While we are talking about DFCO, each manufacturer is going to have their own method of cutoff or reduction; the thermodynamic properties of different engines require that some maintain a combustion cycle while others do not. Some modern engines turn their injector pulse width down down to like .0002 while coasting (Hyundai Genesis). This means there is SOME amount of fuel being supplied to the cylinders, though a microscopic amount. Lets not lump all modern fuel injection systems together, because some are in fact slightly different.
Thanks to everyone for their responses!
I am learning a lot.
