Abstract (en)
[origin: WO2010057788A1] According to a current operating state (BZ) of an internal combustion engine and/or a specified particle number emission limit (PE), a minimum hydrocarbon concentration (HCMK) of a combustion chamber exhaust gas of the internal combustion engine that is required to comply with the specified particle number emission limit is determined. An operation (B) of the internal combustion engine is specified to achieve a hydrocarbon concentration (HCK) of the combustion chamber exhaust gas that is at least as large as the determined minimum hydrocarbon concentration (HCMK).
