ABSTRACT:
A diesel exhaust aftertreatment device regeneration system includes an exhaust conduit adapted to conduct exhaust gas to an exhaust gas aftertreatment device. The system further includes a low pressure bottom feed fuel injector having an inlet portion fully received within a chamber of an adaptor housing having a lower portion attached to the exhaust conduit. The housing is provided with fuel flow openings to allow low pressure fuel to circulate around and cool the fuel injector inlet portion within the chamber. Fuel injected into the exhaust conduit is preferably targeted toward a vaporization member, within the exhaust conduit, operative to absorb heat from the exhaust gas and vaporize fuel deposited thereon. A plurality of inwardly extending mixing baffles within the exhaust conduit intermediate the vaporization member and the aftertreatment device extend the mixing path to improve fuel vaporization for assisting regeneration of the device.
