ABSTRACT:
A fuel and vapor control system for motor vehicle applications is disclosed. The fuel and vapor control system regulates the refueling operation to maintain a sufficient vapor dome within the motor vehicle fuel tank to prevent over-filling thereof upon malfunction of a fuel nozzle's automatic shut-off mechanism. The fuel and vapor control system includes a first valve assembly for controlling the flow of fuel vapors to a vapor capture device, a second valve assembly for controlling actuation of the nozzle shut-off mechanism, and a third valve assembly for controlling the delivery of liquid fuel into the fuel tank in response to actuation of the first and second valve assemblies. A fourth valve assembly inhibits the emission of evaporative fuel vapors upon withdrawal of the nozzle from the fill pipe. The various valve assemblies cooperate to inhibit leakage of liquid fuel and vapors from the motor vehicle fuel system upon impact and/or the occurrence of a roll-over situation.
