A compressor arrangement for an internal combustion engine, including a compressor which is located in a compressor housing and has a low pressure side and a high pressure side, and includes a vacuum supply device which has: a propellant channel which has a nozzle and is fluidically connected on one side via a propellant inlet connection to the high pressure side of the compressor and on the other side via a propellant outlet connection to the low pressure side of the compressor; and a vacuum channel opening into the propellant channel fluidically between the propellant inlet connection and the propellant outlet connection.

A body structure includes a generally trough-shaped first structural member having a floor, two opposed side walls having respective top edges, and an open top along a length of the first structural member defining a generally U-shaped cross-section. The first structural member has a first portion with a first flow direction therethrough and a second portion with a second flow direction therethrough different from the first flow direction, the first portion having opposed first and second ends with a first opening in the first end, the second portion having opposed third and fourth ends with a second opening in the fourth end, wherein the second and third ends are in fluid communication with each other. The first portion has a first average depth and the second portion has a deepened portion having a second average depth larger than the first average depth.

An engine component includes an intake manifold of stratified layers defining a plurality of runners each having a gas outlet leading to a cylinder head, and a plenum including partial walls forming channels radiating from a common gas inlet extending into a gooseneck conduit having an incorporated positive crankcase ventilation (PCV) apparatus. The gooseneck conduit transitions into the channels and runners such that there is no seal between the gooseneck, plenum, and runners.

A motorcycle intake air guide for guiding an intake air volumetric flow from a front region of a motorcycle to a motorcycle internal combustion engine includes a front air guiding duct, a rear air guiding duct arranged downstream of the front air guiding duct, and a steering head bypass region arranged between and connecting the front and the rear air guiding ducts to one another. The front and the rear air guiding ducts have a closed profile. The steering head bypass region preferably has, in a steering head cross-sectional plane which is arranged orthogonally with respect to a main flow direction of the intake air volumetric flow in the steering head bypass region, a non-closed profile for guiding the intake air volumetric flow around a steering head recess through which a steering head of the motorcycle extends. The steering head may close the non-closed profile at the steering head recess.

Methods and systems are provided for a convolute-swirl integrated duct (CSID). In one example the CSID may be configured to comply with engine roll and induce swirl in an intake air flow. Engine roll is absorbed as a result of a positioning of the CSID along an intake passage upstream of a compressor inlet and pre-whirl is introduced to intake air prior to delivery of the intake air to a compressor.

A compressor arrangement for an internal combustion engine, having a compressor which is arranged in a compressor housing and has a low pressure side and a high pressure side, and having a negative pressure provision unit, which has a propellant channel that is fluidically connected, on the one hand, via a propellant inlet fitting to the high pressure side of the compressor and, on the other hand, via a propellant outlet fitting to the low pressure side of the compressor and has a nozzle, and which has a negative pressure channel opening into the propellant channel fluidically between the propellant inlet fitting and the propellant outlet fitting.

A charge air line of an internal combustion engine for supplying multiple cylinders of a cylinder bank of the internal combustion engine arranged in-line with charge air, has multiple charge air line sections. Emanating from each charge air line section a branch leads to a cylinder, the branch screwable to a cylinder head of the respective cylinder. The charge air line has an upstream end, via which charge air is feedable to the charge air line, and a downstream end, which is closed by an end cap. At the downstream end, the charge air line has a larger flow cross section than at the downstream end.

A partition plate is configured to separate an intake passage formed by an intake pipe to be coupled to a combustion chamber into a first intake passage and a second intake passage. The first intake passage is openable and closable by a valve. A shape of a first cross section orthogonal to an extending direction of the intake pipe is set on the basis of a shape of a surface of the intake pipe that faces the partition plate with the second intake passage interposed therebetween.

An engine component includes an intake manifold of stratified layers defining a plurality of runners each having a gas outlet leading to a cylinder head, and a plenum including partial walls that form channels radiating from a common gas inlet and transitioning into the runners such that there is no seal between the plenum and runners. The partial walls form endoskeletal structure configured to support the intake manifold.

Embodiments of apparatus for controlling the movement of matter, including but not limited to one-way fluid valves, are disclosed. The apparatus may include a transition nozzle, a funnel nozzle, and a reverse flow blocker arranged in series in a case. A counter-flow area may be disposed about the funnel nozzle. The apparatus may permit matter to flow in a first direction, and discourage or prevent flow in a direction reverse to the first direction. Control over the flow of matter may also enable the matter to be harvested, sorted, separated or combined with injected matter.
