Fuel Reformer for De-NOx Trap

摘要

An emissions control system for an engine of a machine includes an exhaust conduit carrying a flow of exhaust gas from the engine, a de-NOx catalyst disposed along the exhaust conduit and configured to treat the flow of exhaust gas, a fuel reformer module configured to provide a gas stream containing hydrogen gas and carbon monoxide gas, and a junction disposed along the exhaust conduit between the engine and the de-NOx catalyst, the junction being arranged to mix at least a portion of the gas stream with the flow of exhaust gas such that the hydrogen gas and the carbon monoxide reach the de-NOx catalyst and act as reductants to regenerate the de-NOx trap.
