Power-Neutral Exhaust Gas Temperature Reduction Using an Exhaust Gas Turbine Bypass

A method for controlling an internal combustion engine having an exhaust gas turbocharger and an exhaust gas aftertreatment device, includes determining a catalytic converter temperature, comparing the determined catalytic converter temperature with an upper temperature threshold, and, if the comparison determines that the threshold has been exceeded, reducing a proportion of the exhaust gases of the internal combustion engine which are guided through a turbine bypass of the exhaust gas turbocharger.
