No poppet valves. No camshafts. No rockers. No springs. No pulleys. No timing belts. No more bulky cylinder head.
Patented Rotary Valve Control Technology for Piston Engines

Minimalistic and Feature Dense
Cylinder head re-invented.
The only valve control technology to offer the highest number of features in a low-profile, minimal cylinder head design.

Valves with purpose
Rotation vs. reciprocation.
Innovative, simple rotary design to improve the main function of opening and closing the air canals with higher capacities.

No mechanical shenanigans
Fixed stroke-length VCR
Multi-volume discretely Variable Compression Ratio without any mechanical complexity, instantly, from low to very high ratios.

Reduced Exhale Resistance
RPMs to the pistons
The intake can be pressurized, but not the exhaust. Bigger exhaust ports mean faster exhale and all the good that comes with it.

Behavior Independence
Electronic actuation
Independent timings of valves and separation of cylinders to allow optimal engine function under different driving conditions.

Secondary fuel option
Runtime fuel switching
Depending on the driving condition, ECU can instantly switch between a higher or lower energy density fuel type.
