Abstract
The present disclosure provides a dispensing system for a fuel additive. This dispensing system comprises two subsystems, one being located in a vehicle and the other located in a fuel pump. The dispensing system of the present disclosure dispenses a liquid fuel additive into a fuel additive storage container of a vehicle at the time the vehicle is fueled at a fuel pump. According to the present disclosure, the fuel additive is a solution of urea, water and a monohydric or polyhydric alcohol. A gasoline performance enhancer may also be used as a fuel additive in the dispensing systems of the present disclosure.
Claims25
A dispensing system for a fuel additive comprising:
- a mobil subsystem adapted to be incorporated into a vehicle, said mobile subsystem comprising:
- an additive storage container, adapted for storing said fuel additive;
- a level sensor operatively connected to said additive storage container;
- a signal transmitter operatively connected to said level sensor;
- and
- a double fill tube comprising a fuel fill tube connected to a fuel tank and a fuel additive fill tube connected to said additive storage container;
- and
- a stationary subsystem, adapted to be incorporated into a vehicle fuel dispenser, said stationary subsystem comprising:
- a stationary storage container, adapted for storing said fuel additive, said stationary storage container bearing a pump and a firsts valve;
- a nozzle bearing a fuel additive dispensing spout and a fuel dispensing spout, said fuel additive dispensing spout bearing a second valve;
- a fuel additive dispensing conduit, said conduit extending from said stationary storage container to said fuel additive dispensing spout of said nozzle;
- a receiving device capable of receiving a signal transmitted from said signal transmitter of said mobile subsystem;
- and
- a control unit operatively connected to said receiving device, said first valve, said second valve, and said pump.
A dispensing system for a fuel additive which is used to reduce emissions from the operation of a vehicle comprising:
- a mobile subsystem adapted to be incorporated into said vehicle, said mobile subsystem comprising:
- an amount of a fuel additive;
- an additive storage container adapted for storing said fuel additive;
- a mechanical level indicator;
- and
- a double fill tube comprising a fuel fill tube connected to a fuel tank and a fuel additive fill tube connected to said additive storage container;
- and
- a stationary subsystem incorporated into a vehicle fuel dispenser, said stationary subsystem comprising:
- a stationary storage container adapted for storing said fuel additive, said stationary storage container bearing a pump and a first valve;
- a nozzle bearing a fuel additive dispensing spout and a fuel dispensing spout, said fuel additive dispensing spout bearing a second valve and a mechanical receptor for said mechanical level indicator;
- a fuel additive dispensing conduit, said conduit extending from said stationary storage container to said fuel additive dispensing spout of said nozzle;
- and
- a control unit operatively connected to say mechanical receptor, said first valve, said second valve, and said pump.
