Abstract
A method and device for operating an internal combustion engine including a first air duct supplying air to a cylinder of the internal combustion engine, and a second air duct supplying air to a heater for heating an exhaust system. The first and the second air duct each have at least one control element for controlling the amount of air flowing through. The first and the second air ducts are connected by a third air duct to an air filter for providing filtered ambient air to the internal combustion engine. A mass flow sensor is arranged in the third air duct for measuring an amount of air flowing through the third air duct. The measured signal of the mass flow sensor is used to regulate the amount of air flowing through the first and second air ducts as a function of operating states of the internal combustion engine.
