  • Vehicle exhaust gas treatment apparatus
    Patent number: 9133744
    Abstract: A vehicle exhaust gas treatment apparatus includes a DPF with SCR coating. An inlet piping fluidly communicates with the DPF and is positioned generally parallel to the DPF. An outlet pipe fluidly communicates with the DPF and is positioned generally parallel to the DPF. The apparatus is arranged such that exhaust gas flows through the inlet pipe in a first direction from a first inlet pipe end to a second inlet pipe end. The exhaust gas flows through the DPF in a second direction, generally parallel to and opposite to the first direction. The gas flows through the outlet pipe generally in the first direction from a first outlet pipe end to a second outlet pipe end.

  • Thermal enhancer and hydrocarbon doser
    Patent number: 9103253
    Abstract: A catalyst is positioned downstream of a thermal enhancer, such as a fuel-fired burner for example. A doser injects hydrocarbons into the thermal enhancer to maintain exhaust gas temperatures such that the catalyst is in an active condition and to raise exhaust gas temperatures to a level such that a diesel particulate filter can be regenerated.

  • Method and apparatus for directing exhaust gas through a fuel-fired burner of an emission abatement assembly
    Patent number: 8641411
    Abstract: A method of operating an emission abatement assembly includes separating the exhaust gas flow entering through the gas inlet port of the fuel-fired burner into a combustion flow which is advanced through the combustion chamber, and a bypass flow which bypasses the combustion chamber. An emission abatement assembly is also disclosed.
