Abstract: A condensation system for a reservoir, which stores fuel cryogenically, is disclosed. A portion of the fuel exists as a boil-off gas with a first vapor quality. The condensation system includes an absorption unit coupled to the reservoir and is configured to receive and mix the boil-off gas with a refrigerant, forming a liquid solution. A distillation unit is coupled to the absorption unit to receive the liquid solution at a supplemented pressure, and is configured to separate the fuel to a gaseous state from the liquid solution. Further, a cooling circuit is configured to receive the fuel in the gaseous state from the distillation unit at the supplemented pressure and a supplemented temperature, and deliver the fuel to the reservoir at a lower pressure and a temperature, with a vapor quality lower than the first vapor quality.

Abstract: A method to rotate crankshaft of an engine via a pneumatic system is disclosed herein. The engine includes a plurality of engine cylinders. The pneumatic system has an air compressor and a plurality of valves. The method includes monitoring angular orientation of the crankshaft and determining the position of the piston of the plurality of engine cylinders. An engine cylinder amongst the plurality of engine cylinders is selected with the piston in one of a power stroke or a compression stroke. A valve corresponding to the engine cylinder is activated. Upon activation of the valve, compressed air is supplied to the engine cylinder by the air compressor. The valve is then deactivated as the piston attains completion of one power stroke or one compression stroke. The activation, supply, and deactivation are sequentially repeated for each of the plurality of engine cylinders, based on predetermined firing order of the engine.
