Abstract: A method of operating an emission abatement assembly includes supplying a first flow rate of fuel to a fuel-fired burner to generate heat to combust soot trapped in a particulate filter. The method further includes supplying a second flow rate of fuel to the burner in an attempt to increase the temperature of the heat with the second flow rate of fuel being greater than the first flow rate of fuel. The method further includes determining the temperature of the heat. The method further includes supplying a third flow rate of fuel to the burner if the temperature of the heat decreases in response to supplying the second flow rate of fuel with the third flow rate of fuel being less than the second flow rate of fuel. An associated emission abatement assembly is also disclosed.

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.
