This intake apparatus for an internal combustion engine having a first bank and a second bank includes: an intake pipe including one new-air intake pipe, two branched pipes, and a junction connecting the new-air intake pipe to the two branched pipes; an EGR gas pipe connected to the junction; and a partitioning member placed around an opening in the EGR gas pipe that opens toward the intake pipe. The partitioning member defines an EGR gas storage chamber. The EGR gas storage chamber has first-bank and second-bank flow passages in which the EGR gas flows toward the first bank and the second bank. The first and second effective cross-sectional areas in the first-bank flow passage and the second-bank flow passage are smaller than the flow passage cross-sectional area in the opening of the EGR gas pipe.

A vertically extending air intake duct on a rear of a cab in a delivery vehicle to take in ambient air for an engine through an air intake has a duct body as an outer shell with the air intake on an upper portion; a side branch section on a lower portion of the body and having upper and lower ends opened in the body and outside, respectively; a mesh member extending over the air intake to collect rainwater; a louver for covering the mesh member and the air intake to prevent intrusion of matter other than ambient air; and a drip channel or bead on an inner wall of the duct body and just below the mesh member to capture and guide rainwater flowing down on the inner wall to the upper end of the side branch section.

An air conduction system includes an air collecting chamber, a first air inlet, an additional air inlet, and a buoyancy body. Air is supplyable to the air collecting chamber by said air inlets. The first air inlet has an air control valve via which the air inlet is selectively closed. The additional air inlet has an additional air control valve via which the additional air inlet is selectively closed. A buoyancy body is provided which is movable via a geodetically rising water level and which is operatively connected to a closure element of the air control valve of the first air inlet. The closure element is convertible from an open state, in which the first air inlet is fluidically connected to the air collecting chamber, into a closed state, in which said fluidic connection is interrupted, when the water level rises. The closure element comprises the buoyancy body.

A supercharging and stabilizing structure for an all terrain vehicle or a utility vehicle includes an engine body including a cylinder having an intake passage and an outtake passage. A supercharger includes a chamber having an inlet and an outlet. The supercharger further includes a duct at the inlet. An air accumulator is mounted between the cylinder and the supercharger and includes an air chamber. An input side of the air chamber intercommunicates with the outlet and the duct of the supercharger. An intake manifold is connected between an output side of the air chamber and the intake passage. When fuel is added into an engine, a control valve on the duct is closed. During fuel return or idling of the engine, the control valve is opened, and the inlet and the outlet of the supercharger, the air chamber, and the duct intercommunicate with each other to balance pressure.

The invention relates to a device for controlling the swirl of a fluid (2) flowing in a pipeline (1). The invention was based on the object of creating a device with which the adaptation of the swirl (2B) of a fluid (2) flowing in a pipeline (1), even in the case of constantly changing initial swirl (2B), to the desired flow conditions in the pipeline (1) is possible. Said object is achieved in that a swirl measuring device (4) and a swirl control device (6) are provided at predetermined positions of the pipeline (1), and the device has an evaluation and encoder unit (5), wherein, in the presence of differences between the measured actual swirl (2B) and the desired swirl, a corrective value can be determined by means of the evaluation and encoder unit (5), and the swirl control device (6) corresponds with the evaluation and encoder unit (5) and, by means of the swirl control device (6), the present swirl (2B) can be adapted to the predetermined desired swirl in accordance with the determined corrective value.

A flow splitter may include an inlet, at least two outlets, and an internal vane comprising a first end corresponding to the inlet and a second end corresponding to the at least two outlets, wherein the internal vane is configured to turn, between the first end and the second end, an internal flowing fluid from 0 degrees to a degree between about 60 degrees and 150 degrees. Methods of dividing fluid flow are also provided.

A fluid conducting system for transport of a fluid has a housing with an inlet for the fluid and an outlet for the fluid. A sensor is arranged in the housing or protrudes from an exterior into the housing and measures a mass flow or a volume flow of a fluid flow that is flowing through the housing from the inlet to the outlet. A filter element is arranged upstream of the sensor in the housing. A fluid channel section has an inlet cross section and an outlet cross section, wherein the fluid channel section is arranged upstream of and in front of the sensor and the outlet cross section adjoins the sensor. The fluid channel section has a tapering cross section tapering from the inlet cross section toward the sensor and accelerating at least a portion of the fluid flow and conducting the fluid flow to the sensor. The tapering cross section of the fluid channel section tapers constantly at least in an area of the outlet cross section in front of the sensor.

An intake structure for an internal combustion engine of a vehicle includes a cover member covering a space defined between a front side of a radiator provided in a front part of an engine room and a vehicle body opening provided in a front end of the engine room from above, and an intake duct member resting on the cover member and having an air inlet. A part of the cover member adjoining the air inlet is formed with an opening communicating the air inlet with the space, the opening defining a larger opening area in a part thereof located on a higher temperature region side of the engine room with respect to a laterally central part of the air inlet than in a part thereof located on a lower temperature region side of the engine room with respect to the laterally central part of the air inlet.

A rectification structural body includes an inlet port into which air from an air cleaner flows, an outlet port from which air flows out toward an airflow sensor, and a chamber provided between the inlet port and the outlet port. The inlet port and the outlet port are provided in such directions and at such positions that an air flow is bent in the chamber. The chamber includes two cases of a first case and a second case, the chamber being divided into the two cases.

A control device for an internal combustion engine includes an intake channel, an exhaust gas recirculation channel which enters into the intake channel, a control element, a mixing housing which forms the intake channel, a connection element, a compressor, and a shaft. The mixing housing has a mouth of the exhaust gas recirculation channel in a lower area, an outlet, a mixing housing section, and a bowl-shaped recess. The cross-sectional extension is formed via the mixing housing to provide an axial stop face. The connection element abuts against the axial stop face and is radially limited by an axially opposite inner wall surface on the stop face. The mixing housing section has a recess arranged at the lowest point of the mixing housing section and below the axially opposite inner wall surface. The recess enters into the bowl-shaped recess of the mixing housing.
