Abstract
The operation of an internal combustion engine under unfavorable operating conditions can lead to the formation of deposits in the combustion chamber (). A method and an arrangement for operating an internal combustion engine (), especially of a motor vehicle, is suggested, wherein fuel is conducted into a combustion chamber () and is there combusted. When deposits are detected in the combustion chamber (), measures are initiated in a targeted manner for cleansing the combustion chamber (). A knocking combustion is especially introduced and/or a cleansing liquid is added to the inducted combustion air.
