Method and Control Device for Metering Fuel To Combustion Chambers of an Internal Combustion Engine

A method for metering fuel into a combustion chamber of an internal combustion engine, the method comprising:

• metering a fuel quantity to be metered for a combustion by a preinjection and at least one additional partial injection;
• ascertaining, in operation of the internal combustion engine, quantity errors of the preinjection from a signal of at least one sensor;
• forming a correction value as a function of the quantity error of the preinjection;
• and
• correcting the at least one additional partial injection using the correction value.

A control device of an injection system of an internal combustion engine having at least one injector, comprising:

• a metering arrangement to meter a fuel quantity to be metered for a combustion by a preinjection and at least one additional partial injection;
• an ascertaining arrangement to ascertain, in operation of the internal combustion engine, quantity errors of the preinjection from a signal of at least one sensor;
• and
• a correction arrangement to form a correction value as a function of the quantity error of the preinjection, and to correct the at least one additional partial injection using the correction value.
