, but when a repeated noise arises, you have to be sure. Specifically since replacing your Tesla Model S’s injectors can be expensive. That’s why our team chose to produce this article in order to support you see more clearly, learn about the different conceivable failures and distinguish your issue. To do this, we will first look at the normal running and usefulness of the injectors in your Tesla Model S, then at the conceivable triggers from which an injector noise may come.
Purposes of the injectors
Injectors are a very fundamental component of the operation of your engine unit. They were launched to the modern cars about 20 years ago. Before their introduction, 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 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 accumulated from the various sensors equipping the car (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 obtain the best possible combustion in the cylinders.
The different reasons of a clicking or knocking noise coming from the injectors of your Tesla Model S
Finding out injector noises on your Tesla Model S may result from different sources, 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 different origins of these noises and the solutions to be adopted to eliminate them. If you listen to another clicking noise but it is not from your injectors, we recommend you to browse this article about clicking noise on Tesla Model S to discover the reason.
The causes for injector clicking or knocking noise Tesla Model S
A clicking or knocking noise from your injectors can be explained for different causes. Indeed, the injectors of your Tesla Model S have three main tasks, to control the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to facilitate its combustion. Then, its objective is to manage the air/fuel dosage and at last the homogeneity of the mixture, always with the target of improving combustion. If one of these three features is modified, the main functionality of the injectors will be disturbed 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 trigger thoses knocking or clicking noises on your Tesla Model S. The main reason of these trouble in most cases originates from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible blockage will inevitably cause a malfunction of the injector. If after checking, this noise originates from another component of the engine of your Tesla Model S, check this article for more informations.
The repercussions of injector noise on Tesla Model S
Now that we have examined the diverse causes for injector noise on your Tesla Model S, we will end by stating the possible effects of malfunctioning one or more of your injectors. Whether only one is clogged, or damaged, or your entire fuel rail is involved, you cannot escape these side effects which can almost instantly become critical….
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 felt by drivers is a distinctive 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 deteriorating one of your pistons or your engine. Poor combustion will almost instantly affect 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>
