So you are saying that more air in the engine the better the mpg, well then why not have a big engine that sucks a lot of air in and that should get better mpg than a small engine that sucks less air in at a given output. I still don't follow the logic, since at partial throttle there is more excess air in a Diesel and less fuel but yet the sbfc is not better.
In the report that you site, they don't mention changing the injection timing for optimum torque at the different temperatures tested.
