A method () for diagnosing the functionality of a burner (), comprising: determining a lambda value () of an exhaust gas of the burner (), comparing () the determined lambda value to a time-based changing lambda threshold (), and detecting a malfunction () when the determined lambda value exceeds the time-based changing lambda threshold (). Furthermore, a computing unit and a computer program for carrying out such a method () are proposed.

Method, computing unit, and computer program for diagnosing the functionality of a burner

A method for operating a burner, comprising supplying a controlled quantity of combustion air to the burner, supplying a controlled quantity of fuel to the burner, igniting the air-fuel mixture in the burner, determining a pressure pulsation value in the exhaust gas downstream of the burner and/or in an air path upstream of the burner, and adjusting the quantity of combustion air and/or the fuel depending on the pressure pulsation value. Further proposed are a computing unit and a computer program product for performing such a method.

Method, computing unit, and computer program for operating a burner

A method for operating a fuel-operated burner () downstream of an engine () and upstream of a catalytic converter (), comprising an actuation of an ignition apparatus () of the burner () during a pre-definable preheating phase, without delivering fuel () to the burner () during the preheating phase, and, after the end of the preheating phase, a timely delivery of fuel () to the burner () and combustion of the delivered fuel () in the burner (). Further, a computing unit and a computer program product for carrying out such a method are proposed.
