Abstract
An automatic fueling system containing a fueling machine having a nozzle mechanism comprising an injection pipe with a nozzle insertion sensor thereon, and a plurality of fueling nozzles contained in the injection pipe, each for dispensing a predetermined sort of fuel, and a fuel port sensor; and a data input/output unit for performing a signal transmission to and from the fueling machine; wherein the insertion of one of the nozzles is carried out to an automobile to be fueled having a signal generator thereon by the movement of the fueling machine based on the signal transmission between the fuel port sensor and the signal generator, and the fueling is suspended by the detection of a required level of fueling.
Claims6
An automatic fueling system comprising:
- a fueling machine comprising a nozzle mechanism comprising an injection pipe having a nozzle insertion sensor thereon, and a plurality of fueling nozzles contained in said injection pipe, each for dispensing a predetermined sort of fuel, and a fuel port sensor;
- and
- a data input/output unit for performing a signal transmission to and from said fueling machine;
- wherein the insertion of one of said nozzles is carried out to an automobile to be fueled having a signal generator thereon by the movement of said fueling machine based on the signal transmission between said fuel port sensor and said signal generator, and the fueling is suspended by the detection of a required level of fueling;
- wherein said fueling machine further comprises a fuel control unit comprising a fuel-sort discrimination unit and a full-tank fueling unit, said fuel control unit causes to function said fuel sort discrimination unit by the receipt of a nozzle-insertion signal from said nozzle-insertion sensor, and causes to function said full-tank fueling unit to start fueling when said fuel sort discrimination unit detects a correct fuel selection, and the fueling is suspended by the detection of a required level of fueling by said full-tank fueling unit.
An automatic fueling system comprising:
- a first fueling machine and a second fueling machine, each comprising a fuel control unit comprising a fuel-sort discrimination unit, a full-tank fueling unit, an injection pipe having a nozzle-insertion sensor thereon, and a plurality of fueling nozzles contained in said injection pipe, each for dispensing a predetermined sort of fuel, and a fuel port sensor;
- and
- a first data input/output unit and a second data input/output unit for performing a signal transmission respectively to and from said first fueling machine and said second fueling machine;
- wherein said first fueling machine performs the insertion of one of said nozzles thereof to an automobile to be fueled having a signal generator thereon by the movement of said fueling machine based on the signal transmission between said fuel port sensor and said signal generator, said fuel control unit causes to function said fuel sort discrimination unit by the receipt of a nozzle-insertion signal from said nozzle-insertion sensor, and causes to function said full-tank fueling unit to start fueling when said fuel sort discrimination unit detects a correct fuel selection, the fueling is suspended by the detection of a required level of fueling by said full-tank fueling unit, and said first data input/output unit inhibits an input from said second data input/output unit by outputting a data input/output inhibition signal to said second data input/output unit when a fueling data is input to said first data input/output unit.
