Abstract

The invention relates to an HPDF operation method for an internal combustion engine (100) with internal formation of a mixture and self-ignition, in which, (i) for a combustion cycle of an operation cycle under high pressure, as main fuel (63) at a first time point, the introduction of a nonself-igniting or gasoline engine fuel, and as ignition fuel (64) at a second time point, the introduction of a self-igniting or diesel fuel into a combustion chamber (20) of the internal combustion engine (1) are at least initiated and/or performed, (ii) a self-ignition of the ignition fuel (64) and with the self-ignition a nonself-ignition of the main fuel (63) are effected, and (iii) the self-ignition of the ignition fuel (64) is performed temporally and/or spatially in such a way that the main fuel (63) is ignited at a location (1) and/or in a region of an jet tip (630 and/or a propagation front (630 of a quantity of introduced main fuel (63)—in particular temporally firstly.
