Cool

2 stroke! This would have to be a Direct Injection 2-stroke to be emissions worthy and fuel efficient. On another note Direct Injection has really rekindled 2 stroke engines. I think the last time 2-strokes were considered was in the '90s when Direct Injection was being introduced. With Atkinson cycle and 2 stroke the output would be almost the same as a similar sized 4-stroke Otto or should I say a 4 stroke Diesel, correct? With all of this ICE development going one I wonder what this could mean for Battery Electric Vehicles?

So this means output isn't changing per liter but efficiency is. Sounds great!
Atkinson cycle usually requires a higher compression ratio to be effective so with Direct injection we're talking even higher compression.
