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.
