A method for setting a mass flow rate of air to be provided in a charging mode; in the charging mode (where a throttle valve is open), the pressure prevailing in an induction pipe only being set via an adjustable mass flow rate of supplied air; a requested torque corresponding to a mass flow rate of air into a cylinder, the mass flow rate of air into the cylinder being adjustable via the pressure in the induction pipe; to set the mass flow rate of air into the cylinder, the pressure in the induction pipe being adjusted by a control system in accordance with a specifiable dynamic charge response characteristic.
