Porsche’s 6-stroke engine innovation could rewrite automotive engineering

Porsche has filed a patent for a revolutionary six-stroke engine design, potentially marking a major shift in automotive engineering. The key innovation is a crankshaft rotating around two concentric circles, reducing piston travel and improving efficiency. This design produces power every third stroke instead of every fourth, aiming to maximize power output and fuel efficiency. While six-stroke engines aren't new, Porsche's approach is more advanced, offering potential advantages like increased thermal efficiency (45-50% compared to 30% for typical four-stroke engines) and reduced emissions.
