I think you need to read a book about internal combustion engines. This made me lol.
Don't worry I read them all.
So, are you saying that Honda's CVCC, HX engines and that three cylinder in the 1st generation Insight would get better economy at lambda=1 rather than running very lean mixture in cruise?
Or that Atkinson cycle is in fact a load of cr*p?
Or cylinder deactivation is just an Illuminati plot to actually increase fuel consumption of gasoline engines?
Because all of these (among other things) do exactly what I described in my post and you found so entertaining.
I guess that lot of OEM engineers employing this "bogus" technology could also benefit from picking up a book then
