  "textContent": "A method for regenerating a DPF (24) in an exhaust aftertreatment system (20) includes the steps of: monitoring a temperature of exhaust associated with a DOC (22); retarding an injection of fuel into at least one combustion cylinder (14), and thereby intentionally causing a misfire in the at least one combustion cylinder (14), dependent on the monitoring step; increasing an outlet temperature of the exhaust from the DOC (22) to a first threshold temperature; and oxidizing particulates within the DPF (24) when the exhaust is at the increased temperature. The number and/or frequency of the misfires is controlled to provide the desired exhaust temperature at the DPF inlet.",
