Turbo-compound recovery
Exhaust from all three chambers feeds a helical gallery into a radial turbine. Planetary reduction dumps leftover shaft work into the eccentric — not overboard.
Ceramic thermal barrier
A thin TBC on the rotor flanks holds combustion heat in the gas. Less jacket loss, higher expansion work, cooler oil.
Epitrochoid + 3:1 gearing
A two-lobe housing and tri-flank rotor give three power pulses per rotor turn. The eccentric shaft turns 3× faster — smooth like a six.
Variable geometry turbo
VGT vanes keep the compressor on the efficiency island from cruise to redline instead of dumping energy through a wastegate.
Hydrogen lean burn
Fast flame speed and a high gamma let the map run lean at high CR without knock. Near-zero tailpipe CO₂ on green H₂.
DLC apex seals
The classic rotary leak path. Diamond-like carbon on the seals cuts friction and blow-by that used to kill Wankel efficiency.
