Today, a method of automatic fire detection and extinguishing is widely used on vehicles equipped with internal combustion engine and safety pillows. This method provides for automatic detection of a car crash by means of blow sensors and for spraying of a fire-extinguishing agent delivered from a container and regulated by a control valve.

In the newly-patented method, a fire-extinguishing agent is sprayed under a preset program with a help of a processing/controlling unit (PCU) through numerous independently-activated nozzles located in different parts of a vehicle. Carbon dioxide contained in the vehicle container is used both as a cooling agent in a car condition system and as a fire-extinguishing agent in a fire-protection system. A cooling fire-extinguishing nozzle located in a motor compartment is turned on simultaneously with an activation of safety pillows that protect passengers in emergency. Activation of fire-extinguishing nozzles located in a car saloon is delayed by a preset time in relation to a strike time determination. According to the newly-patented method, liquid carbon dioxide is used as a fire-extinguishing agent.

Equipment applied nowadays for automatic fire detection and extinguishing in vehicles includes one or more blow sensors incorporated in a system that detects blows and activates air safety pillows and valves. The valves are connected with a motor compartment and, possibly, car saloon and fuel tank, and control fire-extinguishing agent delivery from the container.

The device, specially developed to implement the new method in practice, additionally includes the CPU incorporated in a system that detects blows and activates air safety pillows. The CPU controls valves connected with a motor compartment and, possibly, car saloon and fuel tank, through a pipe and independently-activated nozzles. The nozzles in accordance with a preset time program spray liquid carbon dioxide, contained in the vehicle container, which is also used as a cooling agent in air condition system. Another modification of the patented device comprises additional container filled up with a mixture of gases and argon; this container is connected with another container filled up with a fire-extinguishing agent. Combination of these two containers allows to obtain appropriate gas compound to extinguish fire in a car saloon.
