Anyone remember the new engine design where the pistons go around in a circle type track? The pistons travel 360 degrees connected to a central crank instead of up and down within the cylinder wall. Along the way, it would pickup the intake, air/fuel, combust, and flush the exhaust.

Are you talking about the Wankel engine? It was originally made back in the 1950s.

No, no. This thing used what looked almost like normal pistons, but they traveled in a closed 360 degree circular track which was the combustion chamber. Somewhat like the Wankel, it functioned thru the engine cycles as it went around the track.
