Abstract

A control system and method for operating an engine includes a transition module that commands engine control from a first homogeneous charge compression ignition (HCCI) mode to a second HCCI mode. The control system also includes a fuel delivery module that operates the engine in a stratified charge operation mode after commanding engine control from the first HCCI mode to the second HCCI mode and discontinues the stratified charge operation thereafter.
