Abstract:
Methods and systems are provided for regenerating an exhaust particulate filter during an engine non-combusting condition. In one example, a method may include, responsive to a higher than first threshold soot load on the PF and a higher than threshold PF temperature, regenerating the PF by flowing compressed air through the PF via operation of an electric booster coupled to the intake manifold.

Claim (Index 18):
A system, comprising:\n a controller with computer readable instructions stored on non-transitory memory to control the following when an engine coupled to a vehicle is not combusting fuel and air: estimate a particulate matter (PM) load on a particulate filter (PF) housed in an exhaust passage of the engine via a differential pressure sensor coupled across the PF; estimate an exhaust temperature via a temperature sensor coupled to the exhaust passage upstream of the PF; in response to each of the PM load being higher than a threshold load and the exhaust temperature being higher than a threshold temperature, opening each of an intake throttle, an exhaust gas recirculation (EGR) valve housed in an EGR passage coupling an exhaust manifold to an intake manifold, and a wastegate valve housed in a wastegate passage coupled to the exhaust passage from upstream of an exhaust turbine to downstream of the exhaust turbine, and operating a motor-driven electric compressor housed in a conduit coupled to an intake passage for a duration to route compressed air to the PF for regeneration.
