Will petrol/diesel cars survive? Porsche's six-stroke engine could be the answer: Details German luxury carmaker Porsche appears to be on course to find a solution for the ‘dying’ internal combustion engines . The company has filed a patent for a six-stroke engine . This innovation could breathe new life into combustion engines , even as the automotive world increasingly leans toward hybrid and electric powertrains .
Six-stroke engines: What’s different The traditional four-stroke engine, which has been the backbone of ICE vehicles for decades, operates on a cycle of intake, compression, power, and exhaust. However, Porsche's newly designed six-stroke engine adds two more phases—an additional compression and power stroke—allowing for more frequent energy generation. As a result, the process returns more efficiency and performance - and eventually lesser emissions.

Well, this six-stroke design has a unique crankshaft that enables increased compression without expanding the engine’s size. The additional compression and power strokes not only boost engine power but also ensure a more thorough combustion of the fuel, minimizing waste and optimizing the air-fuel mixture. According to Porsche’s patent application, the sequence for the six-stroke engine works in two sets of three strokes: intake-compression-power, followed by compression-power-exhaust.
