Abstract
A vehicle, engine controller and method for coordinating direct split injection of two or more pulses of fuel during a working cycle of a reactivated cylinder which was deactivated in a previous working cycle is described. By using split injection for the reactivated cylinder, the particulate matter and particulate number (“PM/PN”) generated by the reactivated cylinder is reduced.
