Abstract

A fueling system for an engine includes a fuel tank, a controller, a fuel nozzle receptacle connected to the fuel tank, the fuel nozzle receptacle including a receptacle sensor configured to send a signal to the contoller indicative of whether a fuel nozzle of a fuel dispenser is received in the fuel nozzle receptacle, and an electric fill slop valve between the fuel tank and the fuel nozzle receptacle, the electric fill stop valve being, configured to be controlled to open and close in response to a signal from the controller. The controller can be configured to receive at least one of (a) a signal whether a fuel nozzle of a fuel dispenser is received in a fuel nozzle receptacle connected to the fuel tank, and (b) a signal whether a fuel level of the fuel tank is full, and to control the electric fill stop valve to close when a signal is sent to the controller that at least one of (a) the fuel nozzle is not received in the fuel nozzle receptacle when the controller is configured to receive the signal whether the fuel nozzle of a fuel dispenser is received in the fuel nozzle receptacle, and (b) the fuel level of the fuel tank is full when the controller is configured to receive the signal whether the fuel level of the fuel tank is full.

First claim

What is claimed is:

1. A fueling system for an engine, comprising:
a fuel tank;
a fuel nozzle receptacle connected to the fuel tank;
a controller;
an electric fill stop valve disposed between the fuel nozzle receptacle and the fuel tank, the electric fill stop valve being configured to be controlled to open and close in response to a signal from the controller,
wherein the controller is configured to receive at least one of (a) a signal whether a fuel nozzle of a fuel dispenser is received in the fuel nozzle receptacle, and (b) a signal whether a fuel level of the fuel tank is full, and to control the electric fill stop valve to close when a signal is sent to the controller that at least one of (a) the fuel nozzle is not received in the fuel nozzle receptacle when the controller is configured to receive the signal whether the fuel nozzle of a fuel dispenser is received in the fuel nozzle receptacle, and (b) the fuel level of the fuel tank is full when the controller is configured to receive the signal whether the fuel level of the fuel tank is full,
the fueling system comprising a locking mechanism on the fuel nozzle receptacle, the locking mechanism being linked to the controller and being controlled to permit the fuel nozzle to be received in the fuel nozzle receptacle when the engine and non-fill related functions are ‘off’ and fill related functions of the fueling system are “on” and preventing the fuel nozzle from being received in the fuel nozzle receptacle when the engine and non-fill related functions are “off” and fill related functions of the fueling system are off.

2. The fueling system as set forth in claim 1 , wherein the fuel nozzle receptacle includes a receptacle sensor configured to send the signal to the controller whether the fuel nozzle is received in the fuel nozzle receptacle.

3. The fueling system as set forth in claim 1 , wherein the controller is configured to control the electric fill stop valve to close when the controller receives the signal that the fuel nozzle is not received in the fuel nozzle receptacle.

4. The fueling system as set forth in claim 1 , wherein the controller is configured to prevent operation of non-fill related functions of the engine when the controller receives a signal that the fuel nozzle is received in the fuel nozzle receptacle.

5. The fueling system as set forth in claim 4 , wherein the controller is configured to stop operation of non-fill related functions of the engine when the controller receives the signal that the fuel nozzle is received in the fuel nozzle receptacle.

6. The fueling system as set forth in claim 4 , wherein the controller is configured to operate non-fill related functions of the engine when at least one condition is satisfied, and wherein a condition of the at least one condition is satisfied when the controller receives a signal that the fuel nozzle is not received in the fuel nozzle receptacle.

7. The fueling system as set forth in claim 1 , further comprising a second fuel tank, and a second electric fill stop valve between the second fuel tank and the fuel nozzle receptacle, the second electric fill stop valve being configured to be controlled to open and close in response to a signal from the controller.

8. The fueling system as set forth in claim 7 , wherein the controller is configured to control the second electric fill stop valve to close when at least one condition is satisfied, and wherein a condition of the at least one condition is satisfied when the controller receives the signal that the fuel nozzle is not received in the fuel nozzle receptacle.

9. The fueling system as set forth in claim 7 , further comprising a first fuel level sensor configured to sense a first fuel level in the first fuel tank and to send a signal to the controller indicative of whether the first fuel level is full, a second fuel level sensor configured to sense a second fuel level in the second fuel tank and to send a signal to the controller indicative of whether the second fuel level is full.

10. The fueling system as set forth in claim 9 , wherein the first fuel level sensor is configured to send a signal to the controller that the first fuel level is full and the second fuel level sensor is configured to send a signal to the controller that the second fuel level is full, and wherein the controller is configured to control the first electric fill stop valve to close in response to the signal from the first fuel level sensor that the first fuel level is full, and to control the second electric fill stop valve to close in response to the signal from the second fuel level sensor that the second fuel level is full.

11. The fueling system as set forth in claim 9 , wherein the first fuel level sensor is configured to send a signal to the controller that the first fuel level is below full and the second fuel level sensor is configured to send a signal to the controller that the second fuel level is below full, wherein the controller is configured to control the first electric fill stop valve to open when at least one first fuel tank condition is satisfied, and wherein a condition of the at least one first fuel tank condition is satisfied when the controller receives a signal that the first fuel level is below full, and wherein the controller is configured to control the second electric fill stop valve to open when at least one second fuel tank condition is satisfied, and wherein a condition of the at least one second fuel tank condition is satisfied when the controller receives a signal that the second fuel level is below full.

12. The fueling system as set forth in claim 9 , wherein the first fuel level sensor is configured to send a signal to the controller that the first fuel level is below full and the second fuel level sensor is configured to send a signal to the controller that the second fuel level is below full, and wherein the controller is configured to control the first electric fill stop valve to open when the first fuel level sensor sends the signal to the controller indicating that the first fuel level is below full, and to control the second electric fill stop valve to open when the second fuel level sensor sends the signal to the controller indicating that the second fuel level is below full.

13. The fueling system as set forth in claim 9 , wherein the first fuel level sensor is configured to send a signal to the controller that the first fuel level is below full and the second fuel level sensor is configured to send a signal to the controller that the second fuel level is below full, and wherein the controller is configured to control the first electric fill stop valve to open when (a) the controller receives a signal that the fuel nozzle is received in the fuel nozzle receptacle and (b) the first fuel level sensor sends the signal to the controller indicating that the first fuel level is below full, and to control the second electric fill stop valve to open when (a) the controller receives the signal that the fuel nozzle is received in the fuel nozzle receptacle and (b) the second fuel level sensor sends the signal to the controller indicating that the second fuel level is below full.

14. The fueling system as set forth in claim 1 , further comprising a fuel level sensor in the fuel tank, the fuel level sensor being configured to sense a fuel level in the fuel tank and to send the signal to the controller whether the fuel level is full.

15. The fueling system as set forth in claim 14 , wherein the fuel level sensor is configured to send a signal to the controller that the fuel level is below full, and wherein the controller is configured to control the ele
