Abstract
Suggested is a procedure for operating a self-igniting Otto engine (OM) with at least one inlet valve (), with one or several variably controllable outlet valves (), with a sensor () for a continuous detection of an air-fuel-ratio (λ) of the Otto engine (OM) and with a sensor () for detecting an engine speed n of the Otto engine (OM), whereby the fuel is directly injected into at least one combustion chamber () and whereby the Otto engine (OM) is operated in such a way, that a desired combustion focus (MFB) is adjusted. The procedure is thereby characterized, in that the self-igniting moment of the fuel is influenced by an injection moment depending on a combustion focus (MFB). An independent claim relates to a control unit that is customized for controlling the process of the procedure.
