    摘要： Systems and methods are provided for engine systems including a multiple tap aspirator with a throat tap and a diffuser tap. Suction passages coupled to the throat and diffuser taps, respectively, may fluidly communicate via a leak passage with a flow restriction. During conditions where the pressure at a suction flow source of the diffuser tap is less than the pressure at the diffuser tap, backflow from the diffuser tap may travel through the leak passage into the throat tap.

    摘要： A compressor (5) of a turbo supercharger (3) is located between an air flow meter (12) and a throttle valve (13). An EGR passage (21) is connected to an intake passage (10) at a joint (22) upstream of the compressor (5). The following relationship (1) is satisfied between an intake passage volume (V1) from the air flow meter (12) to the junction (22), an intake passage volume (V2) from the compressor (5) to the throttle valve (13) and a maximum boost pressure (Pb) under operating conditions in which the introduction of EGR gas is performed, in order to prevent a mixed gas of fresh air and EGR gas from flowing back to the air flow meter (12) even under the maximum boost pressure (Pb). V 1 > V 2 × ( P b - P 1 P 1 ) × ( P 1 P b ) κ - 1 κ ( 1 )

    摘要： A turbocharger system includes a flexible duct having an elongated elastomeric body extending longitudinally between first and second ends configured to attach to respective turbocharger devices. A plurality of constricting rings are spaced longitudinally between the ends. Each constricting ring applies a radial compression force around a respective circumference of the duct. Each ring is comprised of a molded thermoplastic retained in a concentric shape by a clasp. The spacing of the constricting rings has a density sufficient to limit a volume increase of the duct under turbocharger operating pressure to less than 20%.

    摘要： Systems and methods are provided for engine systems including a first multiple tap aspirator with a motive inlet coupled to an intake upstream of an air induction system throttle and a mixed flow outlet coupled to an intake manifold, and a second multiple tap aspirator with a motive inlet coupled to the intake upstream of a main throttle and a mixed flow outlet coupled to the intake downstream of the air induction system throttle. During non-boost conditions, intake air may be selectably diverted around a compressor and through the first and/or second aspirator based on desired vacuum generation. During boost conditions, the first and second aspirators may function as compressor bypass valves, and intake air may be selectably directed from downstream of the compressor to upstream of the compressor via the first and/or second aspirator based on a desired compressor bypass flow.
