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

摘要

The invention relates to power engineering and engine manufacture and can be used for intensifying chemical processes in a combustion mixture by means of a pulsed high-voltage discharge of nanosecond duration in any type of internal combustion engine. In order to reduce the ignition temperature of combustion mixtures, increase intensity of chemical reactions in combustion and reforming processes and to substantially decrease the release of pollutants to the atmosphere, the inventive method consists in stimulating the combustion mixture in a combustion chamber by means a pulsed high-voltage discharge of nanosecond duration, wherein the discharge amplitude is set up according to a condition of maximising a heat input in electronic degrees of freedom and in a gas dissociation and preventing the passage of plasma electrons to an escape mode at a main discharge stage, the high-voltage pulse leading edge build-up time is limited by the condition of obtaining a homogeneous filling of a discharge gap by plasma and a pulsed energy efficient transmission to the plasma, a high-voltage pulse time is limited by the condition, wherein a highly-unstable plasma state is attained, the discharge gap resistance is reduced, the discharge gap is better matched to a generator, and an efficient electric power input into the plasma is obtained.
