Patent ID: 8239117

Claim:
A device for operating an internal combustion engine comprising at least one cylinder (Z 1 -Z 4 ) with a combustion chamber, an injection valve ( 18 ) that is provided for metering fuel, a lambda controller being provided, the device being designed to adapt a start quantity adaptation value (ST_AD) as a function of a variable that is characteristic of a rotational speed profile during the start (ST) of the internal combustion engine, to adapt a lambda adaptation value (LAM_AD) as a function of at least one control parameter (LAM_RP) of the lambda controller if a preset condition (COND) is met, which presupposes the existence of a quasi-stationary operating state, to adapt an intermediate correction value (ZW_KOR) as a function of a change of the start quantity adaptation value (ST_AD) since a last adaptation of the lambda adaptation value (LAM_AD), to determine a fuel mass (MFF) to be metered as a function of at least one operating variable (BG) of the internal combustion engine, to correct the fuel mass (MFF) to be metered during the start (ST) of the internal combustion engine by means of the start quantity adaptation value (ST_AD), to correct the fuel mass (MFF) to be metered outside of the start (ST) of the internal combustion engine as a function of the lambda adaptation value (LAM_AD) and to correct the fuel mass (MFF) to be metered as a function of the intermediate correction value (ZW_KOR) until for the first time after the respective start (ST) the lambda adaptation value (LAM_AD) is adapted.
