FIELD: fire safety.
SUBSTANCE: device for automatic local fire protection of the car is made in the form of a capsule, which is fixed in the shell by retaining straps that can be moved together with the capsule when the inert gases released when the gas-generating charge is activated towards the knife. The knife is made, for example, cross-shaped and rigidly fixed on the shell in front of the spray nozzle, the shell of the capsule being more elastic than the straps. The device for automatic local fire protection of the car is carried out in the following way. Destruction of the shell of a capsule with a nanopowder is that the deformation of the shell of the capsule is carried out by separating the inert gases by a slowly burning gas-generating pyrotechnic charge and moving the capsule in its fracture site together with the restraining straps towards the local destruction means until the shell is completely destroyed by the knife.
EFFECT: high fire extinguishing efficiency, by increasing the possibility of inhibiting chemical reactions in the combustion zone.
