Abstract

An exhaust after-treatment system that is configured to treat an exhaust produced by an engine, and includes a bypass passage including an inlet for receiving an amount of the exhaust from an exhaust passage. A first exhaust treatment component is located within the bypass passage, and a valve is located proximate the bypass passage that is configured to control the amount of the exhaust that enters the inlet of the bypass passage. A second exhaust treatment component is located in the exhaust passage downstream from the inlet of the bypass passage, wherein an outlet of the bypass passage communicates the exhaust treated by the first exhaust treatment component back to the exhaust passage at a location that is downstream from the second exhaust treatment component such that the exhaust treated by the first exhaust treatment component does not interact with the second exhaust treatment component.
