Abstract: The paper presents results of experimental, computational and analytical study of the effect of nonequilibrium chemical activation of air-fuel mixture on effectiveness of Diesel process. The generation of a high-voltage multi-streamer discharge in combustion chamber at the compression phase is considered as the method of the activation. The description of electrical discharge system, results of measurement and visualization are presented. The plasma-chemical kinetics of nonequilibrium ignition is analyzed to establish a passway for a proper reduction of chemical kinetics scheme. The results of numerical simulation of gas dynamic processes at presence of plasma-assisted combustion in a geometrical configuration close to the experimental one are described.

Keywords: combustion, internal combustion engine, streamer discharge, chemical kinetics, computational fluid dynamics, numerical simulation.
