Abstract: A fluid-conduit collector spans across a plurality of collector-inlet interface structures and at least one fluidic diode element. A branch inlet portion of at least one collector-inlet interface structure, in fluid communication with a corresponding fluid-conduit runner portion, provides for receiving exhaust gases from a corresponding separate exhaust port of an intermittent-combustion internal combustion engine. A main inlet portion of the collector-inlet interface structure in fluid communication with an outlet portion thereof defines a portion of the fluid conduit of the collector. The branch inlet portion is in fluid communication with the outlet portion via a collector inlet port that is at least partially bounded by a relatively-sharp-edged junction with the fluid conduit of the collector.

Abstract: A fluid-conduit collector (20, 20.x, 20a, 20b) spans across a plurality of collector-inlet interface structures (24, 24.1, 24.2, 24.3, 24?, 24?) and at least one fluidic diode element (26, 26.1, 26.2, 26.3, 26?, 26?). A branch inlet portion (20??, 20.1??, 20.2??, 20.3??) of at least one collector-inlet interface structure (24, 24.1, 24.2, 24.3, 24?, 24?), in fluid communication with a corresponding fluid-conduit runner portion (14, 14.x), provides for receiving fluid from a source of fluid (12). A main inlet portion (20.x?) of the collector-inlet interface structure in fluid communication with an outlet portion (20.x?) thereof defines a portion of the fluid conduit of the collector (20, 20.x, 20a, 20b). The branch inlet portion (20??, 20.1??, 20.2??, 20.3??) is in fluid communication with the outlet portion (20.x?) via a collector inlet port (56?, 106) that is at least partially bounded by a relatively-sharp-edged junction (60) with the fluid conduit of the collector (20, 20.x, 20a, 20b).
