摘要：
A system comprising an injector for injecting fuel directly into the exhaust system. A control module supplies fuel using the injector to burn particulate matter in the particulate filter when the control module determines that regeneration is needed. The control module selectively supplies fuel to exercise the injector during periods when the control module determines that regeneration is not needed.
