  • Method for the exhaust aftertreatment of an internal combustion engine and exhaust aftertreatment system
    Patent number: 10934912
    Abstract: The invention relates to a method for the exhaust aftertreatment of an internal combustion engine, which on the outlet side is connected to an exhaust gas system. Provided in the exhaust gas system is at least one exhaust aftertreatment component with which, upon reaching the light-off temperature of this exhaust aftertreatment component, the gaseous limited exhaust gas components may be converted into unlimited exhaust gas components. An introduction point is provided at an exhaust duct of the exhaust gas system, at which a hot gas, in particular an exhaust gas of an exhaust gas burner, is introduced into the exhaust duct. The hot gas mixes with the exhaust gas of the internal combustion engine in such a way that a hot mixed gas results in which the unburned exhaust gas components are oxidized to unlimited exhaust gas components, without a catalytically active surface.
