Abstract

Abstract A standard fire extinguisher is modified by providing a quick-disconnect coupling interposed in its hose, so that its nozzle can be disconnected and the coupling can be connected to a mating quick-disconnect coupling exposed on a bonnet or the like covering a vehicle engine. The bonnet may be in the passenger compartment of the vehicle and opens to provide engine access. Tubing, inside the bonnet and connecting to the coupling on the bonnet, has discharge openings to distribute fire extinguishing fluid in fighting a fire in the engine compartment.
