This is actually pretty clever, though I wonder how you'd cool the rotor so that the seals still work seeing how you have fresh air coming in right next to the exhaust, so the rotor would be expanding on one half only. Maybe Or maybe they just do the whole spring loaded thing again like on the Wankel engines. Also it probably loses a shitload of efficiency at low speed since it essentially has the piston equivalent of 180 degrees dwell at TDC, unless of course you're doing a compression ignition setup. Would be great for a motorcycle engine though, I'll have to get this custom machined someday if I get rich. |
Ow, my brain...
Parts that look horribly inefficient to me are the flow through the ports (two sharp 90° turns? No thanks...) and how combustion pressure seems to also push partly against the direction of of the rotor
My conclusion, (based on not being an engineer, briefly viewing the vid, and generally disliking EVERYTHING to do with rotaries), us that BMEP will be atrocious, the lack of 'overlap' control (? Rotary cam phasing) is the same issue as wankels, and rotor temp control point to this being just another virtual motor that won't get past (or even to?) the prototype stage.

Heh...
