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.
