IGNITION AND COMBUSTION METHOD BY MEANS OF PULSED PERIODIC NANOSECOND HIGH-VOLTAGE DISCHARGE

摘要

This invention relates to power engineering industry and engine-building andisdesigned for intensification of chemical processes in the combustible mixtureusing pulsedperiodic nanosecond high-voltage discharge in internal combustion engines ofany kind,including (but not limited to) afterburners, combustors of detonation engines,jet engines andgas turbine engines, in power burners and reformers. For reduction ofcombustible mixturesignition temperature, increase of intensity of chemical reactions incombustion and reformingprocesses and material reduction of release of harmful substances into theatmospherecombustible mixture in the combustion chamber is excited by means of pulsedperiodicnanosecond high-voltage discharge, at that discharge amplitude is set so as toprovidemaximization of the discharge energy deposition in electronic degrees offreedom and gasdissociation and to prevent plasma electrons transfer into the whistler modeat the basicstage of discharge, besides, high-voltage pulse leading edge rise time limitedby theconstraint allowing to attain uniformity of filling the discharge gap withplasma andeffectiveness of pulse energy transfer to plasma, high-voltage pulse durationbeinglimited by the constraint providing attainment of strong non-equilibriumcharacter ofpulse discharge plasma and reduction of the discharge gap resistance, itsbetter interfacewith the generator and effective electric energy deposition into plasma.
