Abstract:
1. An exhaust gas aftertreatment device for an internal combustion engine, comprising an introduction device comprising a burner, a fuel-and-air supply device, a combustion chamber, an exhaust gas line, an injection device for injecting hydrocarbons into the exhaust gas line, and an outlet, wherein the injection device is configured to inject a quantity of hydrocarbons that is injected separately from any fuel output by the fuel-and-air supply device, the introduction device is configured to at least partially evaporate and chemically modify the hydrocarbons injected from the injection device by at least one of crack reactions and partial oxidation, while suppressing ignition of the injected hydrocarbons, the introduction device is configured for joining to an exhaust pipe carrying a process exhaust gas output from an internal combustion engine for introducing the at least partially evaporated and chemically modified hydrocarbons into the process exhaust gas, and the introduction device is free of a catalytic coating between at least the combustion chamber and the outlet.
