Abstract
A dual-fuel tank houses one or more compressed natural gas (CNG) vessels and one or more diesel fuel vessels. The diesel fuel vessels are generally disposed laterally outwardly from the CNG vessels to provide a buffer that protects the CNG vessels from side impacts. The dual-fuel tank may be retrofit onto a diesel locomotive in place of the locomotive's diesel fuel tank to convert the locomotive into a dual-fuel locomotive. The dual-fuel tank may be provided in a ship.
Claims32
A dual-fuel railroad locomotive comprising:
- a chassis;
- a plurality of railroad wheels mounted to the chassis;
- a dual-fuel diesel cycle engine supported by the chassis and operatively connected to the wheels to drive the wheels to propel the locomotive along a railroad track;
- a dual-fuel tank mounted to the chassis, the dual-fuel tank including:
- at least one liquid fuel vessel, and
- at least one pressurized fuel vessel.
A method of converting a railroad locomotive into a dual fuel locomotive, the method comprising:
- removing a single-fuel tank from the railroad locomotive;
- mounting a dual-fuel tank to the railroad locomotive in place of the single-fuel tank, the dual-fuel tank including:
- at least one liquid fuel vessel and at least one pressurized fuel vessel.
A dual-fuel tank comprising:
- a frame housing one or more liquid fuel vessels and one or more pressurized fuel vessels;
- wherein the pressurized fuel vessels are disposed laterally inward of the liquid fuel vessels such that the liquid fuel vessels protect the pressurized fuel vessels from a lateral impact to the frame.
