CA 2422188
A method and apparatus for regenerating a NOx adsorber is disclosed where the NOx adsorber is used to treat exhaust gases created during the combustion of gaseous fuels in general. A bypass line is used to maintain a target regeneration flow of exhaust gas through the NOx adsorber during regeneration regardless of operating demands on the engine. A closed and open loop control is provided. The closed loop control using sensors determining properties of the exhaust gas during regeneration and the controller using those properties to provide an efficient regeneration cycle.
