Abstract
A method for metering fuel into a combustion chamber of an internal combustion engine is provided, in which a fuel quantity to be metered for a combustion is metered by a preinjection and at least one additional injection, and in which, in the operation of the internal combustion engine, quantity errors of the preinjection are ascertained from the signal of at least structure-borne noise sensor. The method is distinguished in that a correction value is formed as a function of the quantity error of the preinjection, and at least one of the additional injections is corrected using the correction value. A control device is also provided that controls the method.
