Basically, this thing is a mashup of four-stroke and a two-stroke engine designs (here's how an engine works, by the way), that results in two power strokes in three revolutions.

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 is working very hard at finding ways to keep combustion engines alive amid the push for electric power

The AutoGuide research department strikes again— this time discovering a wild new engine concept from Porsche that could bring huge gains in both efficiency and power density.Porsche has filed a paten

The patented engine design features a special crankshaft that adds more power and compression strokes to the cycle.
