초록 ▼

A fuel system for an engine includes a fuel line that delivers fuel from a main fuel tank to the engine and a first control device that releases a flow of the fuel from the main fuel tank into the fuel line. An auxiliary fuel tank is connected to the fuel line, and a second control device controls a flow of the fuel between the auxiliary fuel tank and the fuel line. After the fuel is released from the main fuel tank into the fuel line, the second control device fills the auxiliary fuel tank with the fuel from the main fuel tank.

대표청구항 ▼

1. A fuel system for an engine, comprising: a fuel line configured to deliver fuel from a removable main fuel tank to the engine;a first control device configured to release a flow of the fuel from the removable main fuel tank into the fuel line in response to an installation of the removable main fuel tank;an auxiliary fuel tank connected to the fuel line, wherein the fuel line is further configured to deliver fuel from the auxiliary fuel tank to the engine;a monitoring device configured to detect a fuel pressure of the fuel system, wherein an increase in the fuel pressure is associated with the installation of the removable main fuel tank; anda second control device configured to fill the auxiliary fuel tank with at least a portion of the fuel released from the removable main fuel tank in response to the monitoring device having detected the increase in the fuel pressure, and wherein the second control device is further configured to release the portion of the fuel from the auxiliary fuel tank into the fuel line for consumption by the engine in response to the monitoring device detecting a decrease in the fuel pressure. 2. The fuel system of claim 1, wherein the second control device is further configured to prohibit a release of the portion of the fuel from the auxiliary fuel tank into the fuel line while the fuel is being delivered from the removable main fuel tank to the engine. 3. The fuel system of claim 1, wherein in response to detecting the decrease in the fuel pressure, the first control device is configured to prohibit both the flow of the fuel from the removable main fuel tank into the fuel line and a flow of the fuel from the fuel line into the removable main fuel tank. 4. The fuel system of claim 3, wherein the removable main fuel tank is substantially empty of the fuel while the fuel is being delivered from the auxiliary fuel tank to the engine. 5. The fuel system of claim 1, wherein the first control device is further configured to release the flow of the fuel from the removable main fuel tank into the fuel line prior to detecting the decrease in the fuel pressure. 6. A method, comprising: releasing a flow of fuel from a removable main fuel tank into a fuel line for consumption by an engine, wherein the fuel is released into the fuel line in response to installation of the removable main fuel tank;detecting an increase in fuel pressure associated with the installation of the removable main fuel tank;filling an auxiliary fuel tank with at least a portion of the fuel from the removable main fuel tank in response to detecting the increase in fuel pressure;detecting a decrease in fuel pressure; andreleasing the portion of the fuel from the auxiliary fuel tank into the fuel line for consumption by the engine in response to detecting the decrease in fuel pressure. 7. The method of claim 6, further comprising prohibiting a release of the portion of the fuel from the auxiliary fuel tank into the fuel line while the fuel is being delivered from the removable main fuel tank to the engine. 8. The method of claim 6, wherein the decrease in fuel pressure is associated with a removal of the removable main fuel tank. 9. The method of claim 6, wherein the removable main fuel tank is substantially empty of the fuel while the portion of the fuel is being released from the auxiliary fuel tank. 10. The fuel system of claim 1, wherein the decrease in the fuel pressure is associated with a decreased amount of the fuel in the removable main fuel tank. 11. The fuel system of claim 1, wherein the monitoring device comprises a temperature compensating pressure switch, wherein the temperature compensating pressure switch is configured to compensate for changes in the fuel pressure due to environmental temperature changes. 12. The method of claim 6, wherein filling the auxiliary tank comprises: opening a control device allowing the portion of the fuel to flow into the auxiliary fuel tank in response to detecting the increase in fuel pressure; andclosing the control device in response to the control device detecting a change in auxiliary fuel pressure associated with the auxiliary fuel tank being full.
