Patent ID: 11247894

Abstract:
A fuel delivery system automatically selects one out of several available fuels for a vehicle having a specialized fuel filler neck. A dispenser pump assembly includes a pump base, a hose assembly and a nozzle assembly which includes a nozzle spout and a cylindrical collar member slidably mounted on the nozzle spout. A sensor on the nozzle assembly generates a signal, based on a position of the collar when the spout is fully inserted into a fuel filler neck of the vehicle. The signal is transmitted via wires, wireless signal, fiber-optic cables or other medium. An electronic controller in the pump base selects an appropriate fuel, based on the signal received from the sensor. If the available fuels include percentages of ethanol or other additives, a precision blending system ensures that the correct amount of additive is provided. Methods of selecting a fuel using the system hereof are also disclosed.
