METHOD AND SYSTEM FOR IMPROVING EFFICIENCY OF A PARTICULATE FILTER

An engine system and method for operating an engine that includes a particulate filter is described. In one example, soot loading of a green particulate filter is increased to improve efficiency of the green particulate filter. The soot loading of the green particulate filter may be expedited so that by the time a vehicle reaches a customer or testing facility, the green particulate filter may be operating at a desired efficiency level.
