摘要： A method for operating an internal combustion engine in a state of controlled self-ignition. The internal combustion engine includes a combustion chamber, at least one intake valve and at least one exhaust valve whose opening times can be changed. A fresh mixture is introduced into the combustion chamber during an intake stroke and an ignitable gas mixture is produced in the combustion chamber by way of the introduction of fuel and compressed in a compression stroke, whereby the gas mixture self-ignites toward the end of the compression stroke.The fresh mixture is introduced into the combustion chamber by way of a compression mechanism during the intake stroke.

摘要： Suggested is a procedure for operating a self-igniting Otto engine (OM) with at least one inlet valve (14), with one or several variably controllable outlet valves (15), with a sensor (21) for a continuous detection of an air-fuel-ratio (λ) of the Otto engine (OM) and with a sensor (22) for detecting an engine speed n of the Otto engine (OM), whereby the fuel is directly injected into at least one combustion chamber (10) and whereby the Otto engine (OM) is operated in such a way, that a desired combustion focus (MFB50%set) 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 (MFB50%set). An independent claim relates to a control unit that is customized for controlling the process of the procedure.
