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).

A exhaust gas purifier includes a case having a flat transverse section including a pair of facing short sides and a pair of facing long sides, and configured to house a catalytic converter, and an inlet cone including a conical portion, and configured to connect an outlet of the turbine to an inlet of the case. The conical portion includes an inclined wall inclined from a mainstream of the exhaust gas to increase the transverse section of a path of the exhaust gas. A recess recessed inward is formed in a portion corresponding to each of the long sides of the inclined wall of the conical portion.

A mix box for an exhaust system of an internal combustion engine, the mix box being used to incorporate additives into an exhaust gas flow and including at least one inlet tube, at least one outlet tube and a housing for accommodating the inlet tube and the outlet tube, wherein: the housing delimits a volume of the mix box in relation to the surroundings; the inlet tube has an inflow section located inside the housing, which inflow section is provided with at least one inflow opening for introducing the exhaust gas into the housing; the outlet tube has a metering device designed as an injection nozzle at the end of the outlet tube and has an outflow section located inside the housing, which outflow section has a length (La) and is provided with at least one outflow opening for discharging the exhaust gas from the housing; a flow zone is provided between the inlet tube and the outlet tube and the flow zone, over at least 30% of its length (La), is free of flow guiding elements which deflect the flow in a circumferential direction and which have an outer face and an inner face inside the volume.

An exhaust gas system for an internal combustion engine includes a first exhaust gas line leading into a first muffler; a second exhaust gas line arranged fluidly parallel to the first exhaust gas line and leading into a second muffler, wherein the first and second exhaust gas lines are respectively connected upstream of the first and second muffler at a branch to a common exhaust gas feed line; a control valve arranged in the first exhaust gas line upstream of the first muffler; and a damping device fluidly arranged between the branch and the control valve and adapted for damping exhaust gas resonance vibrations.

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.

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.
