Abstract

An internal combustion engine, eg diesel engine, in which fuel is injected into each cylinder from a fuel rail is operated by determining a first energizing time (ETPil) and a second energizing time (ETMain) for a first (eg pilot) and a second (eg main) fuel injection in the same engine cycle and monitoring the dwell time (DT) between the first and second fuel injections. If the dwell time (DT) is smaller than a predefined critical dwell time (DTcrit) eg the pilot and main injection fuel quantities are hydraulically fused (injection quantity fusion (IQF) mode), the energizing time value (ETMain) of the second injection is corrected (reduced) using a correction factor (KET) which is determined as a function of the fuel quantity values (QMain,QPil) injected in the first and in the second injection, of a fuel rail pressure value (PRail) and of the dwell time (DT) between the first and second fuel injections. The second injection is then performed using the corrected energizing time (ETâ Main). The total quantity injected is thus made equal to the sum of the individual injections in non-IQF mode.
