FIELD: fire-fighting systems of tanks, infantry combat vehicles and self-propelled guns. SUBSTANCE: in addition to the known fire-fighting system acting without stopping the engine, the claimed system includes additional subsystem of lead automatic supply for a preset short period of time, a portion of exhaust gases from engine exhaust manifold to free space of motor-fuel compartment and sealing of the latter after armor penetration and operation of motor-fuel compartment armor penetration transducer; additional subsystem of lead supply of a small part of filtered exhaust gases from engine exhaust manifold to free space of sealed motor-fuel compartment for a prolonged time in the region of combat action; additional subsystem for supply by suction of outboard air to face masks of crew members for the time of fire fighting in crew compartment after switching out of ventilation. EFFECT: prevented occurrence of fire or explosion of fuel vapors in motor-fuel compartment in case of armor penetration due to lead creation of stagnant gas media lean in oxygen. 4 cl, 1 dwg
