Abstract
The work shows the dependence of the moment of the discharge-activated zone ignition and the moment of self-ignition of the fuel mixture in the region ahead of the combustion wave front on two parameters: the crankshaft rotation angle at which the discharge was initiated and the specific energy input into the streamer channel. It is shown the necessity to take into account the change in pressure in the cylinder due to the movement of the piston in order to more accurately determine the optimal ignition limits of the activated zone and the occurrence of self-ignition. When modeling, the inhomogeneous formation of chemically active particles associated with the streamer and multi-pulse nature of the discharge was taken into account.
期刊介绍：
High Temperature is an international peer reviewed journal that publishes original papers and reviews written by theoretical and experimental researchers. The journal deals with properties and processes in low-temperature plasma; thermophysical properties of substances including pure materials, mixtures and alloys; the properties in the vicinity of the critical point, equations of state; phase equilibrium; heat and mass transfer phenomena, in particular, by forced and free convections; processes of boiling and condensation, radiation, and complex heat transfer; experimental methods and apparatuses; high-temperature facilities for power engineering applications, etc. The journal reflects the current trends in thermophysical research. It presents the results of present-day experimental and theoretical studies in the processes of complex heat transfer, thermal, gas dynamic processes, and processes of heat and mass transfer, as well as the latest advances in the theoretical description of the properties of high-temperature media.
