Abstract: An automatic engine fire extinguishing system for automatically detecting and extinguishing an engine fire of a vehicle permitting a user to exit the vehicle without having to worry about actuating the fire extinguishing system. The system includes at least one canister that is mountable to the vehicle and positionable adjacent to the engine. The canister has an interior for holding a fire extinguishant under pressure. A valve is mounted on the canister for controlling a flow of the fire extinguishant from the canister. A conduit is coupled to the valve for carrying the fire extinguishant flowing through the valve away from the canister. The conduit has at least one opening for emitting the fire extinguishant from the conduit. At least one fire detector is provided for detecting a fire and opening the valve permitting the fire extinguishant to flow through the conduit exiting the opening and extinguishing a fire.
