Abstract:
A method for dividing up a total fuel amount (VG), which is to be injected into a combustion chamber of a cylinder during a combustion cycle (Z1), into a plurality of injections (E1, E2, HE), comprising the following steps:determination of a first fuel amount (VE1), which is to be injected into the combustion chamber of the cylinder during a first injection (E1) of the combustion cycle (Z1); determination of a fourth, minimum fuel amount (VHEmin) for a third injection (HE) of the combustion cycle (Z1); comparison of the total fuel amount (VG) minus the first fuel amount (VE1), to the fourth, minimum fuel amount (VHEmin); setting of the first fuel amount (VE1) and a second fuel amount (VE2), which is to be injected into the combustion chamber of the cylinder during a second injection (VE2) of the combustion cycle (Z1), to zero; setting of a third fuel amount (VHE) for the third injection (HE) to the total fuel amount (VG), when the total fuel amount (VG) minus the first fuel amount (VE1) is greater than or equal to the fourth, minimum fuel amount (VHEmin); and use of the third fuel amount (VHE=VG); the first injection (E1) occurring prior to the second injection (E2), which occurs prior to the third injection (HE).
