Abstract

An exhaust-gas aftertreatment system, having a catalytic converter and/or particle filter which are/is assigned a burner arranged upstream in an exhaust line, to which burner fuel can be supplied via a fuel nozzle device and also combustion air can be supplied, and wherein the combustion air and the fuel emerging from the fuel nozzle device are mixed in a downstream air swirl vaporizer nozzle. An exhaust-gas aftertreatment system having a burner which operates reliably with a compact design and in which the supplied energy for operating the burner is reduced in relation to known systems. The fuel nozzle device has a nozzle body which extends at least from an inlet to an outlet and which has arranged therein a support body, which nozzle body and support body together produce a film-forming fuel supply duct.
