It is never enjoyable to listen an injector noise on your PORSCHE BOXSTER. It is a noise that appears regularly, usually when you accelerate or your engine is idling. However, this indicator may be relating to different sort of problems with your automobile injectors. It may not be anything major, but when a continuing noise arises, you have to be sure. Especially since fixing your PORSCHE BOXSTER’s injectors can be expensive. That’s why our team chose to create this article in order to support you see more clearly, learn about the different possible failures and identify your issue. To do this, we will first look at the normal function and usefulness of the injectors in your PORSCHE BOXSTER, then at the possible triggers from which an injector noise may come.
Purposes of the injectors
Injectors are a very vital part of the operation of your engine. 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 automobile (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 causes of a clicking or knocking noise based on the injectors of your PORSCHE BOXSTER
Hearing injector noises on your PORSCHE BOXSTER may come from different sources, we will now center on the potential causes of these. Generally, the common noise of a faulty injector is of the snap type. Here are the different sources of these noises and the solutions to be adopted to prevent them. If you listen another clicking noise but it is not from your injectors, we advise you to read this article about clicking noise on PORSCHE BOXSTER to discover the reason.
The reasons for injector clicking or knocking noise PORSCHE BOXSTER
A clicking or knocking noise from your injectors can be justified by different reasons. Indeed, the injectors of your PORSCHE BOXSTER have three main tasks, to manage the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to ease its combustion. Then, its objective is to deal with the air/fuel dosage and finally the homogeneity of the mixture, always with the goal of improving combustion. If one of these three features is modified, the main role 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 PORSCHE BOXSTER. The main reason of these trouble commonly comes 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.

The end result of injector noise on PORSCHE BOXSTER
Now that we have reviewed the diverse reasons for injector noise on your PORSCHE BOXSTER, 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 effects which can almost instantly 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 experienced 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 almost instantly damage your cylinders or pistons and your engine may tighten.
Here are three little recommendations to limit the risks relating 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>
