Patent ID: 7587998

Claim:
A power plant comprising: an internal combustion engine; a fuel conversion device that coverts a fuel to be supplied to the internal combustion engine from a before-conversion fuel to an after-conversion fuel; a first fuel supply device that supplies the fuel conversion device with the before-conversion fuel; a second fuel supply device that supplies the internal combustion engine with the after-conversion fuel, the after-conversion fuel being the fuel that has been converted by the fuel conversion device; and a controller that is communicated with the internal combustion engine, the fuel conversion device, the first fuel supply device and the second fuel supply device; wherein the controller is configured to: supply the fuel conversion device with the before-conversion fuel by operating the first fuel supply device; control the temperature of the fuel conversion device in a first temperature range to evaporate the before-conversion fuel to produce a first after-conversion fuel; control the temperature of the fuel conversion device in a second temperature range to reform the before-conversion fuel to produce a second after-conversion fuel; and supply the internal combustion engine with the after-conversion fuel by operating the second fuel supply device.
