Processes and devices for regenerating a gasoline particulate filter utilized in filtering an exhaust stream of a direct-injection gasoline engine operating at substantially stoichiometric conditions include introducing an amount of oxygen into the exhaust stream downstream of the engine and upstream of the gasoline particulate filter, and regenerating the gasoline particulate filter by passing the exhaust stream enriched with the amount of oxygen through the gasoline particulate filter.
