Abstract
An exhaust system for use with an engine is disclosed. The exhaust system may have a first treatment device configured to receive a flow of exhaust from the engine and convert a first constituent of the exhaust to a second constituent. The exhaust system may also have a second treatment device located downstream of the first treatment device and configured to reduce the first constituent and the second constituent. The exhaust system may further have a flow regulator configured to selectively vary a rate of exhaust passing through the first treatment device, and a controller configured to operate the flow regulator such that a desired amount of the first constituent and the second constituent is received by the second treatment device.
