More than likely its jut oil injected...that has been around for some time.
 
"Four strokes are most efficient at full throttle; with two strokes, it's the opposite,"

"...traditional two-stroke engines require oil to be mixed in with the fuel, and therefore produce higher emissions."

I always thought two strokes were better at speed and the emissions were from the excess intake scavenging fuel right out the exhaust. But what do I know? This came from an MIT publication. Must be right...
