摘要:
In a device for cleaning vehicular exhaust gas, in particular a diesel exhaust particle filter, the individual bodies which together constitute a one-piece filter body, are arranged so as to have an oblique angle with an axis of symmetry of the filter body and/or with the horizontal plane, here in relation to the installation condition of the device in the vehicle and/or an underside of the filter body having a reduced curvature compared to portions of the outer contour adjoining the underside.

A method of regenerating an exhaust gas purification filter, in particular for internal combustion engines, uses a vaporized liquid that is to be introduced into the exhaust gas flow. A surface temperature of a heating element in a vaporizer chamber is limited to a maximum of 700 to 750° C.

A device for exhaust gas heat utilization in internal combustion engines of motor vehicles includes an exhaust gas line which in sections includes a first exhaust gas flow duct and a second exhaust gas flow duct connected in parallel. A valve flap is movable between a closed position and an open position, which can selectively close or at least partly clear a flow cross-section of the first or second exhaust gas flow duct. At least one thermoelectric generator module is thermally coupled with the second exhaust gas flow duct and with a cooling circuit. The device also includes an expansion material actuator for temperature-dependent actuation of the valve flap.

An injection nozzle is used in particular for introducing an oxidizable fluid into an exhaust system upstream of a catalyst or filter. The injection nozzle includes a heating element and a heat accumulator, which can be heated up by the heating element and can dissipate stored heat to the oxidizable fluid. A method for introducing an oxidizable fluid into an exhaust system upstream of a catalyst or filter utilizes the injection nozzle that includes the heating element and a heat accumulator. The heating element is switched on before an injection process, so that the heat accumulator is heated up, and the oxidizable fluid only is injected later, so that the heat accumulator can release energy to the oxidizable fluid and can evaporate the same.

An apparatus comprises an emissions trap and a transfer function device. The transfer function device is configured to determine a transfer function of the emissions trap wherein the transfer function is representative of loading of the emissions trap. An associated method is disclosed.
摘要:
An apparatus comprises parallel and coaxial first and second exhaust gas passageways, a fuel reformer positioned in the first exhaust gas passageway to generate partial combustion product (e.g., H2 and/or CO), and a component such as an emission abatement device or an internal combustion engine positioned to receive the partial combustion product from the first exhaust gas passageway and exhaust gas from the second exhaust gas passageway. An associated method is disclosed.
摘要:
An apparatus comprises an exhaust system and an injection system. The injection system is configured to vaporize a first liquid portion of an agent into at least one bubble so as to inject a second liquid portion of the agent into the exhaust system by use of the at least one bubble for delivery of the agent to an emission abatement device of the exhaust system. An associated method is disclosed.
摘要:
An apparatus comprises an emissions trap and a loading determination device. The emissions trap is configured to trap emissions present in exhaust gas and comprises a first local region and a second local region. The loading determination device is configured to determine emissions loading of the first local region and emissions loading of the second local region. An associated method is disclosed.
摘要:
A thermoelectric module (10) has a plurality of series-connected thermoelectric elements which are arranged between a first module housing plate defining a high-temperature side and a second module housing plate defining a low-temperature side, wherein laterally beside the thermoelectric elements and towards the end faces of the module housing plates at least one elastic compensating element is provided, which exerts a lateral holding force on the thermoelectric elements and extends from one inner side of the opposed module housing plates to the other. Such thermoelectric module (10) is contained in a thermoelectric generator unit (100), with a generator housing (102) in which at least one elastic compensating element (20) and at least one thermoelectric module (10) are accommodated, wherein the generator housing (102) exerts a pretension on the thermoelectric module (10) via the elastic compensating element (20).
