Porsche is working on an innovative engine concept that could bring significant gains in efficiency and power density.
First discovered by our sister site, AutoGuide, Porsche has filed a patent application (Appl. No. 18/585,308) with the United States Patent and Trademark Office (USPTO), developed in collaboration with the Technical University of Cluj-Napoca in Romania. This patent outlines a unique "two times three strokes" engine design that could potentially revolutionize internal combustion technology.
The engine uses a crankshaft mechanism that moves within a ring (annulus) to create a motion similar to a spirograph toy. This unique design allows the crankshaft to rotate with two different top dead centers (TDC) and two different bottom dead centers (BDC) during the cycle.
