Porsche's 6-Stroke Engine Is Fascinating – More Power!
By Engineering Explained
Porsche patented a 6-stroke engine, yes, two more strokes than you’d commonly see for a combustion engine, and most excitingly, one of those additional strokes is a power-stroke! We now have two power strokes per cylinder within the full six-stroke cycle. The way it works is through Porsche’s genius hypocycloidal design which the crankshaft follows. This creates two different stopping heights for the piston at both the top, and the bottom of the cylinder. The first three strokes you’ve seen before, intake, compression, power, but at the end of our third stroke, the first power stroke, the pis…
