Fire extinguishing system

Fire extinguishing system elements

1 — the Tank with a quencher

2 — System of tubes


The fire extinguishing system joins automatically after operation of its temperature sensor. The quencher from two tanks passes through system of tubes and leaves through openings in it (2 full-line nozzles in a daigatelny compartment and 78 openings under the car).

Fire-resistant cables are brought to temperature sensors (to 1100'C).

The fire extinguishing system remains efficient and at the parking; besides, it can be included manually. The applied quencher is not toxic, and its aerosol does not cause corrosion, leaving only a deposit which can be removed easily with compressed air or a cleaner of the engine.
