摘要： A flow management device comprises an outer chamber with an inlet arranged to receive a flow in a first flow direction and an outlet arranged to provide the flow in a second flow direction different from the first direction, and a duct arranged within the chamber, the duct having a first end configured to receive the flow from the inlet and a second end configured to release the flow towards the outlet, wherein a cross-sectional area of the duct increases towards each of the first and second ends of the duct.

摘要： An exhaust duct has a riser duct section which is connected to an exhaust port having such an inlet port at a lower portion of the riser duct section as is connected to an exhaust port for the combustion gas, the exhaust port being opened at a lower portion of the combustion box. The riser duct section extends upward along an external surface of the combustion box. Suppose that a direction normal to the external surface of the combustion box is defined as a front-to-back direction, and a horizontal direction perpendicular to the front-to-back direction is defined as a lateral direction, then the riser duct section is formed into a flat shape having a smaller dimension in the front-to-back direction than the dimension in the lateral direction. Fluctuations in width between front-side and back-side plate parts of the riser duct section are devised to be restrained, and increase in size can be avoided. The riser duct section has a rail inside the riser duct section, the rail being elongated in the vertical direction and connecting together the front-side and the back-side plate parts.

摘要： A particulate filter for a motor vehicle has a casing (2) that allows through flow. A core (4) is accommodated in the casing (2) and allows through flow. The casing (2) has a longitudinal axis (3). A through flow duct (9) is formed between the casing (2) and the core (4) to allow the through flow of exhaust gas from an internal combustion engine of the motor vehicle. A ring (7) is arranged in the through flow duct (9) and gives the through flow duct (9) a labyrinth-type configuration.

摘要： An exhaust gas pressure regulator for a combustion engine includes a regulator housing and an inner diffuser assembly arranged inside the regulator housing so that an exhaust gas flow duct is formed between an inner surface of the regulator housing and an outer surface of the inner diffuser assembly. The inner diffuser assembly includes a front portion and a regulating piston that is moveable relative to the front portion and the regulator housing between an idle position in which the exhaust gas flow duct is open, and a pressurized position in which the regulating piston at least partly closes the exhaust gas flow duct. The inner diffuser assembly includes at least one throttled flow passage between the gas flow duct and an exhaust gas pressure chamber defined by the regulating piston and an interior surface of the front portion.

摘要： A sealing device for an exhaust manifold in a vehicle having longitudinally overlapping first and second components separated by a gap includes a plurality of backing rings for positioning in the gap between the first and second components. An intumescent mat is positioned between and abuts the backing rings. A retainer connected to the first and second components covers the gap to prevent the backing rings and mat from exiting the gap while allowing for relative longitudinal and rotational movement between the first and second components.

摘要： A mobile emissions control system is provided for diesel engines operated on ocean-going ships at-berth. The emissions control system comprises two essential elements: an emissions capturing system and an emissions control system. The emissions control system may be mounted on a towable chassis or mounted on a barge, allowing it to be placed alongside ocean-going ships at-berth. The emission capturing system captures exhaust from a ship's diesel engine and conducts it into the emissions control system, which cleans the exhaust and then passes clean air into the atmosphere through an exhaust outlet.

摘要： An exhaust gas purification system for diesel engines of utility motor vehicles, includes an oxidation catalytic converter disposed in an exhaust tract, a reducing agent dosing device having a reducing agent injection device, a reducing agent decomposition device, a soot particle separator, a reduction catalytic converter and a muffler for the exhaust gases. The oxidation catalytic converter is disposed within a minimum distance directly downstream of outlet valves of the engine and a maximum distance of 0.75 m from an exhaust collecting pipe or an outlet of a turbocharger. The reducing agent decomposition device, the soot particle separator and the reduction catalytic converter are disposed separately from the oxidation catalytic converter.
