  • Flow hood assembly
    Patent number: 11274582
    Abstract: A flow hood assembly for an engine aftertreatment system having a particulate filter and a selective catalytic reduction device is disclosed. An outer case defines a cavity, the outer case having an inlet and an outlet formed therein, and a neck section formed between the inlet and the outlet. A socket in the outer case is in an opposed relationship to the outlet and is shaped to receive an injector that introduces a reducing agent into the flow of exhaust gases. A baffle reduces a cross-sectional area of the cavity at the neck section to increase exhaust gas velocity at a sensor positioned at the neck section. A deflector member in the cavity between the baffle and the socket directs a portion of the exhaust gases towards the socket and across the injector nozzle.

  • Compressor recirculation into annular volume
    Patent number: 11261873
    Abstract: To solve the problems of compressor wheel blade flow separation causing surge type noises when an exhaust gas recirculation (EGR) duct introduces into the compressor exhaust gases to be returned to the engine, the exhaust gas is fed into an annular volume, defined between inner and outer walls or an annular transition cavity shaped as a radially expanded, axially flattened cylindrical space in the compressor inlet, so that the generally unidirectional radial flow from an EGR duct is re-directed and organized as it is turned from generally radial to generally axial, merging with the general inlet flow and presenting the compressor wheel with airflow of “circumferentially uniform” flow velocity.
