  • Dual air circuit for exhaust gas treatment
    Patent number: 8991157
    Abstract: An exhaust treatment system for an engine includes a regeneration device being in receipt of exhaust from the engine and positioned upstream of a diesel particulate filter. A compressor provides a source of compressed air. An air/fuel nozzle is coupled to the regeneration device, in receipt of a fuel supply as well as the compressed air. The fuel and compressed air are forced through an orifice of the nozzle to atomize the fuel. A bypass line provides compressed air from the compressor to the regeneration device without passing through the orifice of the nozzle. A valve is operable to allow compressed air to flow through the bypass line when a predetermined condition exists.
    Type: Grant

  • Semi-tubular vane air swirler
    Patent number: 8590864
    Abstract: A semi-tubular vane air swirler is provided. In one embodiment the air swirler is a deep drawn sheet metal component having a first and a second set of semi-tubular vanes formed therein. In one embodiment the semi-tubular air vanes include a first and a second portion formed by upsetting the sheet metal in opposing directions to create mirrored vane geometry, thereby doubling the open area of the vane.
