Abstract: An exhaust emission control device has at least one exhaust gas line, at least one particulate filter and/or at least one exhaust gas catalytic converter connected to the exhaust gas line, and a heated catalyst assembly arranged upstream of the particulate filter and/or the exhaust gas catalytic converter. The heated catalyst assembly is designed to react fuel with exhaust gas, and has a housing provided with an inlet and an outlet connected to the exhaust gas line such that a partial flow of the exhaust gas flowing in the exhaust gas line can be fed through the inlet into the housing and can be discharged from the housing through the outlet back into the exhaust gas line downstream of the inlet. An exhaust emission control device of this type may be used in conjunction with an internal combustion engine, and may be used for emission control of exhaust gas.

Abstract: A turbocharger has compressor arrangement configured to compress the fresh air of an internal combustion engine. The turbocharger has at least one compressor housing (with a fresh air inlet) and a fresh air outlet. At least one compressor impeller is arranged in the compressor housing, and with at least one exhaust gas turbine for driving the compressor arrangement, with at least one turbine housing with an exhaust gas inlet and an exhaust gas outlet. At least one turbine wheel is arranged in the turbine housing. A heated catalytic converter is configured to at least partially convert supplied fuel with fresh air and/or exhaust gas. The heated catalytic converter includes a catalytic converter housing with a gas inlet and a gas outlet and a fuel inlet. The catalytic converter housing and the compressor housing and/or the turbine housing are in thermal contact on at least one part surface.

Abstract: A method for introducing heat into at least one component of an exhaust-gas aftertreatment device of an internal combustion engine (15). The method involves at least partially reacting a partial flow of an exhaust-gas flow with fuel in a heated catalyst (2) and then feeding back the resulting product to the exhaust-gas flow, The amount of fuel fed to the heated catalyst and/or the partial flow fed to the heated catalyst is controlled, by open-loop or closed-loop control, in accordance with the exhaust-gas temperature upstream and/or downstream of the component. The amount of fuel fed to the heated catalyst and/or the partial flow fed to the heated catalyst is determined by means of at least one heated-catalyst characteristic map. A computer readable medium stores a signal sequence representing data suitable for transmission by means of a computer network, to an open-loop or closed-loop control device to carry out the above-described method.

Abstract: The ignition characteristics of a fuel are adjusted using a unit which has a distribution zone, a oxidation zone and a conversion zone. Fuel is distributed in the distribution zone having a distribution structure. A portion of the fuel is oxidised in the oxidation zone with a oxidising agent on a catalyst on a catalyst carrier, and a portion of the distributed fuel and/or of another supplied fuel is thermally and/or catalytically converted in the conversion zone. The ignition characteristics of the fuel are adjusted via: the molar ratio of oxygen included in the oxidising agent to the oxygen required for the complete oxidation of the fuel provided; and/or via the pressure in the unit; and/or the dwell time; and/or the temperature. Exhaust emissions, in particular NOx and soot emissions, can be lowered.

Abstract: A method is described for operating a catalytic evaporator (1), with the step: feeding fuel and an oxidant to the catalytic evaporator, which method is distinguished by the fact that (a) the feed of the fuel is performed as a pulsed feed, and/or (b) the feed of the oxidant is performed as a pulsed feed.
