It is hardly ever enjoyable to perceive an injector noise on your Tesla Model 3. It is a noise that appears continually, usually when you accelerate or your engine is idling. However, this symptom may be connected to different kind of concerns with your car injectors. It may not be anything serious, but when a persistent noise appears, you have to be sure. Especially since repairing your Tesla Model 3’s injectors can be expensive. That’s why our team decided to compose this article in order to support you see more clearly, learn about the different possible failures and identify your trouble. To do this, we will first look at the normal function and usefulness of the injectors in your Tesla Model 3, then at the possible reasons from which an injector noise may come.injector-noise-tesla-model-3

Attributes of the injectors

Injectors are a very vital element of the operation of your engine motor. They were introduced to the modern vehicles about 20 years ago. Before their introduction, 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 ability, 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 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 get the best possible combustion in the cylinders.

The different reasons of a clicking or knocking noise caused by the injectors of your Tesla Model 3

Hearing injector noises on your Tesla Model 3 may come from different locations, we will now center on the potential causes of these. Generally, the typical noise of a faulty injector is of the snap type. Here are the different origins of these noises and the solutions to be applied to prevent them. If you perceive another clicking noise but it is not from your injectors, we advise you to read this article about clicking noise on Tesla Model 3 to discover the reason.

The reasons for injector clicking or knocking noise Tesla Model 3

A clicking or knocking noise from your injectors can be justified by different reasons. Indeed, the injectors of your Tesla Model 3 have three main tasks, 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 deal with the air/fuel dosage and at last the homogeneity of the mixture, always with the objective of improving combustion. If one of these three attributes is altered, the main purpose of the injectors will be disturbed 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 provoke thoses knocking or clicking noises on your Tesla Model 3. The main reason of these situations generally originates from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible blockage will inevitably produce a malfunction of the injector. If after checking, this noise originates from another element of the engine of your Tesla Model 3, check this article for more informations.

The repercussions of injector noise on Tesla Model 3

Now that we have analyzed the diverse causes for injector noise on your Tesla Model 3, we will end by stating the possible end result of malfunctioning one or more of your injectors. Whether only one is blocked, or broken, or your entire fuel rail is involved, you cannot escape these side effects which can promptly become serious….
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 regular consequences felt by drivers is a serious loss of power. Indeed, if your engine is running on 3 out of 4 cylinders for example, you will obviously 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 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>
