Method and apparatus for supplying air to emission abatement device by use of turbocharger

An apparatus, comprising:

• a combustion engine,
• an emission abatement device comprising a burner to burn particulate matter trapped by a particulate filter of the emission abatement device, the burner fluidly coupled to the engine to receive exhaust gas therefrom, and
• a turbocharger comprising an air compressor that is fluidly coupled to the engine to supply pressurized air to the engine and that is fluidly coupled to the burner of the emission abatement device via a flow path not including any combustion section of the engine to supply pressurized air to the burner of the emission abatement device.

An apparatus, comprising:

• an emission abatement component,
• a thermal regenerator configured to receive exhaust gas of a combustion engine and to generate heat for regeneration of the emission abatement component, and
• a turbocharger comprising an air compressor fluidly coupled to the thermal regenerator via a flow path not including any engine combustion section to supply pressurized air to the thermal regenerator.
