Abstract

See full text

A method for operating an exhaust burner, which is situated in an exhaust system downstream from an internal combustion engine of a motor vehicle. Prior to and during a start phase of the exhaust burner, an air-mass flow supplied to a combustion chamber of the exhaust burner is increased, in particular in a strictly monotonical manner, between a start time in a starting air-mass flow and a further time in a further air-mass flow. Prior to the further time, fuel is supplied to the combustion chamber. A fuel-air mixture is produced in the combustion chamber from the fuel and air of the air-mass flow. The fuel-air mixture is ignited with the aid of an ignition device which is continuously hot or forms ignition sparks intermittently.
