The subject of this thesis is the development of a method for the numerical simulation of gasoline self-ignition. In addition to the calculation of non-reacting flows with moving and stationary computational grids, a piloted methane-air jet flame is simulated. In addition, the work gives an outlook on the treatment of a near-production single-cylinder 4-stroke gasoline engine with direct injection in compression-ignition mode. The developed numerical method is based on a time-resolved, three-dimensional description of the gas and the disperse phase using the ALE scheme in the context of the coarse structure simulation. In addition to the coarse structure simulation, the existing solution algorithm Kiva was extended with the transport of passive and reacting scalars. The chemical reactions are described using the FGM or the PV model. The FGM model offers the possibility to map non-premixed flames, whereas the PV model is used to map the self-ignition processes. The results of the investigations support the assumption that the coarse structure simulation has a high potential for predicting internal engine processes.
