| 1. A method, comprising
operating a turbocharger so as to advance pressurized air (i) from the turbocharger to a combustion engine and (ii) from the
turbocharger to a thermal regenerator of an emission abatement device via a flow path not including any combustion section
of the engine;
advancing exhaust gas to the thermal regenerator; and
advancing heated exhaust gas from the thermal regenerator to a particulate filter of the emission abatement device to burn
particulate matter trapped by the particulate filter.
