Abstract
An engine system and method for operating an engine that includes a particulate filter is described. In one example, spark delivery to one or more engine cylinders is ceased while fuel is continued to be injected to the one or more cylinders to improve particulate filter regeneration. The system and method may be particularly beneficial for direct injection turbocharged engines.
