Detonation combustion criteria are considered, used at the modelling of the engine operation, engines of external mixture forming and forced ignition. It is shown that the more spread integral criterion of Livenhood and Vou, relating to the two-zone model of the combustion process, allows to predict the fact of the detonation in the cycle, but it can't ensure the desired evaluation of the detonation start moment. At modelling pre-flame reactions are recommended to consider in order to predict better the moment of the detonation start in the cycle.
