Abstract:
A system includes a temperature sensor configured to measure a temperature of exhaust gas produced by an engine, and a boost error module configured to determine a boost error of the engine. The system further includes a combustion control module configured to select at least one of a target boost pressure of the engine, a target EGR flow rate of the engine, and a target fuel injection parameter of the engine from a first set of target values when the exhaust gas temperature is less than a predetermined temperature and the boost error is less than a predetermined value, and to select the at least one of the target boost pressure, the target EGR flow rate, and the target fuel injection parameter from a second set of target values when the exhaust gas temperature is less than the predetermined temperature and the boost error is greater than the predetermined value.
