Abstract
In an internal combustion engine with an exhaust gas turbocharger having an exhaust gas turbine arranged in an engine exhaust pipe upstream of a catalytic converter and a bypass line branching off the exhaust pipe upstream of the exhaust gas turbine and rejoining the exhaust pipe between the exhaust gas turbine and the catalytic converter, a bypass valve is provided which is so controlled that, after startup of the internal combustion engine, the bypass valve is, during a catalytic converter heat-up period, at least partially opened when the internal combustion engine load is below a predetermined value and is only closed when the engine load is above the predetermined value.
