Abstract
An engine fire suppression system comprising a canister charged with a fire suppressant material, a piping system connected to the canister and terminating in a U-shaped manifold having a plurality of discharge orifices, a redundant parallel valve system in connection between the canister and the manifold, and a fire detection system controlling the redundant parallel valves having a heat sensing circuit and a smoke sensing circuit. A back up power supply is provided that is constantly maintained at full charge by the vehicle alternator but that has sufficient electrical power to power the system in the event the vehicle battery is removed. In addition, an audible alarm is initiated for several seconds prior to discharging the canister contents and during the discharge of the canister contents to alert vehicle passengers that the canister contents will be discharged or are being discharged.
