Abstract
An emergency fuel supply system comprising a main fuel tank having a separate internal fuel reservoir which automatically refills itself with a reserve quantity of fresh fuel each time the main tank of the vehicle is refilled. A remotely controlled electric fuel pump or dump valve permits the vehicle operator to selectively jettison the reserve fuel into the main tank, either to provide a reserve supply in an emergency when the fuel in the main tank is depleted, or to empty the reserve tank of possibly stale fuel so that it may be refilled the next time the main tank is refilled.
Claims7
An emergency fuel supply system for an automotive vehicle having an internal combustion engine, characterized by:
- (a) a fuel tank, said fuel tank having a main reservoir and filler means for introducing fuel therein,
- (b) said main reservoir having a smaller auxiliary reservoir contained therein having an upper opening for receiving and being substantially filled with fuel whenever said main reservoir is substantially filled,
- (c) fuel level indicator means for detecting and indicating the quantity of fuel remaining in said main reservoir, and for indicating incipient fuel exhaustion, to an operator of said vehicle,
- (d) first fuel supply means for transferring fuel from said main reservoir to said engine,
- (e) second fuel supply means for transferring fuel from said auxiliary reservoir to said first fuel supply means, and
- (f) selector switch means for selectively activating said second fuel supply means to transfer fuel from said auxiliary reservoir to said first fuel supply means after said main fuel reservoir has been substantially exhausted.
