It is hardly ever enjoyable to experience an injector noise on your PORSCHE 718. It is a noise that arises regularly, usually when you accelerate or your engine is idling. However, this indication may be related to several kind of complications with your vehicle injectors. It may not be anything serious, but when a frequent noise happens, you have to be sure. Specifically since replacing your PORSCHE 718’s injectors can be costly. That’s why our team chose to produce this article in order to help you see more clearly, learn about the different plausible failures and determine your problem. To do this, we will first look at the normal function and usefulness of the injectors in your PORSCHE 718, then at the plausible reasons from which an injector noise may come.injector-noise-porsche-718

Functions of the injectors

Injectors are a very vital part of the operation of your engine. 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 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 compiled from the various sensors equipping the vehicle (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 get the best possible combustion in the cylinders.

The different triggers of a clicking or knocking noise based on the injectors of your PORSCHE 718

Finding out injector noises on your PORSCHE 718 may come from different origins, we will now focus on the potential triggers of these. Generally, the regular noise of a faulty injector is of the snap type. Here are the different origins of these noises and the solutions to be implemented to stop them. If you experience another clicking noise but it is not from your injectors, we recommend you to read this article about clicking noise on PORSCHE 718 to discover the trigger.

The explanations for injector clicking or knocking noise PORSCHE 718

A clicking or knocking noise from your injectors can be justified by different explanations. In fact, the injectors of your PORSCHE 718 have three main tasks, to manage the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to facilitate its combustion. Then, its task is to control the air/fuel dosage and at last the homogeneity of the mixture, always with the target of improving combustion. If one of these three characteristics is modified, 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 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 PORSCHE 718. The main trigger of these situations generally comes from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible blockage will inevitably end in a malfunction of the injector. If after verifying, this noise comes from another element of the engine of your PORSCHE 718, check this article for more informations.

The effects of injector noise on PORSCHE 718

Now that we have reviewed the several causes for injector noise on your PORSCHE 718, we will end by stating the possible effects of malfunctioning one or more of your injectors. Whether only one is obstructed, or damaged, or your entire fuel rail is involved, you cannot escape these effects which can promptly become serious….
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 felt 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 obviously have a loss of power
Finally, you risk deteriorating 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 tips 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>
