Abstract
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.
