A method for introducing heat into at least one component of an exhaust-gas aftertreatment device of an internal combustion engine (). The method involves at least partially reacting a partial flow of an exhaust-gas flow with fuel in a heated catalyst () 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.

Method for introducing heat into at least one component of an exhaust-gas aftertreatment device, software and open-loop or closed-loop control device

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.
