Abstract
An exhaust system purifies a gas flow of harmful substances. The exhaust system contains at least device for supplying a reducing agent, a first catalytic converter, and a particle trap, in the direction of flow of the gas flow through the exhaust system. At least one other exhaust purification component is provided and/or there is a distance of at least 0.5 meters between the first catalytic converter and the particle trap. In addition, a mixer and a second catalytic converter are positioned directly upstream of the particle trap. A regeneration of the particle trap disposed in the exhaust system is carried out. A reducing agent is introduced into the exhaust gas system, only upstream of the turbocharger, for carrying out the regeneration process of the particle trap.
