Iemand dit al gezien?

It's been a long time since the automotive world has bothered with the mixing of oil and gas of the two-stroke combustion cycle — but soon, it may come time to rid ourselves of four-stroke engines, if a set of patent filings from Porsche for a six-stroke engine are a hint of what's to come.

As patent filings with the U.S. Patent and Trademark Office recently highlighted by Motor1 reveal, Porsche has come up with a detailed plan for a newly developed six-stroke design. Instead of relying on a traditional combination of intake, compression, power, and exhaust, Porsche wants to try adding on an extra compression and power stroke, according to the documents.

Vanuit technologisch perspectief en wellicht in combinatie met synthetische brandstof erg interessant!
Echter is het de vraag of dit soort kapitaalintensieve innovaties op dit moment een hoge prioriteit zal krijgen binnen het geplaagde VAG concern.
Porsche doet er in ieder geval alles aan om de brandstofmotor voor de 911 te behouden.
