Porsche Patents 6-Stroke Engine
Porsche Has Dreamed Up a 6-Stroke Combustion Engine, Patent Documents Show
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.
Porsche's 6-stroke engine doubles up on power and compression
Intake, compression, power, then exhaust. Every 4-stroke engine ever made – about 80% of all engines currently in existence – function on this principle – even rotary engines. But now, Porsche has filed a patent to make a 6-stroke engine.
