摘要： An emissions control system comprises a temperature determination module and an emissions control module. The temperature determination module determines a first temperature of a heater element of a diesel particulate filter (DPF) assembly in an exhaust system and determines a second temperature of a catalyst of the DPF assembly. The emissions control module selectively activates the heater element, selectively initiates a predefined combustion process in an engine based upon the first temperature, and selectively starts a reductant injection process based upon the second temperature.

摘要： A control system includes a temperature module that determines a temperature of a selective catalytic reduction (SCR) catalyst, a derivative module that determines a derivative of the temperature, and a dosing module that regulates a dosage of a reductant supplied to the SCR catalyst to regulate an engine out NOx level. A control module generates control signals based on the temperature derivative, wherein the control signals regulate an amount of reductant accumulated within the SCR catalyst to reduce reductant release from the SCR catalyst during thermal transients.
