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.
