FIELD: power engineering; devices for starting installations operating on energy of combusted high energy non-self-igniting fuels. SUBSTANCE: cooling jacket is made in form of channels 13 formed by longitudinal ribs 12 inclined at outlet to longitudinal axis through angle of 37-52 degrees. Central electrode 4 of spark plug 3 is placed in fuel main line 5. Radial projection 10 are made on inner surface of oxidizer collector 7. Oxidizer jet nozzles 11 are installed in these bosses. Nozzles are pointed to electrode 4 of spark plug 3. EFFECT: enhanced reliability of operation. 4 dwg
