No emission data for this engine.
However it works similar to 2 stroke piston engines and we all know those have issues with liner lubrication and more importantly, emission. Except that this has positive scavenging as compared to true 2stroke pistons
But it will require hi RON fuel due to its high compression ratios.
It could work as industrial power plants as specific output is high esp using diesel.
But knowing LTA that anal dept will never allow it in SG
This rotary engine is slightly more novel as the apex seals are stationary and on the liners itself. Also for every rotation of the rotor, there is actually 3 power strokes compared to Mazda rotary engine.
Finally I think emissions can be tweaked using excess cooling air thought the engine.
I am impressed with this engine
The mazda should look into this as mazda working on hydrogen to bypass the emission problem.
But this new rotary has three times the power due to three power stroke.
