Abstract: A method for the load-dependent opening and closing of a blow-off valve flap of an internal combustion engine with a turbocharger is provided, in which by at least one detector on an internal combustion engine inlet side, at least one air pressure value, one air mass flow value and/or an opening position of a valve of the suction pipe are detected and transmitted to a control device. By the control device from the received values a current load of the internal combustion engine is determined, and by the control device based on the determined current load of the internal combustion engine and/or of the turbocharger, control inputs for an actuator of the blow-off valve flap are generated and transmitted to the actuator. The blow-off valve flap is completely opened, partially opened, minimally opened or closed and held in the respective position by the actuator dependent on the current load.
