Abstract
A control system and method for operating an engine includes an HCCI mode control module operating an engine in a homogeneous charge compression (HCCI) mode. The control system also includes a difference module determining an actual difference between a desired torque amount and a spark ignition (SI) threshold. An SI mode control module operates the engine in a SI state when the actual difference is above a threshold band. A HCCI mode control module operates the engine in the HCCI mode for a predetermined time when the actual difference is within the torque threshold band. The HCCI mode control module operates the engine in the HCCI mode when the actual difference is below the torque threshold band.
