Abstract
An air supply to an internal combustion engine, which includes at least one cylinder and a heater. A first air duct is provided for supplying air to the at least one cylinder of the internal combustion engine for operating the internal combustion engine and a second air duct is provided for supplying air to a heater for heating an exhaust system of the internal combustion engine. The first and second air ducts are connected by a third air duct to an air filter, for providing filtered ambient air to the internal combustion engine. The first and second air ducts in each case have at least one control element for controlling the amount of air flowing through. The second and third air ducts in each case have a mass flow sensor for measuring a mass of the air flowing through the relevant air duct. Methods and devices for diagnosing the air supply are also described.
