Abstract
A method for a vehicle comprises responsive to installation of a new exhaust particulate filter, doping fuel with an ash-producing additive, and combusting the doped fuel to produce ash, wherein the ash deposits as an ash coating on the new exhaust particulate filter. In this way, a filtration efficiency of an exhaust particulate filter can be increased quickly as compared to a filter with no deposited ash coating, inexpensively as compared to conventional methods using membranes, and with a lower back pressure drop as compared to conventional methods.
