摘要： An apparatus and system are disclosed for efficiently recirculating an exhaust gas in a combustion engine. The apparatus (100) includes an intake air conduit (204) that accepts and promotes mixing of an intake air stream (112) and an EGR stream (107). The intake air stream moves in the direction of the axis of the intake air conduit. The EGR stream enters the intake air conduit within a volute (205) of decreasing area curled about the outside circumference of the intake air stream. The rate at which the volute encourages mixing of the EGR stream with the intake air stream is affected by the rate at which the volute's area decreases as the volute curls about the inside circumference of the intake air conduit, and by the angle of entry (212) for the EGR stream as directed by the volute.

摘要： An apparatus, system, and method are disclosed for reducing nitrogen oxide emissions in a combustion engine. In one embodiment, the method includes a shift detection module (202) determining an out of gear (OOG) indicator (204) for a manual transmission (104). The method further includes an engine speed module (214) determining an engine speed target (216) based on at least one operating condition (206) of the engine. The method continues with a load determination module (224) determining an engine load target (226) in response to the OOG indicator and an engine acceleration module (220) determining a desired net torque (222) based on the engine speed target and the engine load target. Finally, the method concludes with an emissions module (207) determining a minimum fuel target (208) based on the desired net torque and an actuation module (230) generating a fueling signal (242) to engage an engine fueling.
