Regarding sustainability thinking look an see this Mazda work.
Instead inventing the wheel they are trying to extend marvelus efficiency of large 2 stroke diesel turbocharger in tiny engine design for vehicles.
Idea is having high pressure on intake side with mechanical compressor and controls phase for exhaust and intake cams that reduce mix in cylinder.
Today possible with easy electric control available.
Engine will have transition from self injection “like diesel” to spark drive when engine load will increase.
I think “speculation” can reach close to 40-50% efficiency.
Looking forwards to testing- thanks Mazda for grate work with thinking in driving seat.
