Abstract

The system is mounted in the engine compartment of a vehicle, boat, aircraft or locomotive and comprises pressurised containers of (a) water and (b) a fire retarding and extinguishing material such as carbon dioxide powder. Delivery may be by jet spray nozzles. The system may be activated by a smoke detector or impact sensor and a fuel cut off switch can be included. If hit directly, the pressurised containers can rupture so that they release their content into the engine compartment.

Description

2362099 AUTONUTIC MOTOR FIRE EXTINGUISHER This invention relates to
automatic fire extinguishing system for motor vehicle, locomotives, aircraft, water vessels and other fuel run equipments.
Almost all fires involving fuel run vehicles and equipments originates from the engine compartment. This is the best place from where to tackle it.
Thousands of people are killed, crippled or injured and properties worth millions of pounds destroyed needlessly around the world each year from fire resulting from motor accidents. The main source of these fires is mostly as a result of impact of head-on collision of vehicles or trains with other mobile, stationary vehicles such as in cases of motorway pileup or with stationary objects eg. trees and roadside furnitures; or derailment in the case of locomotives and trains. Fire also result from mechanical or electric faults or/and malfunctions.
It is evident that in most cases, even after surviving the initial direct impact, victims are often trapped in the wreckage and consequently left venerable and helpless to the resultant fire.
The collision impact often leaves bust fuel pipes spilling fuel on hot engine and hot exhaust manifold producing highly flammable fumes. These fumes can easily be ignited by sparks from the sparks distributor; sparks from electrical short circuit, or by very hot exhaust pipe.
If flre is not deterred within the first few seconds of impact or malfunction, it spreads fast and soon travels by the fuel pipes, bodywork paint or/and other caustic materials to the usually pressurised fuel tank, which explodes soon after to an impossible flame.
It is apparent that any effort to prevent the potential danger of motor fire must be concentrated on the first few seconds of collision impact or other malfunction, as only merger effort and resources are required to put it off or deter it from spreading to a dangerous proportion if it is tackled at the exact time of happening.
2 Evidently, fatality from road, rail, and even air transport accidents would be reduced immensely if the rate factor is reduced and if possible eliminated altogether. To achieve this objective, time and timing is everything.
The object of this invention is to eliminate and diminish the possibility of motor fire resulting from collision impact or mechanical faults and other malfunctions at the earliest possible stage.
The system provides the much needed and crucial time and opportunity for the surviving driver and occupants of an accident vehicle to escape further injury or death from potential fire; at least until rescue team and professional firefighters arrive. This system would especially be of help in the event of motorway pileup where one fire could trigger a chain reaction with a devastating destruction. This is aimed to add to other exiting measures already in force.
In any event of motor engine fire, the first sign of it is usually smoke. This smoke could either come from:- fumes emission from fuel spillage oVer hot engine and hot exhaust manifold coining from fuel pipe bust; burning wires resulting from electrical short circuit; explosion on impact. The smoke and fuel fumes are used, via a smoke detector, to work as part of the triggering agent of the system's switching device. Simultaneously, electronic impact sensors are also used to complete the sequence to trigger the system's switching device to work.
According to the present invention, there is provided:- 0 Two pressurised cylindrical vessels, one containing fire retarding compound e.g. foam forming chemical or carbon dioxide powder or any other suitable fire extinguishing compound; and the other containing water laced with necessary chemical additive to reduce its surface tension; are mounted on a suitable position within the engine compartment 3 Dispensing units, each fitted with appropriate number and type of high pressure jet spray nozzles are mounted on a suitable area above the engine brock.
Pressure and fire resistant pipes are connect between the pressurized containers and the dispensing units.
Suitable release valves are fitted on the pipes between the pressurized containers and the dispensing units.
A smoke and fumes detecting device of a known type and of suitable sensitivity is fitted within the engine compartment.
Electronically controlled switching units are fitted on each valve and then connected via an integrated circuit to smoke and fumes emission detector. Electronically controlled impact sensors of a determined extent are fitted around and within the engine compartment with necessary wiring circuit extended to the switching units of the valves.
The circuit is also extended accordingly to a fuel cut-off switch, which is coupled with fuel pump to reverse the fuel from the engine back to the fuel tank. Another cut-off switch can he provided to cut off battery power to the sparks distributor in case of a petrol engine.
Specific details of a typical construction of the invention will now be described here below by way of example with reference to the accompanying drawing whereas:- As shown in figure 1; after an accident; when smoke and fumes exceeds a certain and determined intensity, it activate the system into a series of simultaneous reactions as follows:- Smoke and fumes detector W is activated to complete an electric circuit to the system's switching unit 'i'.
4 The electronic switching unit 'i' activates the valves 'c' to open thus forcing the pressurised vessels 'a' and 'h' into spurting rapid and forceful splashing of fire retarding and extinguishing compound eg. foam forming chemical or carbon dioxide powder and water through respective jet spray nozzles 'h' of the dispenser unit 'c' to all over the engine area. Air compressor W; maintains the pressure within the pressurized vessels 'a' and 'h' It comes on every time there is variation in pressure especially when the valves open in case of fire. Non return valves 'p' maintains the one way flow of air pressure within the system.
Simultaneously, an electronic impact sensor 'g' supplements the smoke detector 'g' if the impact exceeds a certain and determined extent.
The switching unit 'i' also activates fuel pump to reverse action thus drawing the remnant fuel from the engine and back in to the fuel tank.
Power supply to the sparks distributor, in case of a petrol run vehicle, is also cut off thus stopping the engine to run.
A warning pilot light 'm' shows on the dashboard.
A warning alarm 'm' sounds within the car cabin area.
An over-ride button 1' fitted on the dashboard is provided to operate the system manually.
The electronic switching unit can he integrated fully or partially with a computerised console to control the system's switching unit's responses to various situations digitally.
If the collision impact is more intense such that the pressurized vessels suffer a direct hit, they are designed to rupture pouring their contents all over the engine compartment thus retarding or putting off any resulting fire.
