    摘要： An inertial gas-liquid impactor separator includes an inertial impactor collector having an impactor surface extending diagonally relative to axially accelerated flow, which surface is preferably a cone having a leading tip axially facing and axially aligned with the acceleration nozzle. In a further aspect, first and second inertial impactor collectors are provided in series, with an orifice in the first inertial impactor collector providing a nozzle for the second inertial impactor collector. Improved performance is provided by reducing the extent of the stagnation region to change from a narrow band particle size range to a wider band range and to shift cut-off size. An inertial gas-liquid impactor separator has a perforated layer of coalescence media having at least one aperture through which the gas-liquid stream flows. Improved performance is provided by increased penetration of the flow into the media patch and thereby enhancing particle capture by interception, impaction and diffusion.

    摘要： According to one representative embodiment, an aspirator for cooling exhaust gas from an internal combustion engine includes a nozzle section, an expansion section, and an air entrainment section. The nozzle section is communicable in exhaust receiving communication with the internal combustion engine. The nozzle section includes a plurality of nozzles through which an exhaust gas stream is flowable. The expansion section is communicable in exhaust receiving communication with the plurality of nozzles. The air entrainment section is communicable in air supplying communication with the expansion section. The air is mixable with the exhaust gas within the expansion section.
