Abstract
For the purpose of identification of a combustion chamber producing undesirable hunting in a fuel injection combustion engine, the duration of injection of a defined injection valve is changed in such a manner that additional hunting is caused, and from the crank angle interval (KW) between the additional and the undesirable hunting, is derived, taking into account the rotational speed n of the engine, an identification signal for the combustion chamber to be identified. The identification signal is utilized to change the fuel injection time for the combustion chamber causing the uneveness to eliminate the latter.
