They might be trying to just get their research efforts documented in patents. Not sure exactly why, maybe trying to capture equipment if someone wants to make a supercharged chainsaw? XD

A two stroke light small engine burning synthetic fuels on a small package could be a nice alternative to heavy battery filled vehicles.
I just started watching the IMSA series (Made it to the Rolex 24 just a couple of weeks ago, freaking coldddd) and Mazda did pull out last year, I wander if they're thinking of re-entering with a 2 stroke? I know a friend of mine mentioned that they re-did the rules a bit to allow some wiggle room for a rotary, but maybe this is what they're adjusting for?

Interesting.
I'm going to have to start paying attention to that.

Just talked to a buddy, I guess SC are pretty much banned in most open and closed circuit motorsport now? So not sure about my theory anymore. They could be trying a turbocharged or e-turbocharged 2-stroke?
A lot of speculation though.
I'm thinking maybe aviation/UAV. Small, light, uses common fuel, supercharger for altitude. I don't know why Mazda would play in that industry but it's not an obvious problem to solve. Turbofan powered drones are cheap relative to a manned jet or satellite, but they're not cheap relative to anything else.
I wonder if dirt bike / motorcycle markets are booming in China and Japan, and they want in on the action?
Idk.
Paris is moving to ban motorcycles, but not because of emissions pollution, but noise pollution.
Then again Parisians like to eat outside a lot, and in China you can see the air, so they probably don't eat outside as much.

theres lots of home built aircraft that use a rotary engine for a powerplant. my brother was thinking about building one a few years ago
I think many people are viewing this as a new version of a 'two stroke' engine we all know and hate....
It's more like an efficiency-optimized diesel.
The most powerful diesels in the world are 'two strokes' because they have twice as many power strokes (duh!) and all have forced aspiration.
This engine uses diesel ignition when most efficient, with backup spark ignition for other modes.
It has no premixed-oil fuel or sacrificial lubrication, so no blue smoky exhaust emissions, and uses the exact same sump and oil pump as 'normal' engines.
The valves remove the fixed timing of the old port system, allowing for varying charge volumes, improved scavenging and reduced fresh charge losses - even to the point of achieving Miller cycle efficiencies.
This design, coupled with new direct gasoline injection improvements, is by no means 'your old chainsaw motor'.
