DFCO does NOT deactivate cylinders - or if you prefer, DFCO does not deactivate valves.
During DFCO (and powertrain braking), valves open and close normally,
like it's been done since the 50s, or whatevar.
It's merely FUEL that is not being used during DFCO.
I suppose DFCO could be combined with cylinder deactivation,
but wouldn't that be past the point of diminishing returns?
If you're already not injecting any fuel into any cylinders (DFCO),
you're already using zero fuel.
What additional benefit would there be to also deactivating the valves while ALREADY using zero fuel?
