INVENTION DES CRIPTION Field of the invention
The invention belongs to the field of motor vehicle engine fire- extinguisher systems .
Technical problem
It is often noted that when fire breaks out in the motor vehicle engine, it is very difficult to extinguish it adequately due to the poor access to the source of the fire. The size of the standard fire-extinguishing equipment makes it almost impossible to fit in the fire-fighting systems which use such equipment, not to mention the extinguishants they use are usually not able to extinguish fire in the motor vehicle engine, either due to its limitations with regards to a particular fire class, or due to their chemical products which have a detrimental effect on the engine.
Current technologies
There are few similar systems, which are, however, too cumbrous to be fitted in the vehicle and/or are not able to extinguish fire safely and satisfactorily.
S ummary of the invention
The primary aim of this invention is to make it possible to adequately extinguish fire in the motor car engine with no harmful consequences for either the engine, man or the environment, resulting from the extinguishing process or the extinguishant.
The automatic motor vehicle engine fire-extinguisher system hereby outlined consists of a fire-extinguisher, such as the patented «Mangiafuoco® - 8B» flame inhibitor, composed of potassium salts, which extinguishes fire by the combustion of oxidizing agents oxidants and additives, activated by the friction igniter, as well as by the creation of gaseous products and powder j et, which extinguishes fire

Detailed description of the invention
Automatic motor vehicle engine fire-extinguisher system consists of:
1 . Flame inhibitor
2. Lid
3. Electric igniter
4. Electronic device which measures the temperature and activates the electric igniter
5. Temperature sensors
6. Manual activator
7. Electric switch
8. Battery
9. The protected motor vehicle battery
1 0. Friction igniter
1 1 . Flame inhibitor mixture Electric igniter (3) cap is situated on the surface of the friction igniter ( 1 0) of the flame inhibitor ( 1 ) or in the flame inhibitor mixture (1 1 ), depending on the type of its composition. The lid (2) is positioned on the activation spot of the flame inhibitor ( 1 ), that is, on the electric igniter (3) cap , so as to fixate it, and at the same time devised so as to make the flow of gaseous products smooth and unobstructed upon the activation of the flame inhibitor, or, in other words, to have an axial bore sufficiently wide to make this process run smooth. The other end of the electric igniter (3) is electrically connected to the electronic device which measures the temperature and activates the electric igniter (4) . Temperature sensors (5) are electrically connected to the electronic device (4) and are used to measure the temperature of a given environment and subsequently convey temperature data to the electronic device (4) , which at a set temperature activates the electric igniter (3 ), and the electric igniter in its turn activates the flame inhibitor ( 1 ) . Protected motor vehicle battery (9) is electrically connected to the electronic device (4) and supplies it with electric power and, consequently, makes automatic functioning, that is, temperature measurement and the electric igniter (3 ) activation, possible. The manual activator (6) is electrically connected to the electronic device (4) and is compo sed of the electric switch (7) and the battery (8) which are electrically interconnected together to the electronic device (4) . The manual activator (6) enables the driver to manually activate the electric igniter (3 ), that is, the flame inhibitor ( 1 ), by means of the electric switch (7) and the battery (8), which serves as a secondary source of electric supply required to activate the electric igniter (3) .
The application of the invention
The automatic motor vehicle engine fire-extinguisher system is designed to control the temperature in the motor vehicle engine automatically. Temperature sensors are fitted on the inside surface of the hood simmetrically so as to cover a larger or desired area. The electronic device is installed out of the bounds of the protected area and is electrically connected to the source of electric power supply of the protected motor vehicle, the temperature sensors and the manual activator, which is placed within the driver's reach. When the temperature in the engine hits the dangerous or set numbers, either as a consequence of overheating or fire, the temperature sensors convey the message of the occurence to the electronic device, which then activates the electric igniter, which in its turn activates the flame inhibitor placed within the protected area. At any time for any reason whatsoever, by means of the manual activator the driver can activate the flame inhibitor and start the fire-extinguishing process . This would not be possible without the electric switch and the battery, which serves as a secondary and independent source of electric power supply of the electric igniter, as an additional safeguard.
