ABSTRACT:
A control system for an engine comprises an air per cylinder (APC) generating module that generates measured and desired APC values. A combustion transition module selectively transitions the engine from spark ignition (SI) combustion to homogeneous charge compression ignition (HCCI) combustion and from HCCI combustion to SI combustion. A spark control module selectively retards spark during the transitions based on a ratio of the measured APC value and the desired APC value. Alternately, spark retard can be based on measured and desired engine torque representing values (ETRVs).
