  • Method and apparatus for supplying air to emission abatement device by use of turbocharger
    Patent number: 7464539
    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.
