Method and apparatus for supplying air to emission abatement device by use of turbocharger
First Claim
1. A method, comprisingoperating 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.

Abstract
An apparatus comprises a combustion engine, an emission abatement device, and a turbocharger. The emission abatement device is fluidly coupled to the engine to receive exhaust gas therefrom. The turbocharger comprises an air compressor that is fluidly coupled to the engine to supply pressurized air to the engine and that is fluidly coupled to the emission abatement device via a flow path not including any combustion section of the engine to supply pressurized air to the emission abatement device. An associated method is disclosed.
