An arc-shaped recess part is provided at a collective pipe of an exhaust manifold, whereby a flow of exhaust gas from one end side of cylinders is uniformized and then introduced into an exhaust-gas purifying device.

A vehicle exhaust system includes a hot end having one or more hot end exhaust components that treat emissions generated by an engine and a cold end that includes at least one cold end component that attenuates noise. At least one acoustic volume is in parallel or serial to the hot end to further attenuate noise.

A sound generating assembly for an exhaust system of an internal combustion engine of a motor vehicle includes a sound generator arranged within a sound generator housing. Furthermore, an outer contour of the sound generator housing has a connecting surface configured to be attached to a motor vehicle structure. The connecting surface is set off from a remaining surface of the outer contour.

A door system for a doorway to a gas-tight chamber includes a door panel that selectively moves between a closed position for sealing a doorway of a chamber and an open position for permitting access to an interior of the chamber through the doorway. The door panel has an inner side generally facing the interior of the chamber when the door panel is in the closed position. A door panel track is connected to the inner side of the door panel. The door panel track selectively cooperates with an interior track of the chamber to facilitate movement of a cart between the door panel to the interior of the chamber.

An integrated catalyst reformer is described, including a housing which surrounds and defines at least two individualized and adjacent chambers. The first chamber is intended for the catalytic conversion of exhaust gases from the MCI and at least one second chamber intended for reforming fuel, ethanol or others, and the heat generated in the first chamber is transferred to the second chamber by thermal conduction. The first chamber is connected, upstream, to the exhaust manifold of the MCI from the inlet nozzle and is connected to the exhaust of the vehicle from the outlet nozzle, while the plenum of the first chamber is filled with a catalytic mesh. The second chamber includes a plenum filled with a catalytic mesh; an intake nozzle intended to receive both ambient air and the fuel to be reformed; and an exhaust nozzle, connected upstream of the intake manifold, so as to allow the reformed fuel to be aspirated.

A fluid sensor protection assembly for protecting a fluid sensor comprises a housing receiving the fluid sensor. The housing includes a bottom wall having a lower inner flow-through opening, a top wall spaced apart from the bottom wall in a vertical direction and having an upper inner flow-through opening, a lower cover member covering the lower inner flow-through opening on an outside of the housing, and an upper cover member covering the upper inner flow-through opening on the outside of the housing. The lower cover member is spaced apart from the lower inner flow-through opening in the vertical direction and forms a lower outer flow-through opening. The upper cover member is spaced apart from the upper inner flow-through opening in the vertical direction and forms an upper outer flow-through opening. A continuous flow-through passage through the housing extends between the lower outer flow-through opening and the upper outer flow-through opening.

An exhaust gas aftertreatment system with an exhaust gas inlet, at least two exhaust gas aftertreatment elements, and a flow chamber. The exhaust gas inlet, the at least two exhaust gas aftertreatment elements, and the flow chamber are arranged relative to one another and fluidically connected together such that exhaust gas flowing through the exhaust gas inlet into the flow chamber can be distributed to the at least two exhaust gas aftertreatment elements. The exhaust gas passes through at least one first of the at least two exhaust gas aftertreatment elements along a first flow direction, and the exhaust gas passes through at least one second of the at least two exhaust gas aftertreatment elements along a second flow direction, wherein the first flow direction and the second flow direction are oriented at least diagonally to each other, preferably anti-parallel to each other.

An exhaust gas treatment device, especially for an exhaust system of an internal combustion engine of a vehicle, includes a housing (12) elongated in a direction of a housing longitudinal axis (L). An exhaust gas treatment unit (18) is arranged in the housing (12). At least one first exhaust gas guiding device (24) is in flow connection with an axially open axial end area (16) of the housing (12). The first exhaust gas guiding device (24) provides a first flow path area (38) extending along an outer side (22) of the housing (12) as well as a second flow path area (47) connecting the first flow path area (38) with the axially open axial end area (16) of the housing (12).

Disclosed is a high-pressure energy storage thermal energy power machine. A gasifier is arranged on an exhaust duct on a cylinder head of an internal combustion engine. The gasifier is provided with gasifying plates in the direction of parallel air flow. Gas holes are arranged on the gasifying plates. The bottom portion of the gasifier is provided with a working medium inlet. Gasifying plates are distributed with gaps. Gas holes are distributed in an array on the gasifying plates. An energy storage chamber is arranged on the cylinder head. The gasifier is connected to the energy storage chamber. The energy storage chamber is connected to a high-pressure valve. The high-pressure valve is arranged on the cylinder head and above the cylinder block. The ratio of the volume of the energy storage chamber to the volume of the cylinder of the internal combustion engine is 1:1-3.
