abstract = "Kinetics of an artificial ignition at injection a certain amount of radicals is analyzed numerically on example of H2:O stoichiometric mixture. Kinetic curves for gas temperature and production of radicals are analyzed and compared for cases of thermal and artificial ignition. Kinetic curve for gas temperature under dissociation similar to one realized in volume nanosecond discharge is given. Possible mechanisms of a shift of the ignition threshold by nonequilibrium plasma are analyzed. Experimental examples of the discharge ignition of H2:O2 mixture diluted with Ar under the kinetic explosive limit (II) are demonstrated. Examples of low-temperature oxidation and high-temperature ignition of different gas mixtures containing hydrocarbons are listed and analyzed. For low-temperature oxidation, we have investigated experimentally kinetics of alkanes (from methane to decane) with oxygen or air at different equivalence ratios, kinetics of C2H 5OH, CH3COCH3, C2H2 in their mixtures with oxygen and CO:O2 mixtures with small controlled additives of water vapor. For high-temperature ignition, a set of stoichiometric mixtures CxH2x+2 : O2 (20\%) diluted by Ar (80\%) for hydrocarbons from CH4 to C4H10 and stoichiometric mixtures CxH2x+2 : O2 (10\%) diluted by Ar (90\%) for hydrocarbons from CH4 to C5H 12 have been analyzed experimentally. Typical energy values are given for all the experiments. Kinetic scheme for low-temperature oxidation is discussed. For a case of a high-temperature ignition, the shift of a temperature threshold in comparison with the autoignition is represented. The kinetic approach to the problem of artificial ignition is discussed on the basis of experiments where the autoignition, ignition by pulsed volume discharge and laser flash-photolysis at 193 nm. Values of the ignition delay in gas mixture O2:H2:N2O:Ar=3:30:10:50 are represented. The kinetic scheme has been proposed to describe autoignition and ignition by a flash-photolysis. The results of a numerical modelling are given.",
