ABSTRACT:
The invention relates to a direct-injection internal combustion engine that is operated in a first operating range associated with the low part load, with largely homogeneous combustion of the mixture and subsequent injection. Said internal combustion engine is operated in a second operating range associated with the middle part load, with low-temperature combustion of the mixture. In this way, minimum nitrogen oxide and soot emissions and a high degree of efficiency can be achieved both in the lower part load region and up to the full load region.
