Displacement on demand

Interesting discussion, but NoDOHC is right. Even diesel engines without throttle plates are giving lowest BSFC at almost full load. Load is essential.

Very late closing timing of intake ports could push quite large portion of fresh mixture back to intake allowing for more load and effectively make atkinson cycle with uneven compression - expansion, but we know that piston engines doing this are using high static CR, not option for rotary...
