It is never relaxing to perceive an injector noise on your Porsche 911. It is a noise that comes up frequently, usually when you accelerate or your engine is idling. However, this indication may be relating to multiple types of trouble with your car injectors. It may not be anything severe, but when a repeated noise comes out, you have to be sure. Specifically since fixing your Porsche 911’s injectors can be costly. That’s why our team chose to produce this content page in order to support you see more clearly, learn about the different plausible failures and distinguish your problem. To do this, we will first look at the normal function and usefulness of the injectors in your Porsche 911, then at the plausible causes from which an injector noise may come.
Attributes of the injectors
Injectors are a very fundamental component of the operation of your engine unit. They were brought in 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 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 collected 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 triggers of a clicking or knocking noise caused by the injectors of your Porsche 911
Discovering injector noises on your Porsche 911 may come from different origins, we will now focus on the potential causes of these. In most cases, 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 eliminate them. If you perceive another clicking noise but it is not from your injectors, we suggest you to browse this content page about clicking noise on Porsche 911 to discover the cause.
The reasons for injector clicking or knocking noise Porsche 911
A clicking or knocking noise from your injectors can be justified by different reasons. Indeed, the injectors of your Porsche 911 have three main missions, to control the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to facilitate its combustion. Then, its goal is to control the air/fuel dosage and finally the homogeneity of the mixture, always with the goal of improving combustion. If one of these three characteristics is modified, 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 because of bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will provoke thoses knocking or clicking noises on your Porsche 911. The main cause of these problems 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 lead to a malfunction of the injector. If after checking, this noise comes from another part of the engine of your Porsche 911, check this content page for more informations.
The effects of injector noise on Porsche 911
Now that we have examined the diverse causes for injector noise on your Porsche 911, we will end by stating the possible consequences 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 repercussions which can fairly quickly become considerable….
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 repercussions noticed by drivers is a significant loss of power. Indeed, if your engine is running on 3 out of 4 cylinders for example, you will inevitably 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 linked 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>
