Abstract
A method and an arrangement serve to operate an internal combustion engine equipped with an exhaust-gas turbocharger. An after-injection takes place with the overlapment of the opening angle of the inlet and outlet valves of a cylinder. The after-injection leads to an air/fuel mixture in the exhaust-gas system which is combustible. This mixture is combusted by driving an additional ignition device in the exhaust-gas system.
