摘要： An exhaust system for use with an engine is disclosed. The exhaust system may have a first treatment device situated to receive a flow of exhaust and convert a first constituent of the exhaust to a second constituent, and a second treatment device located downstream of the first treatment device to reduce the first and second constituents. The exhaust system may also have a sensor configured to generate a signal indicative of one of a temperature and an oxygen concentration of the exhaust, and a controller in communication with the sensor. The controller may be configured to vary the other of the temperature and the oxygen concentration based on the signal such that a desired amount of the first constituent is converted to the second constituent by the first treatment device prior to reduction by the second treatment device.

In addition, the exhaust treatment system may include a heating system configured to maintain the temperature of the catalyst above a first predetermined temperature. The heating system may also be configured to periodically raise the temperature of the particulate trap above a higher, second predetermined temperature to thereby effectuate a regeneration of the particulate trap by oxidizing particulate matter accumulated in the particulate trap.
