    摘要： A method of detecting failure of a substrate in a particulate filter includes comparing an absolute value of a difference between a theoretical temperature difference and an actual temperature difference between an upstream end and a downstream end of the particulate filter to a temperature differential threshold, and comparing an absolute value of a difference between a theoretical pressure difference and an actual pressure difference between the upstream end and the downstream end of the particulate filter to a pressure differential threshold. Failure of the substrate is indicated by one or both of the temperature difference and the pressure difference being greater than the temperature differential threshold and the pressure differential threshold respectively.

    摘要： A system for a sequential turbocharger includes a loop control module, a set-point module, and a loop operation module. The loop control module generates a loop control mode signal based on an engine speed signal and an engine load signal. The loop control mode signal indicates one of a single-loop control mode and a dual-loop control mode. The set-point selection module determines at least one of a boost pressure set-point value and an exhaust pressure set-point value based on the loop control mode signal, the engine speed signal, and an engine torque signal. The loop operation module operates at least one of a variable geometry turbine and a bypass valve of the sequential turbocharger during the single-loop control mode based on the boost pressure set-point value, and during the dual-loop control mode based on the boost pressure set-point value and the exhaust pressure set-point value.
