SYSTEMS AND METHODS FOR CONTROLLING AN ENGINE BASED ON AFTERTREATMENT SYSTEM CHARACTERISTICS

Abstract:

Systems and apparatuses include an a system including an engine out sensor, an exhaust sensor, and one or more processing circuits comprising one or more memory devices coupled to one or more processors. The one or more memory devices are configured to store instructions thereon that, when executed by the one or more processors, cause the one or more processors to receive the engine out sensor information from the engine out sensor, receive the exhaust information from the exhaust sensor, determine the aftertreatment system characteristic based on the exhaust information, compare the aftertreatment system characteristic to an exhaust condition, determine an acceptable input value when the aftertreatment system characteristic meets the exhaust condition, and control at least one of a fuel system actuator and an air handling actuator to achieve the acceptable input value.
