ABSTRACT:
A fire extinguisher apparatus is provided for preventing and extinguishing fires in an engine compartment of a motor vehicle. The apparatus includes a collision sensor assembly supported by the motor vehicle and a fire extinguisher module supported by the motor vehicle. The fire extinguisher module includes a valve assembly. A valve control assembly is electrically connected to the collision sensor assembly, is supported by the fire extinguisher module, and is employed for controlling the valve assembly. A manifold assembly is supported by the motor vehicle and is connected to the valve assembly. The manifold assembly receives a quantity of fire extinguishant from the fire extinguisher module when the valve assembly is operated by the valve control assembly. The manifold assembly includes a first manifold branch which extends along a first side of the engine compartment and includes a second manifold branch which extends along a second side of the engine compartment. A plurality of nozzle assemblies are supported by and are arrayed along the manifold branches. The nozzle assemblies direct flow of a quantity of fire extinguishant toward an engine positioned between the first manifold branch and the second manifold branch. The collision sensor assembly may be responsive to a collision-induced movement of a vehicle radiator assembly. A rollover sensor assembly may also be employed. A high-temperature sensor assembly may also be employed. An ignition-circuit-deactivator assembly may also be employed for opening the ignition circuit in response to a sensed condition.
