Disclosed herein is a fuel injection apparatus for injecting fuel into a fuel cartridge. The fuel injection apparatus may include, for example, a container for fuel storage, a fuel supply pipe in fluid communication with the container, a first valve installed on the fuel supply pipe, a pump installed on the fuel supply pipe, a pressure gauge installed on the fuel supply pipe, and a bypass pipe fluidly connecting the container with the fuel supply pipe. A second valve may be installed on the bypass pipe. Methods for injecting fuel into a fuel cartridge are also disclosed herein.

1. A fuel injection apparatus, comprising: a container for fuel storage;a fuel supply pipe in fluid communication with the container;a first valve installed on the fuel supply pipe;a pump installed on the fuel supply pipe between the container and the first valve;a pressure gauge installed on the fuel supply pipe between the first valve and the pump; anda bypass pipe fluidly connecting the container with the fuel supply pipe,wherein a second valve is installed on the bypass pipe,wherein the container is fluidly connected to a buffering container via a connection pipe, andwherein a second pump is installed on the connection pipe. 2. The fuel injection apparatus of claim 1, wherein the bypass pipe fluidly connects to the fuel supply pipe at a point between the first valve and the pump. 3. The fuel injection apparatus of claim 1, wherein the connection pipe is fluidly connected to the fuel supply pipe via a control valve. 4. The fuel injection apparatus of claim 3, wherein the control valve comprises a three-way valve. 5. A fuel injection system, comprising the fuel injection apparatus of claim 1 and further comprising a fuel cartridge in fluid communication with the fuel injection apparatus. 6. A method of injecting fuel, the method comprising: providing the fuel injection system of claim 5;eliminating fuel remaining in the fuel cartridge;eliminating air in the fuel supply pipe; andinjecting fuel from the container to the fuel cartridge. 7. The method of injecting fuel of claim 6, wherein eliminating fuel remaining in the fuel cartridge comprises shutting the second valve, opening the first valve and using the pump to pump air and fuel remaining in the interior of the fuel cartridge to the container through the fuel supply pipe. 8. The method of claim 7, wherein eliminating air in the fuel supply pipe comprises shutting the first valve, opening the second valve, and using the pump to inject fuel from the container to the supply pipe via the bypass pipe. 9. The method of claim 8, wherein injecting fuel from the container to the fuel cartridge comprises shutting the second valve, opening the first valve, and using the pump to pump fuel from the container to the fuel cartridge. 10. The method of injecting fuel of claim 6, wherein eliminating fuel remaining in the cartridge comprises discharging fuel remaining in the fuel cartridge and monitoring a first pressure comparison. 11. The method of injecting fuel of claim 10, wherein eliminating fuel remaining in the cartridge further comprises comparing a discharge pressure between the pump and the fuel cartridge with a pre-set first reference pressure, performing pumping when the discharge pressure is higher than the first reference pressure, and stopping pumping when the discharge pressure is lower than the first reference pressure. 12. The method of injecting fuel of claim 10, wherein injecting fuel from the container to the fuel cartridge comprises supplying fuel from the container to the fuel cartridge and monitoring a second pressure comparison. 13. The method of injecting fuel of claim 12, wherein injecting fuel from the container to the fuel cartridge further comprises comparing an injection pressure between the pump and the fuel cartridge with a pre-set second reference pressure, performing pumping when the injection pressure is lower than the second reference pressure, and stopping pumping when the injection pressure is higher than the second reference pressure.
