METHOD OF INITATION IGNITION, INTENSIFYING COMBUSTION OR REFORMING OF FUEL-AIR AND FUEL-OXYGEN MIXES Russian patent published in 2008 - IPC F02M27/04 F02P9/00 

FIELD: engines and pumps.

SUBSTANCE: invention relates to machine building, particularly to power engineering and motor industry, and is designed to intensify chemical processes in working mixtures using a pulse-intermittent nanosecond high-voltage discharge in whatever internal combustion engines including (but no limiting) afterburners, detonation engine combustion chambers, jet engines and gas turbine engines, burners and reformers. The method of initiating ignition, intensifying combustion or reforming of fuel-air and fuel-oxygen (working) mixtures consists in the working mixture is excited in the combustion chamber by a pulsed-intermittent nanosecond high-voltage discharge, the discharge amplitude U[kV] is constrained by the following expression , i.e. 3·10^-17>U/(L×n)>3·10^-18, the high-voltage pulse front edge increase τ_f[ns] is constrained by the following condition, i.e. RC<τ_f<3·10^-18×L²×n/U, while the high-voltage pulse duration τ_pulse[ns] is constrained by the following expression, i.e. 10¹⁷/n<τ_pulse<3·10³¹×(L×R)/(n×n) where U is the high-voltage pulse amplitude, [kV], L is a standard size of the discharge section, [cm], n is the molecules concentration in the discharge section unit space, [cm^-3]. R is the supply line resistance [ohm], C is the capacity of spark gap [F].

EFFECT: lower mix ignition temperature, higher intensity of chemical reactions in combustion and reforming, higher engine efficiency and lower atmospheric emissions.
