ABSTRACT:
The invention relates to an ignition system for an internal combustion engine (ICE) that provides fast transfer from a laminar combustion in an ignition kernel to a self-sustaining turbulent flame propagation, thus leading to a reduction in the total time of combustion. The effect is achieved by transiently attacking the ignition kernel with a high-frequency (HF) electromagnetic radiation pulse, which is quasiperiodically modulated with 10-1000 kHz frequency in the initial period of combustion (50-500 .mu.s) following the ignition. Radiation is absorbed by electrons existing only inside the ignition kernel during the initial stage of its development. Due to thermal inertia, the medium perceives the oscillations on the frequency of modulation, whereby the surface of the kernel is developed and is split into separate fractions. This causes transfer from laminar to turbulent bulk combustion. The technique proposed is of an especially great importance for a lean-burn ICE which is normally characterized by low combustion temperature and hindered transition to turbulent flame propagation.
