Abstract
Systems and apparatuses include an engine, an aftertreatment system including a catalyst, and a controller coupled to the aftertreatment system and the engine. During a warmup period for an engine, the controller determines a value regarding a mass flow rate of exhaust gas based on information received from at least one of the engine or the aftertreatment system. The controller receives a target value regarding the mass flow rate of the exhaust gas. The controller controls at least one of the engine, the aftertreatment system, or at least one component associated therewith to reach or attempt to reach the target value regarding the mass flow rate of the exhaust gas.
