I ain't near edumacated enough to follow all that graph stuff, but, I suspect that this is not such a good idea.
Yes, pumping losses go down as you now have an engine that is running like crap and you have to open the throttle further, but, you also have lost the benefit of getting power out of cylinders that are every bit as much a drag for 3/4 of the combustin cycle as they were when they were firing.
I do wonder if this idea might work given sophisticated enough engine control. What I mean is that lets say every X cycles a lean shot is applied followed immediately by a blank cycle. The lean firing got things a little warmer than normal, the dud then cools it off.
I suspect this causes emissions issues, but might be a way of getting the benefits of lean burn without melting holes in your pistons.
