    Abstract: A fuel injector for an exhaust heater includes a cover and an air blast nozzle. The cover has a nozzle seat, a fuel inlet, and an air inlet, the nozzle seat arranged along a flow axis. The air blast nozzle is seated in the nozzle seat and has a unibody. The air blast nozzle unibody is in fluid communication with the fuel inlet and the air inlet arranged along the flow axis to port fuel and air into a combustion volume, e.g., to heat a stream of exhaust gas flowing between an engine and a catalytic reactor by combustion with fuel introduced through the fuel inlet and air introduced through the air inlet.

    Abstract: A pressure atomizing nozzle for injecting fuel includes an inlet housing configured to thermally isolate the interior space from external conditions and to remain relatively cool under operation so as to substantially eliminate heat soak back from the inlet housing to the interior space thereof after operation. First and second coolant conduits cool the nozzle tip region actively during operation and passively after operation. A cooling air jacket is configured to thermally isolate inboard components from exterior conditions, to provide clean air during operation to the nozzle tip region for diluting carbon to reduce carbon deposits in the nozzle tip region and for cooling the same, and to provide passive cooling to the nozzle tip region after operation.

    Abstract: A flow directing apparatus for directing fluid flow includes a flow body defining a bore therethrough configured and adapted to direct fluid flowing therethrough. The bore includes an outlet and an opposed inlet with an enlargement, formed as a countersink and/or a chamfer using a suitable boring device. The enlargement is configured and adapted to reduce sensitivity to entrance-edge conditions for the bore.
