Abstract
Methods and systems are provided for depositing one or more layers of ash on a surface of a new or cleaned gasoline particulate filter (GPF) prior to installation of the GPF in an engine and first use of the GPF. In one example, a method may include coating the GPF with the one or more layers of ash via an atomic layer deposition (ALD) technique in which two precursors react to form a layer of ash on the GPF surface.
