ABSTRACT:
A system and method to provide a desired torque increase from an engine in which some cylinder operate in spark ignition (SI) combustion mode only and some cylinders operate in homogeneous-charge, compression-ignition (HCCI) combustion mode only are disclosed. Such method includes: operating a first portion of engine cylinders in homogeneous charge compression ignition combustion mode while a second portion of engine cylinders are deactivated. The second portion of engine cylinders in spark ignition combustion mode is activated when a torque demand is greater than the first portion of engine cylinders is capable of supplying. Also, the second portion of engine cylinders is activated when a rate of torque demand is greater than the first portion of engine cylinders is capable of supplying.
